Hey,

This is the 15th weekly update from revision scoring team that we have sent to this mailing list.

New developments:

• We'll no longer unnecessarily load the models into memory on the web workers[1].

• We can now score multiple models against the same revision ID for (essentially) free[2].

• Our precaching system will take advantage of this to drop load by about 3X[3].

• Update wmflabs deploy repo for new version of ORES[4].

Documentation & maintenance:

• We completed deployment and maintenance docs for Wiki labels[5], which means we've now got complete docs for our systems[6].

• We implemented basic continuous integration tests for the ORES extension[7].

Downtime:

• We had a 1 hour long downtime while trying to deploy new code to ores.wikimedia.org[8].  We've filed two critical tasks for making sure we don't make the mistake again[9,10].

1. https://phabricator.wikimedia.org/T134606 - Score multiple models with the same cached dependencies

2. https://phabricator.wikimedia.org/T139407 - Don't load models into memory of web workers

3. https://phabricator.wikimedia.org/T141376 - Update precached to group requests by model
