Migrate Parsoid from legacy to new storage
Closed, ResolvedPublic
Actions

Description

Migrate Parsoid (incl. stashing) from legacy storage (Cassandra 2.x), to the new strategy and cluster (Cassandra 3.x). This is planned to happen in two steps, first all non-Wikipedia groups, then the Wikipedias. Between these two steps, cluster reshaping will occur, with capacity decommissioned from the legacy cluster, and bootstrapped into the new.

All but WPs (and the global domain, technically) have been switched to use the new storage schema with Cassandra 3. We need to keep the old contents around for the next 24h, though, before we can get rid of the data in Cassandra 2. data tables in the following keyspaces can be truncated (not dropped!) after that period elapses:

All but the default group tables have been truncated. default still had activity due to the wikidata.org domain which had not been switched. We switched that one too, so we should be able to truncate that group tomorrow as well.

We are now ready to switch the WP Parsoid tables to Cassandra 3. I propose to do a coordinated deploy of Parsoid (bumping the HTML content version to 1.6.0) and RESTBase (moving to Cassandra 3) on Tuesday, 2017-12-12 during the regular services deploy window. Specifically, we need to:

  • prepare the bump of the Parsoid and MCS versions in RESTBase
  • prepare the storage switch to Cassandra 3 in RESTBase
  • deploy Parsoid
  • deploy MCS
  • deploy RESTBase
  • start HTML dumps for at least the biggest WPs to minimise client impact of the deployment

Furthermore, for RESTBase we need to ensure the transition period of 24h during which contents is read from both new and old storage to avoid edit failures.

Just in case others are confused like I was, RB is assuming a very generous 24-hour visual editor session, i.e. a VE edit session is started before deploy and is active upto 24 hours after deploy. They want to ensure that a save at any point in that 24+ hour period does the right thing by fetching data-parsoid from cassandra-2 for the HTML that was fetched from cassandra-2 before deploy.

I hope that means that RB picks the latest one of the two.

The storage back-end has been switched. I started dumps of en, de, fr, it and es WPs in a screen session on praseodymium targeting restbase.svc.codfw.wmnet. Once they are done, we need to merge and deploy PR #920 at which point this task can be considered done.

I had to stop them because they were hammering Cassandra 3 too much. We'll start them slowly and consecutively at a later point, probably tomorrow.
