Do Not Allow Non-deterministic Functions in Mutations of Replicated Table Engines, Because This Can Introduce Inconsistencies Between Replicas

Official CH changelog text
Do not allow non-deterministic functions in mutations of Replicated table engines, because this can introduce inconsistencies between replicas. #7247 (Alexander Kazakov)
Disallow non-deterministic functions in mutations on Replicated table engines.

Why it matters

To prevent inconsistencies across replicas by blocking mutations that use non-deterministic functions, ensuring data integrity and consistency in replicated environments.

How to use it

Users should avoid including non-deterministic functions in mutation queries on Replicated table engines, as such mutations will now be rejected automatically to maintain replica consistency.
