@steveburnett @agrawalreetika I've create an issue #26334 to track the future compression codec support. After checking with @ZacBlanco, he's happy to help review but probably do not have enough time to take PR #25021 all the way to merge. Will fork his work in #25021 into a new PR and drive it from there soon.
