Package org.apache.bookkeeper.client

Class PendingWriteLacOp

java.lang.Object

org.apache.bookkeeper.client.PendingWriteLacOp

All Implemented Interfaces:

BookkeeperInternalCallbacks.WriteLacCallback

class PendingWriteLacOp
extends java.lang.Object
implements BookkeeperInternalCallbacks.WriteLacCallback

This represents a pending WriteLac operation. When it has got success from Ack Quorum bookies, sends success back to the application, otherwise failure is sent back to the caller.

This is an optional protocol operations to facilitate tailing readers to be up to date with the writer. This is best effort to get latest LAC from bookies, and doesn't affect the correctness of the protocol.
