        &quot;valueType&quot;: { # `Type` represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable&#x27;s existing untyped APIs, each `Type` includes an `Encoding` which describes how to convert to or from the underlying data. Each encoding can operate in one of two modes: - Sorted: In this mode, Bigtable guarantees that `Encode(X) &lt;= Encode(Y)` if and only if `X &lt;= Y`. This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards. If `value_type` is `Aggregate`, written data must be compatible with: * `value_type.input_type` for `AddInput` mutations
          &quot;aggregateType&quot;: { # A value that combines incremental updates into a summarized value. Data is never directly written or read using type `Aggregate`. Writes provide either the `input_type` or `state_type`, and reads always return the `state_type` . # Aggregate

Currently, this only affects how the key is read via a GoogleSQL query from the ExecuteQuery API. For a SQL query, the _key column is still read as raw bytes. But queries can reference the key fields by name, which will be decoded from _key using provided type and encoding. Queries that reference key fields will fail if they encounter an invalid row key. For example, if _key = &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; with the following schema: { fields { field_name: &quot;id&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;date&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;product_code&quot; type { int64 { encoding: big_endian_bytes {} } } } encoding { delimited_bytes { delimiter: &quot;#&quot; } } } The decoded key parts would be: id = &quot;some_id&quot;, date = &quot;2024-04-30&quot;, product_code = 1245427 The query &quot;SELECT _key, product_code FROM table&quot; will return two columns: /------------------------------------------------------\ | _key | product_code | | --------------------------------------|--------------| | &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; | 1245427 | \------------------------------------------------------/ The schema has the following invariants: (1) The decoded field values are order-preserved. For read, the field values will be decoded in sorted mode from the raw bytes. (2) Every field in the schema must specify a non-empty name. (3) Every field must specify a type with an associated encoding. The type is limited to scalar types only: Array, Map, Aggregate, and Struct are not allowed. (4) The field names must not collide with existing column family names and reserved keywords &quot;_key&quot; and &quot;_timestamp&quot;. The following update operations are allowed for row_key_schema: - Update from an empty schema to a new schema. - Remove the existing schema. This operation requires setting the `ignore_warnings` flag to `true`, since it might be a backward incompatible change. Without the flag, the update request will fail with an INVALID_ARGUMENT error. Any other row key schema update operation (e.g. update existing schema columns names or types) is currently unsupported.

      &quot;valueType&quot;: { # `Type` represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable&#x27;s existing untyped APIs, each `Type` includes an `Encoding` which describes how to convert to or from the underlying data. Each encoding can operate in one of two modes: - Sorted: In this mode, Bigtable guarantees that `Encode(X) &lt;= Encode(Y)` if and only if `X &lt;= Y`. This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards. If `value_type` is `Aggregate`, written data must be compatible with: * `value_type.input_type` for `AddInput` mutations
        &quot;aggregateType&quot;: { # A value that combines incremental updates into a summarized value. Data is never directly written or read using type `Aggregate`. Writes provide either the `input_type` or `state_type`, and reads always return the `state_type` . # Aggregate

For read, the field values will be decoded in sorted mode from the raw bytes. (2) Every field in the schema must specify a non-empty name. (3) Every field must specify a type with an associated encoding. The type is limited to scalar types only: Array, Map, Aggregate, and Struct are not allowed. (4) The field names must not collide with existing column family names and reserved keywords &quot;_key&quot; and &quot;_timestamp&quot;.

Any other row key schema update operation (e.g. update existing schema columns names or types) is currently unsupported.

      &quot;valueType&quot;: { # `Type` represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable&#x27;s existing untyped APIs, each `Type` includes an `Encoding` which describes how to convert to or from the underlying data. Each encoding can operate in one of two modes: - Sorted: In this mode, Bigtable guarantees that `Encode(X) &lt;= Encode(Y)` if and only if `X &lt;= Y`. This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards.

Any empty fields that aren&#x27;t omitted are replaced with the fixed byte pair {0x00, 0x00}. Examples: - STRUCT() -&gt; &quot;\00\00&quot; - STRUCT(&quot;&quot;) -&gt; &quot;\00\00&quot; - STRUCT(&quot;&quot;, &quot;&quot;) -&gt; &quot;\00\00&quot; - STRUCT(&quot;&quot;, &quot;B&quot;) -&gt; &quot;\00\00&quot; + &quot;\00\01&quot; + &quot;B&quot; - STRUCT(&quot;A&quot;, &quot;&quot;) -&gt; &quot;A&quot; - STRUCT(&quot;&quot;, &quot;B&quot;, &quot;&quot;) -&gt; &quot;\00\00&quot; + &quot;\00\01&quot; + &quot;B&quot; - STRUCT(&quot;A&quot;, &quot;&quot;, &quot;C&quot;) -&gt; &quot;A&quot; + &quot;\00\01&quot; + &quot;\00\00&quot; + &quot;\00\01&quot; + &quot;C&quot; Since null bytes are always escaped, this encoding can cause size blowup for encodings like `Int64.BigEndianBytes` that are likely to produce many such bytes.

