Jason Gerlowski commented on SOLR-17192:
----------------------------------------
I can't say I'm always consistent on this, but I usually go with alphabetical
order (by first name) - that way I stay out of the business of sizing
contributions altogether :-p
I'm open to doing things a different way if there's consensus on reading
additional semantics into CHANGES.txt, but if so, maybe it should be written up
and documented in 'dev-docs/' or in Confluence first?
(I'm replying from my phone or I'd just modify CHANGES.txt now. If I forget to
do it later, feel free to make whatever changes you'd like to the attribution!)

> Solr isn't infinitely scalable when it comes to the number of fields in each
> core/collection. Most deployments start to experience problems any time a
> core has upwards of a few hundred fields. Usually this doesn't exhibit
> itself right away. instead waiting until segment-merge or some other time to
> rear its head.
> Sometimes users hit this through intentional schema design. Often however,
> it happens "accidentally" due to (mis-)use of Solr's "dynamic fields" feature.
> We should add a configurable soft-limit, of the type described in SOLR-17191,
> to prevent users from unknowingly getting into this state.
