I have done some chaos testing as well as ingestion testing 3-4 times on the recent 2.4 versions, each spanning the duration of around 8-10 hr. And also tested rolling upgrade from 1.6 to 2.4 a couple of times after applying the recent fixes on adding missing CFs in meta table as part of the upgrade. (Upgrade requires upgrading all RS first before masters)
Things seem to be running well so far, no significant concerns have been identified with default configs so far. Andrew and I will keep testing this release line on different infrastructure with different tooling, but for now, I have sufficient test data to provide my +1 for moving the stable pointers to 2.4. And thank you for starting this thread, Sean!
