Thanks for the detailed report — I’m trying to narrow this down to a minimal Spark 3.5 + Iceberg repro. Could you share: 1. A reduced `MERGE INTO` statement that still fails (including the `ON` clause and one `WHEN MATCHED` update clause) 2. The exact table schema pattern (for example, whether failing columns are nested/quoted/mixed-case) 3. Whether the same SQL fails against Spark + a non-Iceberg table format at similar width That would help confirm whether this is an Iceberg extension binding issue vs a Spark analyzer limit in wide merge plans. -- This is an automated message from the Apache Git Service.
