alvarowolfx opened a new pull request, #421:
URL: https://github.com/apache/arrow-go/pull/421

   ### Rationale for this change
   The BigQuery Storage Write API now accepts Arrow data. But schema data and 
record batches needs to send separately. Right now the `ipc.NewWriter` writes 
the schema data to the output buffer, which makes it fail on the BigQuery side, 
as the first message is the schema. 
   
   See related discussion on 
https://github.com/googleapis/google-cloud-go/issues/12478
   
   ### What changes are included in this PR?
   Add `WithSchemalessOutput` option to allow configuring the `ipc.Writer` to 
skip writing schemas.
   
   ### Are these changes tested?
   Yes, tested with BigQuery Storage Write API. But will add local tests to it 
too.
   
   ### Are there any user-facing changes?
   Yes, `WithSchemalessOutput` will be a public available option to users.
