My understanding is only the block(s) that gets requested and read by any application will be flagged to stay in the most recently used side of the LRU buffer chains. Having the object marked as cache will not make Oracle to load the whole thing in memory and pin it there.

How much memory is consumed by cache tables? For example, if you have a small amount of data in a lookup table that's locally managed with 128K uniform extents, does it consume 128K of memory even if the data is only in one 8k DB block? (If that's the case then it would be better to assign it to a keep buffer pool.)
