[GitHub] [iceberg] gszadovszky opened a new issue #2546: Dictionary filter for Parquet does not handle FIXED_LEN_BYTE_ARRAY
gszadovszky opened a new issue #2546:
URL: https://github.com/apache/iceberg/issues/2546
If a Parquet file contains dictionary encoded `FIXED_LEN_BYTE_ARRAY` values (e.g. `DECIMAL`s) the related filtering throws an `IllegalArgumentException: Cannot decode dictionary of type: FIXED_LEN_BYTE_ARRAY`. I guess the library is not prepared for dictionary encoded `FIXED_LEN_BYTE_ARRAY` values because parquet-mr does not write such encoding for these values (for V1 at least) but it is not a specified behavior so other implementations (like Impala) may write them.
