Hi!
It looks like all the issues that we have had with Blazegraph 2.0 are now fixed, so I will attempt to upgrade our install to 2.0 again sometime around noon PDT tomorrow. There should be no visible changes except for brief restart for each server that should not be externally visible (since we have two so the other one would just take over). However, if something bad happens, there might be a brief disruption of service.
I'll send a message when it's done, and if you notice anything weird after the upgrade, please ping me or submit issue in Phabricator.
Thanks,
Hi!
The upgrade is now done and query.wikidata.org is running on Blazegraph 2.0. If you notice something wrong please tell me or file an issue in Phabricator.
Thanks,
So, is there an equivalent for WDQ "AROUND[]" now? :-)

Not yet :) I.e., we could simulate it by accessing longitude/latitude manually, but in order to use BG 2.0's geospatial index, we need to add code to specifically encode our coordinate literals in a way compatible with this index. So there's still work to do, see https://phabricator.wikimedia.org/T123565 There are some interesting challenges due to the fact that our coordinates include globes which is not a very common thing, but we're working on supporting it.
