l.s.f.s.UserSliceScope(ScopeWithPerson) : class documentation

Part of lp.services.features.scopes View In Hierarchy

Selects a slice of all users based on their id.

Written as 'userslice:a,b' with 0<=a<b will slice the entire user population into b approximately equal sub-populations, and then take the a'th zero-based index.

For example, to test a new feature for 1% of users, and a different version of it for a different 1% you can use userslice:10,100 and userslice:20,100`.

You may wish to avoid using the same a or b for different rules so that some users don't have all the fun by being in eg 0,100.
