Discovery Weekly Update for the week starting 2019-04-08

Chris Koerner-2

This is the weekly update from the Search Platform team for the week
starting 2019-04-08.

As always, feedback and questions are welcome.

== Discussions ==

=== Search ===
* New WikibaseCirrusSearch code is deployed and enabled on all wikis,
including Wikidata & Commons. [0]
*We re-indexed all Greek, Turkish, and Irish-language wikis with
better handling of Greek accents [1], Turkish İ/ı [2], and Irish
initial mutation [3] when lowercasing searches in quotes. [4]
* We noticed that indices can move to readonly state when disk space
is low and needs to be reset manually once disk space is available
again, so we made it a cookbook [5]
* David wrote a patch to help with an exception from
CirrusSearch/Sanity/Checker (cannot fetch ids from index) [6]
* We fixed/finalized more things with the ES6 upgrade:
** Create checks that alerts on cirrussearch update lags [7]
** Elasticsearch 6: the classic similarity is deprecated [8]
** Setup elasticsearch on cloudelastic100[1-4] [9]
** Rack/setup/install cloudelastic100[1-4].eqiad.wmnet systems [10]
* Erik converted mjolnir from KafkaRDD to direct kafka-python usage,
because KafkaRDD in pyspark only supports the 0.8 api [11]

=== Wikidata Query Service ===
* Deployed patch to fix an issue in Blazegraph workbench [12]
* Working on improving cache behavior of Updater [13]
