Class KeyValueLocator

java.lang.Object

com.couchbase.client.core.node.locate.KeyValueLocator

All Implemented Interfaces:

Locator

public class KeyValueLocator
extends Object
implements Locator

This Locator finds the proper Nodes for every incoming BinaryRequest.

Depending on the bucket type used, it either uses partition/vbucket (couchbase) or ketama (memcache) hashing. For broadcast-type operations, it will return all suitable nodes without hashing by key.

Since:

1.0.0
