Limit a sync expression to a maximum number of records

[adplant]

Description

When creating a sync expression for DataStore it seems that the only things you can do to prevent the app from syncing the entire model's database is to do a query predicate that:

1. acts more like a chained filtering system (ex: all records where author = 'someauthor' and in the last 7 days) => which is nice, but still doesn't guarantee you won't be syncing more records for that model than you'd like to
2. id = null => to completely disregard syncing that model (also a nice feature, but not what I'm looking for).

I want to be able to place a limit on the number of records that will sync (at a maximum) on a per model basis.

This is mainly for performance issues, where I want to guarantee an approximate maximum wait time before the app is synced.

This is a feature request.
