In yesterday's sprint planning meeting for Search, with a lot of guidance from Erik, I organised a bunch of tasks related to our quarterly goal to upgrade to Elasticsearch 2.3. This email summarises these tasks.
The overarching epic is T133120 https://phabricator.wikimedia.org/T133120 "Upgrade Wikimedia search cluster to use Elasticsearch 2.3". There are a lot of subtasks of this epic; take a look at the task description and blocking tasks for more information. This epic blocks T133119 https://phabricator.wikimedia.org/T133119 "Upgrade completion suggester so that its index updates in real time", which is the second part of the goal.
Hopefully, everything should be clear and organised. I've laid all the tasks out in the "This Quarter" of the new discovery-search-backlog project https://phabricator.wikimedia.org/tag/discovery-search-backlog/. Let me know if there are any questions, and I'd be happy to answer them.
Thanks!
Dan
