Greetings,
I have been inspired by a recent work on logging and recovery[1], and found that our WALs could be further compacted to reduce disk space usage and I/O. If you are interested in WAL or related issues, please have a look at the corresponding Jira issue[2] and discuss about your idea within this thread, thanks a lot.
