Class ShardStateAwareRemoteCollector

java.lang.Object

io.crate.execution.engine.collect.collectors.ShardStateAwareRemoteCollector

All Implemented Interfaces:

CrateCollector

public class ShardStateAwareRemoteCollector
extends java.lang.Object
implements CrateCollector

This component will collect data from a remote node when the provided shard is not available on the local node due to a relocation. In case the cluster state does not yet reflect the fact that the target shard was relocated (ie. it is closed locally but it's routing status is still RELOCATING) it will wait for the shard to get started and then start collecting (remote collecting in case the shard relocated to a different node or a local collection if the shard ended up back on the local node)
