> Honour Iceberg sort orders when writing a table
> -----------------------------------------------
>
> Key: IMPALA-11428
> URL: https://issues.apache.org/jira/browse/IMPALA-11428
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Reporter: Zoltán Borók-Nagy
> Assignee: Daniel Becker
> Priority: Major
> Labels: impala-iceberg
>
> Iceberg specification defines {{{}sort orders{}}}. We should consider this
> when writing to an Iceberg table through Impala.
> See: [https://iceberg.apache.org/spec/#sort-orders]
> Currently we only add Iceberg partition expressions during INSERTs:
> [https://github.com/apache/impala/blob/26438d8e3e2cecfdab82643fcee7553df50198ca/fe/src/main/java/org/apache/impala/analysis/InsertStmt.java#L866]
> Impala's SORT BY clauses always sort the files in ascending order, Iceberg
> allows more control over it.
