Interface ConditionalWriter

All Superinterfaces:
AutoCloseable

public interface ConditionalWriter extends AutoCloseable
ConditionalWriter provides the ability to do efficient, atomic read-modify-write operations on rows. These operations are performed on the tablet server while a row lock is held.
Since:
1.6.0
  • Method Details

    • write

      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.
      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.
    • write

      This method has the same thread safety guarantees as write(Iterator)
      Returns:
      Result for the submitted mutation
    • close

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