There is an open request to folk writing applications or layers that desire predicate pushdown to please add their use case and requirements to https://forums.foundationdb.org/t/feature-request-predicate-pushdown/954/2 , to help guide what the eventual implementation of this feature will be. If someone wouldn’t mind adding what Mango would need or desire, it’d be much appreciated.
