Summary: Implement table sampling for Iceberg tables
Key: IMPALA-11582
URL: https://issues.apache.org/jira/browse/IMPALA-11582
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Zoltán Borók-Nagy
Currently Iceberg tables cannot be sampled.
We should allow table sampling for Iceberg tables in SELECT and COMPUTE STATS
statements.
Predicates in the WHERE clause should affect the results of table sampling
similarly to how legacy tables work (sampling is applied after static partition
pruning).
Make the operation repeatable via the REPEATABLE clause.
