I found the bug and this problem only affects OSS.
Since you can modify and rebuild the files.
Add the following:
BooleanValidator EXCLUDE_INCREMENTAL_ICEBERG =
new BooleanValidator(
"reflections.planning.exclude.file_based_incremental.iceberg.accelerations", true);
To:
Rebuild that jar and you should be good. The issue is that the option cannot be found here: dremio-oss/services/accelerator/src/main/java/com/dremio/service/reflection/refresh/RefreshHandler.java at master · dremio/dremio-oss · GitHub
I’ve logged a bug internally to fix this.
