Local Gatewayedit

The local gateway module stores the cluster state and shard data across full cluster restarts.

The following static settings, which must be set on every data node in the cluster, controls how long nodes should wait before they try to recover any shards which are stored locally:

gateway.expected_nodes
The number of (data or master) nodes that are expected to be in the cluster. Recovery of local shards will start as soon as the expected number of nodes have joined the cluster. Defaults to 0
gateway.expected_master_nodes
The number of master nodes that are expected to be in the cluster. Recovery of local shards will start as soon as the expected number of master nodes have joined the cluster. Defaults to 0
gateway.expected_data_nodes
The number of data nodes that are expected to be in the cluster. Recovery of local shards will start as soon as the expected number of data nodes have joined the cluster. Defaults to 0
gateway.recover_after_time
If the expected number of nodes is not achieved, the recovery process waits for the configured amount of time before trying to recover regardless. Defaults to 5m if one of the expected_nodes settings is configured.

Once the recover_after_time duration has timed out, recovery will start as long as the following conditions are met:

gateway.recover_after_nodes
Recover as long as this many data or master nodes have joined the cluster.
gateway.recover_after_master_nodes
Recover as long as this many master nodes have joined the cluster.
gateway.recover_after_data_nodes
Recover as long as this many data nodes have joined the cluster.
Note

These settings only take effect on a full cluster restart.
