dawidwys opened a new pull request #8017: [hotfix][table] Introduced UnresolvedFieldReference & ResolvedFieldReference expressions URL: https://github.com/apache/flink/pull/8017 ## What is the purpose of the change * Splits `FieldReferenceExpression` into `UnresolvedFieldReferenceExpression` and `FieldReferenceExpression`. The latter should use indices of input and field within input as a reference rather than simply always looking up field by name. Proper use of the FieldReferenceExpression is not part of this PR. ## Brief change log *(for example:)* - *The TaskInfo is stored in the blob store on job creation time as a persistent artifact* - *Deployments RPC transmits only the blob storage reference* - *TaskManagers retrieve the TaskInfo from the blob cache* ## Verifying this change This change is a trivial rework / code cleanup without any test coverage. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (**yes** / no) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
