Field Detail

REMOTE_CLUSTERS_SEEDS

public static final Setting.AffixSetting<java.util.List<java.net.InetSocketAddress>> REMOTE_CLUSTERS_SEEDS

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

REMOTE_CONNECTIONS_PER_CLUSTER

public static final Setting<java.lang.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_INITIAL_CONNECTION_TIMEOUT_SETTING

public static final Setting<TimeValue> REMOTE_INITIAL_CONNECTION_TIMEOUT_SETTING

The initial connect timeout for remote cluster connections

REMOTE_NODE_ATTRIBUTE

public static final Setting<java.lang.String> REMOTE_NODE_ATTRIBUTE

The name of a node attribute to select nodes that should be connected to in the remote cluster. For instance a node can be configured with node.attr.gateway: true in order to be eligible as a gateway node between clusters. In that case search.remote.node.attr: gateway can be used to filter out other nodes in the remote cluster. The value of the setting is expected to be a boolean, true for nodes that can become gateways, false otherwise.

ENABLE_REMOTE_CLUSTERS

public static final Setting<java.lang.Boolean> ENABLE_REMOTE_CLUSTERS

If true connecting to remote clusters is supported on this node. If false this node will not establish connections to any remote clusters configured. Search requests executed against this node (where this node is the coordinating node) will fail if remote cluster syntax is used as an index pattern. The default is true
