Optimized Calculation for LowCardinality Data Types
Optimized calculation of expressions for LowCardinality data types. #3200Why it matters
This feature improves the performance of expressions involvingLowCardinality data types by optimizing how these expressions are calculated. It reduces computational overhead and speeds up query execution when using LowCardinality columns.How to use it
No special configuration is required. The optimization is applied automatically when expressions involveLowCardinality data types.
