Thanks for the review. I pushed 2c30c5762e with the suite changes above.
`CometInMemoryCacheSuite` now gets its zstd codec from
`CometCachedBatchHelper.compressionCodec("zstd")`, so all four places that
built Arrow's codec directly go through `CometZstdCompressionCodec`. I also
rewrapped a comment in `CachedBatchIpc` that was one character over the
scalastyle limit.
On Spark having the same exposure: agreed, I read the 19.0.0 bytecode and
`ArrowCompressionUtils` and `ArrowCachedBatchSerializer` both build
`ZstdCompressionCodec` directly (`ArrowCompressionUtils` is also on
`branch-4.1` with Arrow 18.3.0). I'll file the SPARK JIRA soon and will comment
here once it's filed.