The schema is used to decode the raw row key bytes into a structured format. The order of field declarations in this schema is important, as it reflects how the raw row key bytes are structured. Currently, this only affects how the key is read via a GoogleSQL query from the ExecuteQuery API. For a SQL query, the _key column is still read as raw bytes. But queries can reference the key fields by name, which will be decoded from _key using provided type and encoding. Queries that reference key fields will fail if they encounter an invalid row key. For example, if _key = &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; with the following schema: { fields { field_name: &quot;id&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;date&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;product_code&quot; type { int64 { encoding: big_endian_bytes {} } } } encoding { delimited_bytes { delimiter: &quot;#&quot; } } } The decoded key parts would be: id = &quot;some_id&quot;, date = &quot;2024-04-30&quot;, product_code = 1245427 The query &quot;SELECT _key, product_code FROM table&quot; will return two columns: /------------------------------------------------------\ | _key | product_code | | --------------------------------------|--------------| | &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; | 1245427 | \------------------------------------------------------/ The schema has the following invariants: (1) The decoded field values are order-preserved. For read, the field values will be decoded in sorted mode from the raw bytes. (2) Every field in the schema must specify a non-empty name. (3) Every field must specify a type with an associated encoding. The type is limited to scalar types only: Array, Map, Aggregate, and Struct are not allowed. (4) The field names must not collide with existing column family names and reserved keywords &quot;_key&quot; and &quot;_timestamp&quot;. The following update operations are allowed for row_key_schema: - Update from an empty schema to a new schema. - Remove the existing schema. This operation requires setting the `ignore_warnings` flag to `true`, since it might be a backward incompatible change. Without the flag, the update request will fail with an INVALID_ARGUMENT error. Any other row key schema update operation (e.g. update existing schema columns names or types) is currently unsupported.

  <pre>Gets the access control policy for a Bigtable resource. Returns an empty policy if the resource exists but does not have a policy set.

Args:
  resource: string, REQUIRED: The resource for which the policy is being requested. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for `GetIamPolicy` method.
  &quot;options&quot;: { # Encapsulates settings provided to GetIamPolicy. # OPTIONAL: A `GetPolicyOptions` object for specifying options to `GetIamPolicy`.
    &quot;requestedPolicyVersion&quot;: 42, # Optional. The maximum policy version that will be used to format the policy. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. Requests for policies with any conditional role bindings must specify version 3. Policies with no conditional role bindings may specify any valid value or leave the field unset. The policy in the response might use the policy version that you specified, or it might use a lower policy version. For example, if you specify version 3, but the policy has no conditional role bindings, the response uses version 1.

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { &quot;bindings&quot;: [ { &quot;role&quot;: &quot;roles/resourcemanager.organizationAdmin&quot;, &quot;members&quot;: [ &quot;user:mike@example.com&quot;, &quot;group:admins@example.com&quot;, &quot;domain:google.com&quot;, &quot;serviceAccount:my-project-id@appspot.gserviceaccount.com&quot; ] }, { &quot;role&quot;: &quot;roles/resourcemanager.organizationViewer&quot;, &quot;members&quot;: [ &quot;user:eve@example.com&quot; ], &quot;condition&quot;: { &quot;title&quot;: &quot;expirable access&quot;, &quot;description&quot;: &quot;Does not grant access after Sep 2020&quot;, &quot;expression&quot;: &quot;request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;)&quot;, } } ], &quot;etag&quot;: &quot;BwWWja0YfJA=&quot;, &quot;version&quot;: 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;) etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).

It is strongly suggested that systems make use of the `etag` in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An `etag` is returned in the response to `getIamPolicy`, and systems are expected to put that etag in the request to `setIamPolicy` to ensure that their change will be applied to the same version of the policy. **Important:** If you use IAM Conditions, you must include the `etag` field whenever you call `setIamPolicy`.

