Add a new field condition to system
Added a new fieldconditionto system tablesystem.query_condition_cache. It stores the plaintext condition whose hash is used as a key in the query condition cache. #78671 (Robert Schulze).
Why it matters
This feature enhances the visibility of cached query conditions by providing the actual condition text stored under the hash key. It helps users understand and debug query condition caching more effectively.How to use it
Query thesystem.query_condition_cache system table to see the newly available condition field which contains the plaintext condition for each cached entry. For example: SELECT condition FROM system.query_condition_cache.
