Package org.apache.pulsar.client.impl.transaction

Class TransactionImpl

  • All Implemented Interfaces:
    io.netty.util.TimerTask, org.apache.pulsar.client.api.transaction.Transaction
    public class TransactionImpl
extends java.lang.Object
implements org.apache.pulsar.client.api.transaction.Transaction, io.netty.util.TimerTask
    The default implementation of Transaction.

    All the error handling and retry logic are handled by this class. The original pulsar client doesn't handle any transaction logic. It is only responsible for sending the messages and acknowledgements carrying the transaction id and retrying on failures. This decouples the transactional operations from non-transactional operations as much as possible.
