Thank you for working on that!
I'd like to mention some of my works. I think we can add the vacuum
performance improvements by the following commits:
- Add template for adaptive radix tree (ee1b30f1)
- Add TIDStore, to store sets of TIDs (ItemPointerData) efficiently (30e144287)
- Use TidStore for dead tuple TIDs storage during lazy vacuum (667e65aac)
Also, please consider the following item:
- Improve eviction algorithm in ReorderBuffer using max-heap for many
subtransactions (5bec1d6bc)
Finally, should we mention the following commit in the release note?
It's not a user-visible change but added a new regression test module.
- Add tests for XID wraparound (e255b646a)
