Method Details

write

public Iterator<ConditionalWriter.Result> write(Iterator<ConditionalMutation> mutations)

Description copied from interface: ConditionalWriter

This method returns one result for each mutation passed to it. This method is thread safe. Multiple threads can safely use a single conditional writer. Sharing a conditional writer between multiple threads may result in batching of request to tablet servers.

Specified by:

write in interface ConditionalWriter

Returns:

Result for each mutation submitted. The mutations may still be processing in the background when this method returns, if so the iterator will block.

getConfig

public ConditionalWriterConfig getConfig()

write

public ConditionalWriter.Result write(ConditionalMutation mutation)

Description copied from interface: ConditionalWriter

This method has the same thread safety guarantees as ConditionalWriter.write(Iterator)

Specified by:

write in interface ConditionalWriter

Returns:

Result for the submitted mutation

close

public void close()

Description copied from interface: ConditionalWriter

release any resources (like threads pools) used by conditional writer

Specified by:

close in interface AutoCloseable

Specified by:

close in interface ConditionalWriter
