> Hi, [@mbutrovich](https://github.com/mbutrovich) this should not be a large feature to implement, so we quickly fix it if necessary. What I want to confirm is that we should return null if identity-partitioned columns return null, right? Hey @liurenjie1024!, yep that's my understanding. I think we fell through into that scenario before #1824. ## Workaround in DataFusion Comet We're working around this in Comet by skipping `NULL` partition values during serialization and relying on the Iceberg spec rule 4 to correctly resolve missing fields as `NULL`: https://github.com/mbutrovich/datafusion-comet/blob/df51/spark/src/main/scala/org/apache/comet/serde/operator/CometIcebergNativeScan.scala#L391-L398 -- This is an automated message from the Apache Git Service.
