Hey,
The last release introduced SQLStore3, a partial rewrite of SQLStore2,
improving on the performance of its predecessor. That is not the end of the
story for the SMW query stores though.
This email was prompted by work MWJames is doing in supporting MongoDB \o/
https://gerrit.wikimedia.org/r/#/c/88534/
For a while now, there have been two items on our Roadmap about utilizing
new libraries I created for the Wikidata project, that are both based on,
and usable by, SMW components.
* https://semantic-mediawiki.org/wiki/Roadmap#Make_use_of_DataValues_library
* https://semantic-mediawiki.org/wiki/Roadmap#Make_use_of_Ask_library
There now is a third such component, which might enable us to get a nice
improvement to our SQLStore without all to much effort. I described this
here:
https://semantic-mediawiki.org/wiki/Wikibase_QueryEngine
This is still quite far off, assuming no one else jumps on it, given that
it requires the earlier two items to be finished first. Feedback on the
idea is however welcome. And awareness of these preliminary plans, or
rather possibilities (I'm not committed to doing this at this point), is
good for those doing or planning to do something related to the SMW storage
infrastructure.
Cheers
