There are mysql lock less sessions mentioned on wiki:
“a new version of Sessions which works in no-locking mode”
https://rt-wiki.bestpractical.com/wiki/LockLessSessionsMySQL
What are benefits and, more importantly, disadvantages for this?
wiki sadly is sparse about this mode.
(my primary problem with rt is that when mysql full text query is happening (and sometimes it can take ages like 10 minutes) then I’m unable to do anything else because my session is locked; I wonder if lockless session would help me)
