Snapshot Changes should have a Streaming Interface #15659
Description
Feature Request / Improvement
Currently SnapshotChanges only provides a caching interface that eagerly materializes all file changes into in-memory lists and returns Iterable. There are use cases where returning a streaming CloseableIterable would be preferable see #13556 for example.
I think we probably should just add CloseableIterable interfaces to SnapshotChanges as well and just have the caching calls wrap them.
