Change subject: IMPALA-6625: Skip computing parquet conjuncts for non-Parquet scans ...................................................................... IMPALA-6625: Skip computing parquet conjuncts for non-Parquet scans This change ensures that the planner computes parquet conjuncts only when for scans containing parquet files. Additionally, it also handles PARQUET_DICTIONARY_FILTERING and PARQUET_READ_STATISTICS query options in the planner. Testing was carried out independently on parquet and non-parquet scans: 1. Parquet scans were tested via the existing parquet-filtering planner test. Additionally, a new test [parquet-filtering-disabled] was added to ensure that the explain plan generated skips parquet predicates based on the query options. 2. Non-parquet scans were tested manually to ensure that the functions to compute parquet conjucts were not invoked. Additional test cases were added to the parquet-filtering planner test to scan non parquet tables and ensure that the plans do not contain conjuncts based on parquet statistics. 3. A parquet partition was added to the alltypesmixedformat table in the functional database. Planner tests were added to ensure that Parquet conjuncts are constructed only when the Parquet partition is included in the query.
