[[modules-gateway-s3]]
=== S3 Gateway
*The S3 gateway is deprecated and will be removed in a future version.
Please use the <<modules-gateway-local,local
gateway>> instead.*
S3 based gateway allows to do long term reliable async persistency of
the cluster state and indices directly to Amazon S3. Here is how it can
be configured:
[source,js]
--------------------------------------------------
cloud:
aws:
access_key: AKVAIQBF2RECL7FJWGJQ
secret_key: vExyMThREXeRMm/b/LRzEB8jWwvzQeXgjqMX+6br
gateway:
type: s3
s3:
bucket: bucket_name
--------------------------------------------------
You’ll need to install the `cloud-aws` plugin, by running
`bin/plugin install cloud-aws` before (re)starting elasticsearch.
The following are a list of settings (prefixed with `gateway.s3`) that
can further control the S3 gateway:
[cols="<,<",options="header",]
|=======================================================================
|Setting |Description
|`chunk_size` |Big files are broken down into chunks (to overcome AWS 5g
limit and use concurrent snapshotting). Default set to `100m`.
|=======================================================================
[float]
==== concurrent_streams
The `gateway.s3.concurrent_streams` allow to throttle the number of
streams (per node) opened against the shared gateway performing the
snapshot operation. It defaults to `5`.
[float]
==== Region
The `cloud.aws.region` can be set to a region and will automatically use
the relevant settings for both `ec2` and `s3`. The available values are:
`us-east-1`, `us-west-1`, `ap-southeast-1`, `eu-west-1`.
