Class ProcedureStoreTracker

java.lang.Object

org.apache.hadoop.hbase.procedure2.store.ProcedureStoreTracker

@InterfaceAudience.Private
 @InterfaceStability.Evolving
public class ProcedureStoreTracker
extends Object

Keeps track of live procedures. It can be used by the ProcedureStore to identify which procedures are already deleted/completed to avoid the deserialization step on restart

Method Detail

resetToProto

public void resetToProto(org.apache.hadoop.hbase.shaded.protobuf.generated.ProcedureProtos.ProcedureStoreTracker trackerProtoBuf)

resetTo

public void resetTo(ProcedureStoreTracker tracker)

Resets internal state to same as given tracker. Does deep copy of the bitmap.

resetTo

public void resetTo(ProcedureStoreTracker tracker,
                    boolean resetDelete)

insert

public void insert(long procId)

insert

public void insert(long[] procIds)

insert

public void insert(long procId,
                   long[] subProcIds)

update

public void update(long procId)

delete

public void delete(long procId)

delete

public void delete(long[] procIds)

setDeleted

@InterfaceAudience.Private
public void setDeleted(long procId,
                                                  boolean isDeleted)

setDeletedIfSet

public void setDeletedIfSet(long... procId)

setDeletedIfSet

public void setDeletedIfSet(ProcedureStoreTracker tracker)

getUpdatedMinProcId

public long getUpdatedMinProcId()

getUpdatedMaxProcId

public long getUpdatedMaxProcId()

reset

public void reset()

isUpdated

public boolean isUpdated(long procId)

isDeleted

public ProcedureStoreTracker.DeleteState isDeleted(long procId)

If partial is false, returns state from the bitmap. If no state is found for procId, returns YES. If partial is true, tracker doesn't have complete view of system state, so it returns MAYBE if there is no update for the procedure or if it doesn't have a state in bitmap. Otherwise, returns state from the bitmap.

getActiveMinProcId

public long getActiveMinProcId()

setKeepDeletes

public void setKeepDeletes(boolean keepDeletes)

isPartial

public boolean isPartial()

setPartialFlag

public void setPartialFlag(boolean isPartial)

isEmpty

public boolean isEmpty()

Returns:

true, if no procedure is active, else false.

isUpdated

public boolean isUpdated()

Returns:

true if any procedure was updated since last call to resetUpdates().

resetUpdates

public void resetUpdates()

Clears the list of updated procedure ids. This doesn't affect global list of active procedure ids.

undeleteAll

public void undeleteAll()

dump

public void dump()

toProto

public org.apache.hadoop.hbase.shaded.protobuf.generated.ProcedureProtos.ProcedureStoreTracker toProto()
                                                                                                throws IOException

Builds org.apache.hadoop.hbase.protobuf.generated.ProcedureProtos.ProcedureStoreTracker protocol buffer from current state.

Throws:

IOException
