java.lang.Object
  org.apache.cassandra.service.RepairCallback

All Implemented Interfaces:

IAsyncCallback, IMessageCallback

public class RepairCallback
extends java.lang.Object
implements IAsyncCallback

Field Summary

protected java.util.concurrent.atomic.AtomicInteger	received
RowRepairResolver	resolver

Constructor Summary

RepairCallback(RowRepairResolver resolver, java.util.List<java.net.InetAddress> endpoints)
The main difference between this and ReadCallback is, ReadCallback has a ConsistencyLevel it needs to achieve.

Constructor Detail

RepairCallback

public RepairCallback(RowRepairResolver resolver,
                      java.util.List<java.net.InetAddress> endpoints)

The main difference between this and ReadCallback is, ReadCallback has a ConsistencyLevel it needs to achieve. Repair on the other hand is happy to repair whoever replies within the timeout. (The other main difference of course is, this is only created once we know we have a digest mismatch, and we're going to do full-data reads from everyone -- that is, this is the final stage in the read process.)

Method Detail

get

public Row get()
        throws java.util.concurrent.TimeoutException,
               DigestMismatchException,
               java.io.IOException

Throws:

java.util.concurrent.TimeoutException

DigestMismatchException

java.io.IOException

response

public void response(Message message)

Specified by:

response in interface IAsyncCallback

Parameters:

message - response received.

isLatencyForSnitch

public boolean isLatencyForSnitch()

Specified by:

isLatencyForSnitch in interface IMessageCallback

Returns:

true if this callback is on the read path and its latency should be given as input to the dynamic snitch.

getMaxLiveColumns

public int getMaxLiveColumns()
