Class BatchExecutor

java.lang.Object

com.google.cloud.bigtable.hbase.BatchExecutor

All Implemented Interfaces:

AutoCloseable

@InternalApi(value="For internal usage only")
public class BatchExecutor
extends Object
implements AutoCloseable

Class to help BigtableTable with batch operations on an BigtableClient, such as Table.batch(List, Object[]). Table.put(List) and Table.get(List). This class relies on implementations found in BulkReadWrapper and in BigtableBufferedMutatorHelper.

For internal use only - public for technical reasons.
