Parents with more than 50K children can't participate in some rollup styles #1490
Description
Is your feature request related to a problem? Please describe.
If a parent record has more than 50K children then SOQL often can't produce the aggregate result necessary to calculate the rollup. SOQL has a hard limit on rows read during a transaction.
Describe the solution you'd like
It would be nice if DLRS could be smart enough to break the rollup calculation into chunks in extreme cases, processing a single parent in batches. Not sure how to do that safely and for which rollup styles it will be compatible.
Describe alternatives you've considered
Because this is a hard limit in Apex I don't know how to handle this in a single transaction so I don't know of any workarounds.
Additional context
This would be tricky to test and review. Takes a bit of work to stage an environment with enough records to do this but not outside of the storage capabilities. Should build test scenarios using Snowfakery.
