In the Optimizing Plan phase, it is necessary to obtain the file's PartitionSpec. However, calling `getMixedTablePartitionSpecById` in a loop is a very expensive and unnecessary operation。 https://github.com/apache/amoro/blob/678b43c85347eb69d61e4f7ca016cb63d2ae56e4/amoro-ams/src/main/java/org/apache/amoro/server/optimizing/plan/OptimizingEvaluator.java#L119-L124 Especially in environments where Kerberos is enabled, repeatedly calling `org.apache.iceberg.BaseTable#specs` can incur lock overhead. - [ ] ### How should we improve? I want to place the code for obtaining PartitionSpec inside the TableFileScanHelper interface。 ```java ... PartitionSpec partitionSpec = tableFileScanHelper.getSpec(fileScanResult.file().specId()); ... ``` ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Subtasks _No response_ ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
