Change subject: IMPALA-11582: Implement table sampling for Iceberg tables ...................................................................... IMPALA-11582: Implement table sampling for Iceberg tables This patch adds table sampling functionalities for Iceberg tables. >From now it's possible to execute SELECT and COMPUTE STATS statements with table sampling. Predicates in the WHERE clause affect the results of table sampling similarly to how legacy tables work (sampling is applied after static partition and file pruning). Sampling is repeatable via the REPEATABLE clause.