A page_size which is strictly positive will return at most that many items. A negative page_size will cause an error. Following the first request, subsequent paginated calls are not required to pass a page_size. If a page_size is set in subsequent calls, it must match the page_size given in the first request.
  pageToken: string, The value of `next_page_token` returned by a previous call.
  view: string, The view to be applied to the returned tables&#x27; fields. Only NAME_ONLY view (default), REPLICATION_VIEW and ENCRYPTION_VIEW are supported.
    Allowed values
      VIEW_UNSPECIFIED - Uses the default view for each method as documented in its request.
      NAME_ONLY - Only populates `name`.
      SCHEMA_VIEW - Only populates `name` and fields related to the table&#x27;s schema.
      REPLICATION_VIEW - Only populates `name` and fields related to the table&#x27;s replication state.
      ENCRYPTION_VIEW - Only populates `name` and fields related to the table&#x27;s encryption state.
      STATS_VIEW - Only populates `name` and fields related to the table&#x27;s stats (e.g. TableStats and ColumnFamilyStats).
      FULL - Populates all fields except for stats. See STATS_VIEW to request stats.

          &quot;valueType&quot;: { # `Type` represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable&#x27;s existing untyped APIs, each `Type` includes an `Encoding` which describes how to convert to or from the underlying data. Each encoding can operate in one of two modes: - Sorted: In this mode, Bigtable guarantees that `Encode(X) &lt;= Encode(Y)` if and only if `X &lt;= Y`. This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards. If `value_type` is `Aggregate`, written data must be compatible with: * `value_type.input_type` for `AddInput` mutations
            &quot;aggregateType&quot;: { # A value that combines incremental updates into a summarized value. Data is never directly written or read using type `Aggregate`. Writes provide either the `input_type` or `state_type`, and reads always return the `state_type` . # Aggregate

Currently, this only affects how the key is read via a GoogleSQL query from the ExecuteQuery API. For a SQL query, the _key column is still read as raw bytes. But queries can reference the key fields by name, which will be decoded from _key using provided type and encoding. Queries that reference key fields will fail if they encounter an invalid row key. For example, if _key = &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; with the following schema: { fields { field_name: &quot;id&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;date&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;product_code&quot; type { int64 { encoding: big_endian_bytes {} } } } encoding { delimited_bytes { delimiter: &quot;#&quot; } } } The decoded key parts would be: id = &quot;some_id&quot;, date = &quot;2024-04-30&quot;, product_code = 1245427 The query &quot;SELECT _key, product_code FROM table&quot; will return two columns: /------------------------------------------------------\ | _key | product_code | | --------------------------------------|--------------| | &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; | 1245427 | \------------------------------------------------------/ The schema has the following invariants: (1) The decoded field values are order-preserved. For read, the field values will be decoded in sorted mode from the raw bytes. (2) Every field in the schema must specify a non-empty name. (3) Every field must specify a type with an associated encoding. The type is limited to scalar types only: Array, Map, Aggregate, and Struct are not allowed. (4) The field names must not collide with existing column family names and reserved keywords &quot;_key&quot; and &quot;_timestamp&quot;. The following update operations are allowed for row_key_schema: - Update from an empty schema to a new schema. - Remove the existing schema. This operation requires setting the `ignore_warnings` flag to `true`, since it might be a backward incompatible change. Without the flag, the update request will fail with an INVALID_ARGUMENT error. Any other row key schema update operation (e.g. update existing schema columns names or types) is currently unsupported.

        &quot;valueType&quot;: { # `Type` represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable&#x27;s existing untyped APIs, each `Type` includes an `Encoding` which describes how to convert to or from the underlying data. Each encoding can operate in one of two modes: - Sorted: In this mode, Bigtable guarantees that `Encode(X) &lt;= Encode(Y)` if and only if `X &lt;= Y`. This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards. If `value_type` is `Aggregate`, written data must be compatible with: * `value_type.input_type` for `AddInput` mutations
          &quot;aggregateType&quot;: { # A value that combines incremental updates into a summarized value. Data is never directly written or read using type `Aggregate`. Writes provide either the `input_type` or `state_type`, and reads always return the `state_type` . # Aggregate

        &quot;valueType&quot;: { # `Type` represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable&#x27;s existing untyped APIs, each `Type` includes an `Encoding` which describes how to convert to or from the underlying data. Each encoding can operate in one of two modes: - Sorted: In this mode, Bigtable guarantees that `Encode(X) &lt;= Encode(Y)` if and only if `X &lt;= Y`. This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards.

      &quot;valueType&quot;: { # `Type` represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable&#x27;s existing untyped APIs, each `Type` includes an `Encoding` which describes how to convert to or from the underlying data. Each encoding can operate in one of two modes: - Sorted: In this mode, Bigtable guarantees that `Encode(X) &lt;= Encode(Y)` if and only if `X &lt;= Y`. This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards.

