Hi, This issue can be considered from two perspectives: storage layout and compatibility. 1.Iceberg typically uses a columnar storage format (such as Parquet or Avro), and data is stored in files according to the original `decimal(P,S)` layout. Modifying `P` without changing `S` may require rewriting the storage file. 2.Iceberg tables may be used by multiple systems or applications, and modifying `P` may affect compatibility with other systems because different systems may handle decimal types differently. Even if `S` remains unchanged, increasing `P` may break compatibility with data exchange and sharing with other systems. -- This is an automated message from the Apache Git Service.
