=== Get snapshots response format is changed
|
|
It's possible to get snapshots from multiple repositories in one go. The response format has changed
|
|
and now contains separate response for each repository.
|
|
|
|
For example, requesting one snapshot from particular repository
|
|
|
|
[source,console]
|
|
-----------------------------------
|
|
GET _snapshot/repo1/snap1
|
|
-----------------------------------
|
|
// TEST[skip:no repo and snapshots are created]
|
|
|
|
produces the following response
|
|
|
|
[source,console-result]
|
|
-----------------------------------
|
|
{
|
|
"responses": [
|
|

==== Deprecated node level compress setting removed
|
|
|
|
For shared file system repositories (`"type": "fs"`), the node level setting `repositories.fs.compress` could
|
|
previously be used to enable compression for all shared file system repositories where `compress` was not specified.
|
|
The `repositories.fs.compress` setting has been removed.
|
|
|
|
Instead use the repository specific `compress` setting to enable compression. See <<modules-snapshots>> for information
|
|
on the `compress` setting.
|
|
|
|

|
|
==== Compression of meta data files is now on by default
|
|
|
|
Previously, the default value for `compress` was `false`. The default has been changed to `true`.
|
|
|
|
This change will affect both newly created repositories and existing repositories where `compress=false` has not been
|
|
explicitly specified.
|
|
|
|
For more information on the compress option, see <<modules-snapshots>>

==== The S3 repository plugin uses the DNS style access pattern by default
|
|
|
|
Starting in version 7.4 the `repository-s3` plugin does not use the
|
|
now-deprecated path-style access pattern by default. In versions 7.0, 7.1, 7.2
|
|
and 7.3 the `repository-s3` plugin always used the path-style access pattern.
|
|
This is a breaking change for deployments that only support path-style access
|
|
but which are recognized as supporting DNS-style access by the AWS SDK. If your
|
|
deployment only supports path-style access and is affected by this change then
|
|
you must configure the S3 client setting `path_style_access` to `true`. This
|
|
breaking change was made necessary by
|
|
https://aws.amazon.com/blogs/aws/amazon-s3-path-deprecation-plan-the-rest-of-the-story/[AWS's
|
|
announcement] that the path-style access pattern is deprecated and will be
|
|
unsupported on buckets created after September 30th 2020.
