Not so easy I think.

Most DBMS have such caches. And such parameters.

Big FBMS have even few caches, and may be future we also will.
For example, they separate DataCache and IndexCache.


DBMS always must be considered as system which work with DATA FILE which is
MANY MANY MANY times bigger of RAM, so you cannot allow to DBMS self
allocate more and more. You see?
