optimize_min_equality_disjunction_chain_length
The minimum length of the expressionexpr = x1 OR ... expr = xN for optimization
optimize_min_inequality_conjunction_chain_length
The minimum length of the expressionexpr <> x1 AND ... expr <> xN for optimization
optimize_min_max_from_files
Enables or disables computingmin and max of columns from the statistics stored in data files instead of reading the data, for queries whose only aggregate functions are min and max of table columns, without GROUP BY and without filters. It applies to the table function/engine file with the Parquet format (not to files inside archives), for integer (up to 64 bits), date, date-time and decimal columns whose column chunk statistics are present in every row group.
Possible values:
- 0 - Optimization disabled.
- 1 - Optimization enabled.
