// The WriteRecords operation enables you to write your time series data into
// Timestream. You can specify a single data point or a batch of data points to be
// inserted into the system. Timestream offers you with a flexible schema that auto
// detects the column names and data types for your Timestream tables based on the
// dimension names and data types of the data points you specify when invoking
// writes into the database. Timestream support eventual consistency read
// semantics. This means that when you query data immediately after writing a batch
// of data into Timestream, the query results might not reflect the results of a
// recently completed write operation. The results may also include some stale
// data. If you repeat the query request after a short time, the results should
// return the latest data. Service quotas apply
// (https://docs.aws.amazon.com/timestream/latest/developerguide/ts-limits.html).
// See code sample
// (https://docs.aws.amazon.com/timestream/latest/developerguide/code-samples.write.html)
// for details. Upserts You can use the Version parameter in a WriteRecords request
// to update data points. Timestream tracks a version number with each record.
// Version defaults to 1 when not specified for the record in the request.
// Timestream will update an existing record’s measure value along with its Version
// upon receiving a write request with a higher Version number for that record.
// Upon receiving an update request where the measure value is the same as that of
// the existing record, Timestream still updates Version, if it is greater than the
// existing value of Version. You can update a data point as many times as desired,
// as long as the value of Version continuously increases. For example, suppose you
// write a new record without indicating Version in the request. Timestream will
// store this record, and set Version to 1. Now, suppose you try to update this
// record with a WriteRecords request of the same record with a different measure
// value but, like before, do not provide Version. In this case, Timestream will
// reject this update with a RejectedRecordsException since the updated record’s
// version is not greater than the existing value of Version. However, if you were
// to resend the update request with Version set to 2, Timestream would then
// succeed in updating the record’s value, and the Version would be set to 2. Next,
// suppose you sent a WriteRecords request with this same record and an identical
// measure value, but with Version set to 3. In this case, Timestream would only
// update Version to 3. Any further updates would need to send a version number
// greater than 3, or the update requests would receive a RejectedRecordsException.
