Thanks for the issue, we should definitely support more kinds of objects to the backends' insert method:

I think the full set of possible options is this (not sure if we want to implement them all without someone asking for them first)

• Arrow tables
• Single Arrow record batches
• Sequences of Arrow record batches
• Arrow record batch readers

@ianmcook Do you mind if we consolidate on #8133?
