@ovasileva to add sampling

Bucket yourself $.cookie('enwikimwuser-sessionId', 'a1') to not see it.
I haven't been able to verify the EventLogging is working correctly or whether we can test the data we collect. Looking at https://meta.wikimedia.org/wiki/Schema:RelatedArticles we only log the session id.. was that an oversight?

Note we can work out the bucket via a script that converts session id to bucket if necessary. Just open a new task for that analysis and give one of the developers a dump of the data you want to convert in csv format.

( we can run mw.experiments.getBucket( x, sessionId ); on each result )

WHOOO!!!!

@Jdlrobson - ok, now onto eventlogging - we're only logging the session id, meaning we're not logging the bucket?

@Jdlrobson - almost done! I wanted to double-check if we are currently running the schema on all users

We talked about this in standup today. We should be running the schema on all users but someone will need to check the database to see if this is actually working. That said, we should be clear what the hypothesis is that we are trying to measure and check that we can actually measure this with the limited schema we have.
