> If a query is going to read data that is likely going to fill or exceed the block cache size, then it is probably prudent to not cache the data at all. This way the query won't have to incur the cost of allocating and disposing of memory it or subsequent queries likely won't use. It would leave the block cache available to other queries that could really use it.
