Re: [PR] [core] Augment scan projection with column-mask input columns [paimon]

JingsongLi commented on PR #8570:
URL: https://github.com/apache/paimon/pull/8570#issuecomment-4953813568

   - This PR addresses the projection of cross-column masks but explicitly does not handle the original value filtering/partition pruning/min-max/TopN/limit pushdown for masked columns.
   - The results may be filtered by pre-desensitized values, reveal whether original values exist, or discard rows due to errors.
   - The author has specifically addressed this issue in Draft #8582. It is recommended that Pull Request #8570 not be merged separately but at least processed in conjunction with #8582.
