Class RetryError

  • All Implemented Interfaces:
    Serializable

    public class RetryError
    extends ControlFlowError
    A ControlFlowError thrown when an explicit retry is done on a Txn. With the {RetryError} it is possible to create blocking transactions.

    An example is a transaction wants to pop an item from an empty queue. The Retry is caught by the transaction handling logic (e.g the TxnExecutor and blocks until either a timeout happens or an item is placed on the queue.
