## What is the purpose of the change In case of tables with deeply nested structures this issue with unnecessary String concatenations in the RexFieldAccess constructor started to play significant role and we faced it already. Since the fix ([CALCITE-5965](https://issues.apache.org/jira/browse/CALCITE-5965)) is only in Calcite 1.36.0 it can take a long time before it comes with Calcite upgrade (currently there are 1.33 and 1.34 in ready for review only) ## Brief change log There are 2 commits: 1. Copy paste of `RexFieldAccess` from (1.32.0) 2. Port fix from CALCITE-5965 ## Verifying this change to test it need to create a table with deeply nested columns and execute select. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): ( no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: ( no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): ( no ) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: ( no) - The S3 file system connector: ( no) ## Documentation - Does this pull request introduce a new feature?
