   First, you don’t need to include both `iceberg-core` and `iceberg-spark-runtime-3.2_2.12`. For Iceberg, the “Spark runtime” jar is the only dependency required (though you nigh need some non-Iceberg dependencies, such as AWS s3 Java SDK v2 to use S3FileIO). But `iceberg-core` is already included in the Spark runtime jar.
   
   Second, can you please provide the full output of `desc extended <tbl>`? I’m wondering if one of the columns has maybe been dropped, and so the query filter is being simplified to false because a non-null value is being provided.
   
   In any case, the `desc extended <tbl>` output, as well as the full logs from the deletion, would be beneficial.
   
   It’s also possible that one of the columns you marked is a partition column or something and that value isn’t present. Just a couple guesses, but the full logs as well as the `desc extended <tbl>` output would help a lot in debugging.
   
   Additionally, querying the current snapshot with that same filter to see if any data is returned (eg `select count(*) from tbl where <that deletion where clause>`) would also be beneficial in debugging.
