2020-07-20 20:16:26 UTC - Devin G. Bost: Does anyone know where in the code I'd find the behavior of auto-ack?
I'm trying to get a better understanding of when messages get acknowledged when auto-ack is enabled.

2020-07-20 20:25:10 UTC - Addison Higham: are you referring to functions auto ack? it is implemented by the runtime. `org/apache/pulsar/functions/instance/JavaInstanceRunnable.java:431` for the exactly-once, at least-once cases, and `org/apache/pulsar/functions/instance/JavaInstanceRunnable.java:257` for at-most-once
