So using the values retrieved from the previous step, we can simplify the log by inserting it to each column like the information table below. Note that it takes time for logs to get from your system tables to your S3 buckets, so new events will only be available in your system tables (see the below section for that). It collects statistics about the data in a table, which can then be used by the query planner to generate more efficient query plans. as part of your cluster's parameter group definition.
