Get objects that will be peristed

[hg-ms]

thanks @hg-ms
do you think it might be of interest for you guys to incorporate some sort of a listener API for this inside the code?
I am thinking about potential use cases like outbox pattern, Change Data Capture integration etc...
this would be beneficial I think...

There is a way to get all objects that will be persisted, but it is a bit hacky:
To do so you need to create a storer and cast it to BinaryStorer.Default.
Between the store and commit you can retrieve all objects that will be persisted.

BinaryStorer.Default storer = (Default) storage.createLazyStorer();
storer.store(root);
storer.iterateMergeableEntries((oid, instance) -> {System.out.println("oid: " + oid + " instance: " + instance);} );
storer.commit();

This is not very user friendly, mybe we can add a more convenient API

vote + 1, the feature could be a good alternative for mongodb change stream.

Maybe we should consider adding a concept like the Hibernate interceptors.
