Add Avro Format Support for Maps and Records with Null Default Setting

Why it matters

This feature addresses limitations in handling complex Avro data structures by enabling the ingestion of Maps and Records, which were previously unsupported. The new setting improves data compatibility by allowing null values to be interpreted as default values, preventing import errors and making data processing more robust.

How to use it

To enable this feature, use the new setting input_format_avro_null_as_default when importing Avro data to treat null values as default. Maps and Records in Avro format are now supported transparently when ingested using the Avro input format.
