Dmitriy,
There are some notes about WAL compaction in "Persistence Under the
Hood" article:
https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Persistent+Store+-+under+the+hood#IgnitePersistentStore-underthehood-WALcompaction
Please take a look - it has all the answers.
Best Regards,
Ivan Rakov

Folks,
I have a fix for a critical issue related to WAL compaction:
https://issues.apache.org/jira/browse/IGNITE-8393
In short, if part of WAL archive is broken, attempt to compress it may
result in spamming warnings in infinite loop.
I think it's also worth being included in 2.5 release.
Let's include it, especially given that the fix is done.
Ivan, on another note, is WAL compaction described anywhere? What do we do
internally to compact WAL and by what factor are we able to reduce the WAL
file size?
