… map RecordBatch between schemas (apache#19716) I've now seen this pattern a couple of times, in our own codebase, working on apache/datafusion-comet#3047. I was going to add an example but I think adding an API to handle it for users is a better experience. This should also make it a bit easier to migrate from SchemaAdapter. In fact, I think it's possible to implement a SchemaAdapter using this as the foundation + some shim code. This won't be available in DF 51 to ease migration but it's easy enough to backport (just copy the code in this PR) for users that would find that helpful.
