    • individualAcknowledgeMessage

      public CompletableFuture<Void> individualAcknowledgeMessage(org.apache.pulsar.client.api.transaction.TxnID txnID, List<org.apache.commons.lang3.tuple.MutablePair<org.apache.bookkeeper.mledger.impl.PositionImpl,Integer>> positions)
      Description copied from interface: PendingAckHandle
      Acknowledge message(s) for an ongoing transaction.

      It can be of CommandAck.AckType.Individual. Single messages acked by ongoing transaction will be put in pending_ack state and only marked as deleted after transaction is committed.

      If transaction is aborted all messages acked by it will be put back to pending state.

      Client will not send batch size to server, we get the batch size from consumer pending ack. When we get the Batch size, we can accurate batch ack of this position.

      Specified by:
      individualAcknowledgeMessage in interface PendingAckHandle
      Parameters:
      txnID - TxnID TransactionID of an ongoing transaction trying to sck message.
      positions - MutablePair the pair of positions and these batch size.
      Returns:
      the future of this operation.

    • cumulativeAcknowledgeMessage

      public CompletableFuture<Void> cumulativeAcknowledgeMessage(org.apache.pulsar.client.api.transaction.TxnID txnID, List<org.apache.bookkeeper.mledger.impl.PositionImpl> positions)
      Description copied from interface: PendingAckHandle
      Acknowledge message(s) for an ongoing transaction.

      It can be of CommandAck.AckType.Cumulative. Single messages acked by ongoing transaction will be put in pending_ack state and only marked as deleted after transaction is committed.

      For a moment, we only allow one transaction cumulative ack multiple times when the position is greater than the old one.

      We have a transaction with cumulative ack, if other transaction want to cumulative ack, we will return TransactionConflictException.

      If an ongoing transaction cumulative acked a message and then try to ack single message which is greater than that one it cumulative acked, it'll succeed.

      Specified by:
      cumulativeAcknowledgeMessage in interface PendingAckHandle
      Parameters:
      txnID - TxnID TransactionID of an ongoing transaction trying to sck message.
      positions - MutablePair the pair of positions and these batch size.
      Returns:
      the future of this operation.
