             Summary: Add conflictDetectionFilter for Iceberg DML statements
                 Key: IMPALA-12568
                 URL: https://issues.apache.org/jira/browse/IMPALA-12568
             Project: IMPALA
          Issue Type: Bug
            Reporter: Zoltán Borók-Nagy


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.
