Class TransportAddIndexBlockAction

public class TransportAddIndexBlockAction extends TransportMasterNodeAction<AddIndexBlockRequest,AddIndexBlockResponse>
Adds a single index level block to a given set of indices. Not only does it set the correct setting, but it ensures that, in case of a write block, once successfully returning to the user, all shards of the index are properly accounting for the block, for instance, when adding a write block all in-flight writes to an index have been completed prior to the response being returned. These actions are done in multiple cluster state updates (at least two). See also TransportVerifyShardIndexBlockAction for the eventual delegation for shard-level verification.
