Discovery/Status updates/Next

This is the weekly update for the week starting 2019-03-04

Highlights

 * Something goes here

Search

 * We've updated Textcat with the new Russian wrong-keyboard and wrong-encoding models and now need CirrusSearch to be up to date as well
 * In order to ease migration to ES6 we should migrate to 5.6.14 first (epic task is now completed)
 * As part of the ES6 update, we needed to upgrade logstash and the logstash elasticsearch cluster to 5.6.14
 * We also upgraded logstash plugin to 5.6.14 as part of the prep for elasticsearch upgrade
 * We've deployed & tested WikibaseCirrusSearch on beta cluster
 * We've also deployed & tested WikibaseCirrusSearch on testwikidata and found things to be good!
 * We found that incigna monitoring for Elasticsearch doesn't seem to notice when an out-of-memory error has happened on a node — this will be fully fixed with the next cluster restart
 * There was some logspam due to deduplicating I18N messages between Wikibase and WikibaseCirrusSearch that we resolved
 * A discovery was made with a WMFTimeoutException in Special:Search that was resolved by decreasing timeouts and removing our timeout hack for regexes
 * An umbrella task to track patches of merge commits to activate elastic6 support code
 * A ticket created way back in 2016 asked: 'the new substring search is great on mw.o. Can we have it on office wiki too?' and yes, now it is

Wikidata Query Service

 * We've created CI testing environment for Blazegraph on our Jenkins CI
 * Working on hiring a contractor to help us with Blazegraph tasks
 * We noticed that metrics from wdqs updater JMX should be prefixed while we were investigating something else, metrics exposed by jmx_exporter running on wdqs-updater should be prefixed with wdqs_updater_ to make it more clear what they are referring to (done!)
