Lazy/deferred schema support for
RecordBatchPullInputAdapterSummary
Makes the
schemaparameter optional inRecordBatchPullInputAdapter. Whenschema=None, the schema is extracted lazily from the first record batch at runtime via the PyCapsule C Data interface. This enables deferred iterator patterns where the data source isn't available untilcsp.run()is called.Thanks to @rjshs for the work on this.
