Beautiful, thank you very much! From: Jonathan Haddad [mailto:j...@jonhaddad.com] Sent: Thursday, March 14, 2019 4:55 PM To: user <user@cassandra.apache.org> Subject: Re: To Repair or Not to Repair
My coworker Alex (from The Last Pickle) wrote an in depth blog post on TWCS. We recommend not running repair on tables that use TWCS. http://thelastpickle.com/blog/2016/12/08/TWCS-part1.html It's enough of a problem that we added a feature into Reaper to auto-blacklist TWCS / DTCS tables from being repaired, we wrote about it here: http://thelastpickle.com/blog/2019/02/15/reaper-1_4-released.html Hope this helps!

Has anyone else had a similar experience? Wondering if running TWCS is doing more harm than good as it chews up a lot of cpu and for extended periods of time in comparison to CF’s with a compaction strategy of STCS Thanks, -- Jon Haddad http://www.rustyrazorblade.com twitter: rustyrazorblade
