Hi all, I’d like to discuss the versioning of the parquet shared libs that are built when you use -DARROW_PARQUET=ON. My observation is that back when parquet-cpp was a separate project the shared libs were versioned using the parquet-cpp version number (e.g 1.4.0). Since moving to a single repo, the parquet shared libraries are now versioned with the arrow version number (e.g. 0.12.0)
I assumed this wasn't carried over to the mono-repo and opened a JIRA [1] and a PR [2] to version the parquet shared libraries separately from Arrow. I've read through the thread discussing the mono-repo [3] and otherwise can't find mention of Wes' comment that: "I had thought we had discussed using the same SO version for all shared libraries produced by a particular build. Let's discuss this some more." I see some value in maintaining the parquet library version but equally see value in matching the arrow version. I'm not sure this is correct, but I still consider parquet-cpp somewhat separate (it has its own JIRA). An additional proposal is that we could modify the CREATED_BY_VERSION [4] to reference the Arrow version number for additional traceability with Parquet files written using the mono-repo. Any additional thoughts or a link to prior discussion on shared lib versioning would be much appreciated. Thanks!
