Class SSTableTxnWriter

java.lang.Object

org.apache.cassandra.utils.concurrent.Transactional.AbstractTransactional

org.apache.cassandra.io.sstable.SSTableTxnWriter

All Implemented Interfaces:

java.lang.AutoCloseable, Transactional

public class SSTableTxnWriter
extends Transactional.AbstractTransactional
implements Transactional

A wrapper for SSTableWriter and LifecycleTransaction to be used when the writer is the only participant in the transaction and therefore it can safely own the transaction.
