Failure: On accessing an external Iceberg table that have parquet file in version 2, the SELECT * FROM … statement fails with error message: “Not supported: Not supported page type: 3”.
Release: 3.4.2, and 3.5.2-69de616
The page type 3 in the error message refers to the Data Page V2 (see apache arrow: arrow/cpp/src/generated/parquet_types.h at main · apache/arrow · GitHub ).
In comparison, The query success when accessing another iceberg table that only uses parquet v1 (i.e. without data page V2).
This failure was known for earlier releases that did not have parquet DataPage V2 support then. However, this feature has been added to the code base few month ago (Apr 10, 2025): [Enhancement] support parquet data page v2(no encoding) by dirtysalt · Pull Request #57621 · StarRocks/starrocks · GitHub
Because we are not able to force this source Iceberg table to be created/saved in parquet v1, therefore, the Data Page V2 support from Starrocks is critical. Giving the fact that this feature is already in the code base for a few months, we wonder whether it is already or going to be available in a release? which one?
Thanks!
