@shangxinli, I wouldn't expect an alias map when getting a schema from that path. If you're parsing the schema from Iceberg metadata, then there are no aliases. We only set them when the schema is created by converting a Parquet MessageType to Iceberg Schema. When converting to the Parquet FilterApi, the aliases must come from a Schema instance that was created from the MessageType of the file you're pushing filters to. Otherwise, the aliases might not match the file because the file may have been written with different column names. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
