[erlang-questions] Inspecting db_hash_slot locks with lcnt
Fri Nov 15 14:36:16 CET 2013
I got acquainted with Lcnt not far ago and found it a really great tool.
While digging into the performance problems with the application i noticed
that by mistake one of the highly used ets did not have concurrency options
turned on for writes.
It was rather easy to find it by simply inspecting lcnt:inspect(db_tab) as
it shows on which tables this lock appear. But what a pity I could not find
any information on which etss
db_hash_slot appear. db_hash_slot's ids are common integers and as i
understand there is no way to find out on wich table they arise.
Is it just a lack of functionality, or I just missed something in the
I can see the same picture with some others lock classes as well.
