Description

• The Parquet Reader creates a reusable bulk entry based on the column precision
• It uses the column precision for optimizing the intermediary heap buffers
• It first detected the column was fixed length but then it reverted this assumption when the column changed precision
• This step was fine except the bulk entry memory requirement changed though the code didn't update the bulk entry intermediary buffers
