Thanks, yeah, I understand that I couldn't truly consume from multiple threads. I was hoping I could get away with just commits from the thread (to signal that processing of the data it was passed was complete).
It's just a little extra complication. A SMOP. Skip On Dec 29, 2017 10:46 AM, "Stephen Durfey" <sjdur...@gmail.com> wrote: Hey Skip, the Kafka consumer is NOT thread safe. If you want to share across threads you will need to properly lock. Alternatively you can create a consumer per thread. Check out the class javadoc under the "multithreaded processing" for more details and suggestions. ________________________________ From: Skip Montanaro <skip.montan...@gmail.com> Sent: Friday, December 29, 2017 11:21:52 AM To: users@kafka.apache.org Subject: Can I commit from a thread? I subscribe to topics and receive input in my main thread (this happens to be in Python): consumer = kafka.KafkaConsumer(...) for data in consumer: do_stuff(data) do_stuff(...) can hand messages off to a separate thread for processing. Is it okay to call commit() from that thread or do I need to do the complete lock dance for that as well? Thanks, Skip Montanaro
