> I pushed another commit hiding the WithSchemalessOutput option and actually adding a NewRecordBatchWriter, which is the end goal: have a writer that emits only RecordBatch messages. Let me know if you have any other thoughts on that. I'll take a look in a bit and get back with my thoughts. > On the BigQuery side, the argument is that indeed we are only suppose to send RecordBatches, as receiving a schema trigger some logic to check if there is any change to the table schema, which is a mechanism that also exists when using the protobuf format. This mechanism is expensive and should be avoided when possible. Why is the schema verification expensive? Also, wouldn't you still need to run the same logic to check for changes to the table schema upon receiving the first RecordBatch? How does avoiding the Schema message allow you to avoid validating the schema? -- This is an automated message from the Apache Git Service.
