Delete auto-follow patterns. Delete a collection of cross-cluster replication auto-follow patterns.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :name (String) —

    The auto-follow pattern collection to delete. (Required)

  • :master_timeout (Time) —

    The period to wait for a connection to the master node. If the master node is not available before the timeout expires, the request fails and returns an error. It can also be set to -1 to indicate that the request should never timeout. Server default: 30s.

#follow(arguments = {}) ⇒ Object

Create a follower. Create a cross-cluster replication follower index that follows a specific leader index. When the API returns, the follower index exists and cross-cluster replication starts replicating operations from the leader index to the follower index.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :index (String) —

    The name of the follower index. (Required)

  • :master_timeout (Time) —

    Period to wait for a connection to the master node. Server default: 30s.

  • :wait_for_active_shards (Integer, String) —

    Specifies the number of shards to wait on being active before responding. This defaults to waiting on none of the shards to be active. A shard must be restored from the leader index before being active. Restoring a follower shard requires transferring all the remote Lucene segment files to the follower index.

  • :headers (Hash) —

    Custom HTTP headers

  • :body (Hash) —

    request body

Raises:

  • (ArgumentError)

#forget_follower(arguments = {}) ⇒ Object

Forget a follower. Remove the cross-cluster replication follower retention leases from the leader. A following index takes out retention leases on its leader index. These leases are used to increase the likelihood that the shards of the leader index retain the history of operations that the shards of the following index need to run replication. When a follower index is converted to a regular index by the unfollow API (either by directly calling the API or by index lifecycle management tasks), these leases are removed. However, removal of the leases can fail, for example when the remote cluster containing the leader index is unavailable. While the leases will eventually expire on their own, their extended existence can cause the leader index to hold more history than necessary and prevent index lifecycle management from performing some operations on the leader index. This API exists to enable manually removing the leases when the unfollow API is unable to do so. NOTE: This API does not stop replication by a following index. If you use this API with a follower index that is still actively following, the following index will add back retention leases on the leader. The only purpose of this API is to handle the case of failure to remove the following retention leases after the unfollow API is invoked.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :index (String) —

    the name of the leader index for which specified follower retention leases should be removed (Required)

  • :timeout (Time) —

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error. Server default: 30s.

  • :headers (Hash) —

    Custom HTTP headers

  • :body (Hash) —

    request body

Raises:

  • (ArgumentError)

Parameters:

    a customizable set of options

Options Hash (arguments):

#pause_auto_follow_pattern(arguments = {}) ⇒ Object

Pause an auto-follow pattern. Pause a cross-cluster replication auto-follow pattern. When the API returns, the auto-follow pattern is inactive. New indices that are created on the remote cluster and match the auto-follow patterns are ignored. You can resume auto-following with the resume auto-follow pattern API. When it resumes, the auto-follow pattern is active again and automatically configures follower indices for newly created indices on the remote cluster that match its patterns. Remote indices that were created while the pattern was paused will also be followed, unless they have been deleted or closed in the interim.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :name (String) —

    The name of the auto-follow pattern to pause. (Required)

  • :master_timeout (Time) —

    The period to wait for a connection to the master node. If the master node is not available before the timeout expires, the request fails and returns an error. It can also be set to -1 to indicate that the request should never timeout. Server default: 30s.

#put_auto_follow_pattern(arguments = {}) ⇒ Object

Create or update auto-follow patterns. Create a collection of cross-cluster replication auto-follow patterns for a remote cluster. Newly created indices on the remote cluster that match any of the patterns are automatically configured as follower indices. Indices on the remote cluster that were created before the auto-follow pattern was created will not be auto-followed even if they match the pattern. This API can also be used to update auto-follow patterns. NOTE: Follower indices that were configured automatically before updating an auto-follow pattern will remain unchanged even if they do not match against the new patterns.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :name (String) —

    The name of the collection of auto-follow patterns. (Required)

  • :master_timeout (Time) —

Resume an auto-follow pattern. Resume a cross-cluster replication auto-follow pattern that was paused.

#resume_follow(arguments = {}) ⇒ Object

    a customizable set of options

Options Hash (arguments):

  • :index (String) —

    The name of the follow index to resume following. (Required)

#unfollow(arguments = {}) ⇒ Object

Unfollow an index. Convert a cross-cluster replication follower index to a regular index. The API stops the following task associated with a follower index and removes index metadata and settings associated with cross-cluster replication. The follower index must be paused and closed before you call the unfollow API.

Parameters:

  • arguments (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (arguments):

  • :index (String) —

    The name of the follower index. (Required)

  • :master_timeout (Time) —

    The period to wait for a connection to the master node. If the master node is not available before the timeout expires, the request fails and returns an error. It can also be set to -1 to indicate that the request should never timeout. Server default: 30s.

  • :headers (Hash) —

    Custom HTTP headers

Raises:

  • (ArgumentError)
