usmanm / redis-tdigest Goto Github PK

It is hard to build images with this package because there are no releases or git tags. Can we have such?

(I'd of course be happy to send PRs to do this -- just making sure you agree, checking if you have a preference for releasing or "just" tagging, and whether you have preference for an initial version number!)

Our redis instance running with tdigest module got coredump in every 4-5 days.
gdb provides backtrace as below.
Could you please take a look at it?
Tks.
