In general I don’t think how you deploy it impacts the behavior, just the performance ---- 2018-12-21 16:42:41 UTC - Grant Wu: > the function code will be uploaded to a Pulsar broker and run alongside the broker rather than in your local environment. seems to imply just one broker, but not clear ---- 2018-12-21 16:46:22 UTC - Shalin: Right, I was concerned about the performance part. Like if `broker B` is serving `topic 1` and the function `test` reads from `topic 1` but is deployed on `broker A`, it might not be ideal. thinking_face : Grant Wu ---- 2018-12-21 16:48:05 UTC - Shalin: But then again a function would be interacting with multiple topics served in different brokers, so not sure there could be locality aware deployment of functions. ---- 2018-12-21 17:02:03 UTC - Shalin: @Grant Wu: Did that make sense? or is that not how pulsar functions work ? ---- 2018-12-21 17:02:11 UTC - Grant Wu: Yeah it made sense ---- 2018-12-21 17:02:24 UTC - Grant Wu: You’ll have to wait for a response from a Pulsar dev :sweat_smile: ---- 2018-12-21 17:02:52 UTC - Shalin: Lol, gotcha. :thumbsup: ---- 2018-12-21 18:35:46 UTC - Sanjeev Kulkarni: @Shalin pulsar functions running in a pulsar cluster are distributed across all function workers in that cluster. The logic of which function instance goes to which worker is pluggable. The current logic just does a round robin assignment and thus is essentially random. However the mechanism is meant to be pluggable and we can have other assignment logic like scheduling functions closest to the broker that serves input/output topic. This is an area of active development ---- 2018-12-21 20:06:34 UTC - Michael Weedon: @Michael Weedon has joined the channel ---- 2018-12-21 20:43:04 UTC - Daniel Root: I'm trying to reduce the number of log messages produced by the standalone pulsar docker container. I've modified the log4j2.yaml file but can't figure out how to load the changes. If I restart the container my modifications are of course gone. How do I load these changes? Restart the cluster? If so how? I do have access to the admin-cli. ----
