> The vectorized DELTA_BYTE_ARRAY Parquet decoder can cause read failures when
> reading columns with varying page encodings and if some pages are encoded
> using DELTA_BYTE_ARRAY.
> Same bug existed in parquet-mr reader but was fixed 3 months ago. There is no
> separate bug fix commit, it was silently fixed along with other changes.
