Noemi Pap-Takacs updated IMPALA-12568:
--------------------------------------
Issue Type: Improvement (was: Bug)
> Add conflictDetectionFilter for Iceberg DML statements
> ------------------------------------------------------
>
> Key: IMPALA-12568
> URL: https://issues.apache.org/jira/browse/IMPALA-12568
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Zoltán Borók-Nagy
> Priority: Major
> Labels: impala-iceberg
>
> Currently Impala is too rigorous when it checks for conflicting data or
> delete files.
> Currently any concurrently added data/delete file conflict with the current
> DML operation, even if they touch different partitions.
> Iceberg has
> [conflictDetectionFilter|https://iceberg.apache.org/javadoc/1.0.0/org/apache/iceberg/RowDelta.html#conflictDetectionFilter-org.apache.iceberg.expressions.Expression-]([Expression|https://iceberg.apache.org/javadoc/1.0.0/org/apache/iceberg/expressions/Expression.html]
> conflictDetectionFilter) API to relax this. I.e. we could only check for
> conflicting data/delete files that are in partitions that the current DML
> operation touches.
> This way we could e.g. compact a partition while other partitions are being
> written.
