Local gateway settings

edit

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

The following static settings, which must be set on every master-eligible node, control how long a freshly elected master should wait before it tries to recover the cluster state and the cluster’s data.

These settings only take effect during a full cluster restart.

gateway.expected_data_nodes
(Static) Number of data nodes expected in the cluster. Recovery of local shards begins when the expected number of data nodes join the cluster. Defaults to 0.
gateway.recover_after_time

(Static) If the expected number of nodes is not achieved, the recovery process waits for the configured amount of time before trying to recover. Defaults to 5m.

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

gateway.recover_after_data_nodes
(Static) Recover as long as this many data nodes have joined the cluster.

These settings can be configured in elasticsearch.yml as follows:

gateway.expected_data_nodes: 3
gateway.recover_after_time: 600s
gateway.recover_after_data_nodes: 3
