SEARCH_REMOTE_CLUSTERS_SEEDS

public static final Setting.AffixSetting<List<String>> SEARCH_REMOTE_CLUSTERS_SEEDS

SEARCH_REMOTE_CLUSTER_SEEDS_UPGRADER

public static final SettingUpgrader<List<String>> SEARCH_REMOTE_CLUSTER_SEEDS_UPGRADER

REMOTE_CLUSTER_SEEDS

public static final Setting.AffixSetting<List<String>> REMOTE_CLUSTER_SEEDS

A list of initial seed nodes to discover eligible nodes from the remote cluster

SEARCH_REMOTE_CLUSTERS_PROXY

public static final Setting.AffixSetting<String> SEARCH_REMOTE_CLUSTERS_PROXY

REMOTE_CLUSTERS_PROXY

public static final Setting.AffixSetting<String> REMOTE_CLUSTERS_PROXY

A proxy address for the remote cluster. By default this is not set, meaning that Elasticsearch will connect directly to the nodes in the remote cluster using their publish addresses. If this setting is set to an IP address or hostname then Elasticsearch will connect to the nodes in the remote cluster using this address instead. Use of this setting is not recommended and it is deliberately undocumented as it does not work well with all proxies.

SEARCH_REMOTE_CONNECTIONS_PER_CLUSTER

public static final Setting<Integer> SEARCH_REMOTE_CONNECTIONS_PER_CLUSTER

REMOTE_CONNECTIONS_PER_CLUSTER

public static final Setting<Integer> REMOTE_CONNECTIONS_PER_CLUSTER

The maximum number of connections that will be established to a remote cluster. For instance if there is only a single seed node, other nodes will be discovered up to the given number of nodes in this setting. The default is 3.

REMOTE_NODE_CONNECTIONS

public static final Setting.AffixSetting<Integer> REMOTE_NODE_CONNECTIONS

The maximum number of node connections that will be established to a remote cluster. For instance if there is only a single seed node, other nodes will be discovered up to the given number of nodes in this setting. The default is 3.
