> Key: IMPALA-11582
> URL: https://issues.apache.org/jira/browse/IMPALA-11582
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: impala-iceberg
>
> 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.
> See details at https://impala.apache.org/docs/build/html/topics/impala_tablesample.html
