Class TransactionAwareHTable

java.lang.Object

co.cask.tephra.AbstractTransactionAwareTable

co.cask.tephra.hbase98.TransactionAwareHTable

All Implemented Interfaces:

TransactionAware, Closeable, AutoCloseable, org.apache.hadoop.hbase.client.HTableInterface

public class TransactionAwareHTable
extends AbstractTransactionAwareTable
implements org.apache.hadoop.hbase.client.HTableInterface, TransactionAware

A Transaction Aware HTable implementation for HBase 0.98. Operations are committed as usual, but upon a failed or aborted transaction, they are rolled back to the state before the transaction was started.
