Nicolas,
I don't believe we've had any discussions recently about revisiting the
database indexing/SQL queries. In fact we had intended to focus more on
performance improvements in the 3.6 release, but the collectively, the
committers didn't have time/resources to do the profiling and refactoring that
would have required. I think the most recent development around the SQL queries
was when we switched everything to use prepared statements, but that was quite
some time ago.
If you've made fixes and are able to contribute them back, please submit pull
requests to fcrepo:
https://github.com/fcrepo/fcrepo
(of course we love pull requests that include test coverage =))
If you're able, please join us on the next committers call (Thursday 9am
Eastern) to talk about what we could focus on improving for the next release.
Of course on-list is fine too, but if you want a higher-bandwidth discussion,
please join the call:
