prepareForTranslogOperations
public void prepareForTranslogOperations(boolean fileBasedRecovery, int totalTranslogOps) throws java.io.IOException
Description copied from interface:RecoveryTargetHandler
Prepares the target to receive translog operations, after all file have been copied- Specified by:
prepareForTranslogOperations
in interfaceRecoveryTargetHandler
- Parameters:
fileBasedRecovery
- whether or not this call is part of an file based recoverytotalTranslogOps
- total translog operations expected to be sent- Throws:
java.io.IOException
-
finalizeRecovery
public void finalizeRecovery(long globalCheckpoint)
Description copied from interface:RecoveryTargetHandler
The finalize request refreshes the engine now that new segments are available, enables garbage collection of tombstone files, and updates the global checkpoint.- Specified by:
finalizeRecovery
in interfaceRecoveryTargetHandler
- Parameters:
globalCheckpoint
- the global checkpoint on the recovery source
-
ensureClusterStateVersion
public void ensureClusterStateVersion(long clusterStateVersion)
Description copied from interface:RecoveryTargetHandler
Blockingly waits for cluster state with at least clusterStateVersion to be available- Specified by:
ensureClusterStateVersion
in interfaceRecoveryTargetHandler
-
handoffPrimaryContext
public void handoffPrimaryContext(ReplicationTracker.PrimaryContext primaryContext)
Description copied from interface:RecoveryTargetHandler
Handoff the primary context between the relocation source and the relocation target.- Specified by:
handoffPrimaryContext
in interfaceRecoveryTargetHandler
- Parameters:
primaryContext
- the primary context from the relocation source
-
indexTranslogOperations
public long indexTranslogOperations(java.util.List<Translog.Operation> operations, int totalTranslogOps, long maxSeenAutoIdTimestampOnPrimary, long maxSeqNoOfDeletesOrUpdatesOnPrimary)
Description copied from interface:RecoveryTargetHandler
Index a set of translog operations on the target- Specified by:
indexTranslogOperations
in interfaceRecoveryTargetHandler
- Parameters:
operations
- operations to indextotalTranslogOps
- current number of total operations expected to be indexedmaxSeenAutoIdTimestampOnPrimary
- the maximum auto_id_timestamp of all append-only requests processed by the primary shardmaxSeqNoOfDeletesOrUpdatesOnPrimary
- the max seq_no of update operations (index operations overwrite Lucene) or delete ops on the primary shard when capturing these operations. This value is at least as high as the max_seq_no_of_updates on the primary was when any of these ops were processed on it.- Returns:
- the local checkpoint on the target shard
-
receiveFileInfo
