> 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.
