Subject Re: Dynamic TTLs / limits still not working in 2.2 ?
Date Tue, 08 Mar 2016 14:19:12 GMT
Oh, I just realized I made a mistake with the TTL query:

The TTL has to be specified before the set. Like this:
update mytable using ttl :timetolive set data=:data where ts=:ts and
randkey=:randkey

And this of course works nicely. Sorry for the confusion.


Nevertheless, I don't think this is the issue with my "select ... limit"
querys. But I will verify this and also try the workaround.
