> 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
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: impala-iceberg
> Fix For: Impala 4.2.0
>
>
> 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
