DECLARE(Bool, short_circuit_function_evaluation_for_nulls, true, R"(
Whether to enable short-circuit evaluation for rows with at least one null in arguments in functions where useDefaultImplementationForNulls() is true.
Allows to execute functions with Nullable arguments only on rows with non-NULL values in all arguments when ratio of NULL values in arguments exceeds short_circuit_function_evaluation_for_nulls_threshold. Applies only to functions that return NULL value for rows with at least one NULL value in arguments.
