IIRC in EOF this was "probabilistic", with framework trying to guess which other objects' relationships to include in batch fetch. So we'd also need to track some kind of "affinity" of root objects between each other.
The first step would be to patch Cayenne to make org.apache.cayenne.reflect.FaultFactory injectable (currently it is created inside EntityResolver). Then come up with a custom FaultFactory and an algorithm for tracking the affinity of faults between each other. And make sure it doesn't leak memory :) Andrus > On Jul 6, 2016, at 12:20 AM, Mike Kienenberger <mkien...@gmail.com> wrote: > > That'd be something I'd get some use out of as well. > > On Tue, Jul 5, 2016 at 5:19 PM, Lon Varscsak <lon.varsc...@gmail.com> wrote: >> I know I’ve asked this before, but I need a batch fetch utility class, to >> trigger batch fetching of relationships.
