Jason Gerlowski commented on SOLR-16531:
----------------------------------------
bq. Honestly, It's disturbing when somebody says Sorry if I broke your
use-case, it's just your problem, but this new feature that I'm working on is
so important for everyone .
Yeah, if it helps reassure you more, that's absolutely NOT what I'm trying to
say. I want to get this fixed as much as you do. I've put tons of work into
JAX-RS/Jersey specifically and v2 in general - I want to make this as easy to
use and as fast as I can for everyone.
bq. As long as 9.2 is as performant as 9.1 it's good enough
I mentioned this on Slack but really should've raised this earlier here: but
there's already a workaround for the perf issue if you're not using the v2 API,
and that's to disable v2. With the right system property, 9.2-SNAPSHOT should
be "as performant as 9.1" today. And like I said, I'm very motivated to make
even that workaround unnecessary - though more hands and eyes are always
welcome.
