Method Detail

validateIndexName

public static void validateIndexName(java.lang.String index,
                                     ClusterState state)

Validate the name for an index against some static rules and a cluster state.

validateIndexOrAliasName

public static void validateIndexOrAliasName(java.lang.String index,
                                            java.util.function.BiFunction<java.lang.String,java.lang.String,? extends java.lang.RuntimeException> exceptionCtor)

Validate the name for an index or alias against some static rules.

createIndex

public void createIndex(CreateIndexClusterStateUpdateRequest request,
                        ActionListener<CreateIndexClusterStateUpdateResponse> listener)

Creates an index in the cluster state and waits for the specified number of shard copies to become active (as specified in CreateIndexClusterStateUpdateRequest.waitForActiveShards()) before sending the response on the listener. If the index creation was successfully applied on the cluster state, then ClusterStateUpdateResponse.isAcknowledged() will return true, otherwise it will return false and no waiting will occur for started shards (CreateIndexClusterStateUpdateResponse.isShardsAcked() will also be false). If the index creation in the cluster state was successful and the requisite shard copies were started before the timeout, then CreateIndexClusterStateUpdateResponse.isShardsAcked() will return true, otherwise if the operation timed out, then it will return false.

Parameters:

request - the index creation cluster state update request

listener - the listener on which to send the index creation cluster state update response

validateIndexSettings

public void validateIndexSettings(java.lang.String indexName,
                                  Settings settings)
                           throws IndexCreationException

Throws:

IndexCreationException
