docMapper

protected DocumentMapperForType docMapper(String type)

recoveryFromSnapshot

public int recoveryFromSnapshot(Engine engine,
                                Translog.Snapshot snapshot)
                         throws IOException

例外:

IOException

performRecoveryOperation

public void performRecoveryOperation(Engine engine,
                                     Translog.Operation operation,
                                     boolean allowMappingUpdates)

Performs a single recovery operation.

パラメータ:

allowMappingUpdates - true if mapping update should be accepted (but collected). Setting it to false will cause a MapperException to be thrown if an update is encountered.

operationProcessed

protected void operationProcessed()

Called once for every processed operation by this recovery performer. This can be used to get progress information on the translog execution.

getRecoveredTypes

public Map<String,Mapping> getRecoveredTypes()

Returns the recovered types modifying the mapping during the recovery
