I just missed the call, but I watched the recording (thank you to Andrew
for posting [1]). Really interesting!
I'm diving into Arrow because I have some previous experience with
in-memory query engines. I'm following discussions around improving
performance and adding features so I can determine ho
I agree that OpenTelemetry is the future; I have been following the
observability space off and on and I knew about OpenTracing; I just realized
that OpenTelemetry is its successor. [1]
I have found tracing to be a very powerful approach; at one point, I did a POC

I know a lot about the general subject of grouping, although this was in a
closed-source framework I created which also uses columnar in-memory data; it
was specific to Java but at its heart it has a lot in common with Arrow.

I've been mostly lurking for awhile, but I would like to start picking off some
bugs in the Java implementation.In the process of slogging through the build,
I've bumped into various issues. I'm happy to document them in java/README.md
or make any other changes that might be helpful to others. I
I'd like to introduce myself, because I've had an interest in Arrow for a long
time and now I have a chance to help out.Up until now, I haven't really
contributed much in open source, although I've been an avid consumer, so I'd
