Hi,
I noticed high consumer speedup (>10x) when I do not acknowledge individual
messages but bunch of them at once. I use client acknowledge mode as in the
case of failure to correctly process the message I may lose it. Seeing message
more than once is not a (big) problem. Currently I consume with
MessageListener.onMessage() but this doesn't allow me to acknowledge batch of
messages - I do not know in advance when next message will come (if any) so the
messages might be in acquired state for long time. With
MessageConsumer.receive(timeout) I could read the messages and acknowledge
batch of them and in the case of timeout, acknowledge them too. What are
suggested values for timeout and batch size? Are there other options to check
and tune? The broker is C++ 0.18.
Thank you, Jan
