Background

In order to guide the creation of a reusable conditional sampling mechanism, we first need to understand how teams are currently implementing their own.

We need to:

1. Document existing conditional sampling mechanisms in code; and
2. Speak with Product Owners and Product Analysts about the need for such mechanisms
   • These conversations will be informed by the outcome of 1

AC

• Notes on existing conditional sampling are published on-wiki

Notes

1. https://codesearch.wmcloud.org/search/?q=mw%5C.eventLog%5C.%28event%7Cpageview%7Csession%29InSample&files=&excludeFiles=&repos= lists all of the uses of mw.eventLog.eventInSample(), .pageviewInSample(), and .sessionInSample(), which are convenience methods for implementing sampling mechanisms
