Class HRegion.ReplayBatchOperation

java.lang.Object

org.apache.hadoop.hbase.regionserver.HRegion.BatchOperation<WALSplitUtil.MutationReplay>

org.apache.hadoop.hbase.regionserver.HRegion.ReplayBatchOperation

Enclosing class:

HRegion

@Deprecated
private static final class HRegion.ReplayBatchOperation
extends HRegion.BatchOperation<WALSplitUtil.MutationReplay>

Deprecated.

Since 3.0.0, will be removed in 4.0.0. Now we will not use this operation to apply edits at secondary replica side.

Batch of mutations for replay. Base class is shared with HRegion.MutationBatchOperation as most of the logic is same.

Throws:

IOException

checkAndPrepare

public void checkAndPrepare()
                     throws IOException

Deprecated.

Description copied from class: HRegion.BatchOperation

Validates each mutation and prepares a batch for write. If necessary (non-replay case), runs CP prePut()/preDelete()/preIncrement()/preAppend() hooks for all mutations in a batch. This is intended to operate on entire batch and will be called from outside of class to check and prepare batch. This can be implemented by calling helper method HRegion.BatchOperation.checkAndPrepareMutation(int, long) in a 'for' loop over mutations.

Specified by:

checkAndPrepare in class HRegion.BatchOperation<WALSplitUtil.MutationReplay>

Throws:

IOException
