Interface BackoffPolicy

  • All Known Implementing Classes:
    DefaultBackoffPolicy

    public interface BackoffPolicy
    A policy to be used when Txn or an atomic operation can't make any progress, e.g. because there a ReadWriteConflict. If the next attempt would be done without waiting, the contention is going to increase. It can be better to back off to give the contending Transactions some time to complete so that the chance increases that the failing Txn can complete at a next attempt. Of course when there is a lot of contention, the BackoffPolicy isn't going to help and the Txn could start to suffer from a livelock/starvation.
