   I think adding a table level option to flag if the results of a scan should be cached or not would be a great way to help the cache from being polluted by queries that are scanning and returning a lot of single use data. It would be very useful for those tables that are scanned to satisfy user generated queries and scanned by applications to return a large collection of records that will be saved off for a data science research and development project. The latter query will often return a lot of records, take a long time to execute, and be executed vary rarely; so having a flag to indicate the such scan results should not be cached would ensure the cache maintains the results from the user generated queries.
