Check the query WHERE clause and consider using a cluster key if appropriate. the number of objects is less than the specified limit). ; For all other attributes, the values are defined by the deployment connection. Separate Query Workloads The Snowflake Database has no indexes to build, no statistics to capture or partitions to manage.
