> I don't understand what this needs from `native_iceberg_compat`. Collation sequences are needed for sort. Is the requirement to ensure that the Spark type does not drop the collation information during the scan? I really don't know yet. For now, we just want to fall back to Spark for any queries where the schema has string collation types and the scan is the first place where we see this. It has been a while since I started looking into this, but IIRC, I was getting errors in the scan when converting the Spark schema to the Arrow schema because we did not recognize the string collation types. -- This is an automated message from the Apache Git Service.
