Development/Summer of Code/2017
Direct access to MusicBrainz database from CritiqueBrainz
Proposed mentor: Gentlecat
Languages/skills: Python, Flask, SQL (PostgreSQL, SQLAlchemy), Docker, Consul
So far, the biggest cause for slowdown in CritiqueBrainz are requests to MusicBrainz web service. It's not that MusicBrainz WS is slow, it's just that some pages on CritiqueBrainz require a lot of MusicBrainz data, which might take a very long time to retrieve. This can be caused by the complexity of a request, or by a number of them (when showing multiple items, since there's no way to do batch-requests).
New infrastructure allows us to easily read data directly from the MusicBrainz database. Doing this in CritiqueBrainz will probably be a significant speedup.
