Specifies how Avro data should be formatted during an INSERT.

Data Type

bool

Default Value

false

Remarks

When set to false, the provider writes Avro data using standard Avro file blocks as defined in the Avro specification. This format allows multiple rows to be written into a single Kafka message and is more compact, but it is not compatible with Confluent tools or Confluent schema validation.

When set to true, the provider writes each row as a separate message using the Confluent Avro format. Enable this option if you rely on Confluent schema validation or need compatibility with Confluent serialization libraries.

This option cannot be enabled unless RegistryURL is set and points to a Confluent schema registry. AWS Glue registries do not support schema IDs, which are required by the Confluent Avro format.
