Describe the enhancement requested

Right now RecordBatchReader infers schema based on the first batch. As a consequence, if any cell in the remaining stream does not comply to the schema fetching the data fails. It would be great to have an option to infer schema for each individual chunk instead of failing.

This is split from #17278.