        &quot;aggregateType&quot;: { # A value that combines incremental updates into a summarized value. Data is never directly written or read using type `Aggregate`. Writes provide either the `input_type` or `state_type`, and reads always return the `state_type` . # Aggregate

Currently, this only affects how the key is read via a GoogleSQL query from the ExecuteQuery API. For a SQL query, the _key column is still read as raw bytes. But queries can reference the key fields by name, which will be decoded from _key using provided type and encoding. Queries that reference key fields will fail if they encounter an invalid row key. For example, if _key = &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; with the following schema: { fields { field_name: &quot;id&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;date&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;product_code&quot; type { int64 { encoding: big_endian_bytes {} } } } encoding { delimited_bytes { delimiter: &quot;#&quot; } } } The decoded key parts would be: id = &quot;some_id&quot;, date = &quot;2024-04-30&quot;, product_code = 1245427 The query &quot;SELECT _key, product_code FROM table&quot; will return two columns: /------------------------------------------------------\ | _key | product_code | | --------------------------------------|--------------| | &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; | 1245427 | \------------------------------------------------------/ The schema has the following invariants: (1) The decoded field values are order-preserved. For read, the field values will be decoded in sorted mode from the raw bytes. (2) Every field in the schema must specify a non-empty name. (3) Every field must specify a type with an associated encoding. The type is limited to scalar types only: Array, Map, Aggregate, and Struct are not allowed. (4) The field names must not collide with existing column family names and reserved keywords &quot;_key&quot; and &quot;_timestamp&quot;. The following update operations are allowed for row_key_schema: - Update from an empty schema to a new schema. - Remove the existing schema. This operation requires setting the `ignore_warnings` flag to `true`, since it might be a backward incompatible change. Without the flag, the update request will fail with an INVALID_ARGUMENT error. Any other row key schema update operation (e.g. update existing schema columns names or types) is currently unsupported.

This is useful anywhere sort order is important, for example when encoding keys. - Distinct: In this mode, Bigtable guarantees that if `X != Y` then `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For example, both &quot;{&#x27;foo&#x27;: &#x27;1&#x27;, &#x27;bar&#x27;: &#x27;2&#x27;}&quot; and &quot;{&#x27;bar&#x27;: &#x27;2&#x27;, &#x27;foo&#x27;: &#x27;1&#x27;}&quot; are valid encodings of the same JSON value. The API clearly documents which mode is used wherever an encoding can be configured. Each encoding also documents which values are supported in which modes. For example, when encoding INT64 as a numeric STRING, negative numbers cannot be encoded in sorted mode. This is because `INT64(1) &gt; INT64(-1)`, but `STRING(&quot;-00001&quot;) &gt; STRING(&quot;00001&quot;)`. # The type of data stored in each of this family&#x27;s cell values, including its full encoding. If omitted, the family only serves raw untyped bytes. For now, only the `Aggregate` type is supported. `Aggregate` can only be set at family creation and is immutable afterwards. If `value_type` is `Aggregate`, written data must be compatible with: * `value_type.input_type` for `AddInput` mutations
        &quot;aggregateType&quot;: { # A value that combines incremental updates into a summarized value. Data is never directly written or read using type `Aggregate`. Writes provide either the `input_type` or `state_type`, and reads always return the `state_type` . # Aggregate

But queries can reference the key fields by name, which will be decoded from _key using provided type and encoding. Queries that reference key fields will fail if they encounter an invalid row key. For example, if _key = &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; with the following schema: { fields { field_name: &quot;id&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;date&quot; type { string { encoding: utf8_bytes {} } } } fields { field_name: &quot;product_code&quot; type { int64 { encoding: big_endian_bytes {} } } } encoding { delimited_bytes { delimiter: &quot;#&quot; } } } The decoded key parts would be: id = &quot;some_id&quot;, date = &quot;2024-04-30&quot;, product_code = 1245427 The query &quot;SELECT _key, product_code FROM table&quot; will return two columns: /------------------------------------------------------\ | _key | product_code | | --------------------------------------|--------------| | &quot;some_id#2024-04-30#\x00\x13\x00\xf3&quot; | 1245427 | \------------------------------------------------------/ The schema has the following invariants: (1) The decoded field values are order-preserved. For read, the field values will be decoded in sorted mode from the raw bytes. (2) Every field in the schema must specify a non-empty name. (3) Every field must specify a type with an associated encoding. The type is limited to scalar types only: Array, Map, Aggregate, and Struct are not allowed. (4) The field names must not collide with existing column family names and reserved keywords &quot;_key&quot; and &quot;_timestamp&quot;. The following update operations are allowed for row_key_schema: - Update from an empty schema to a new schema. - Remove the existing schema. This operation requires setting the `ignore_warnings` flag to `true`, since it might be a backward incompatible change. Without the flag, the update request will fail with an INVALID_ARGUMENT error. Any other row key schema update operation (e.g. update existing schema columns names or types) is currently unsupported.
