Hi, as there were several questions about increasing performance in dwh systems I was looking for some hints about how to "pin" an object to the buffer so that they are not aged out due to the space is needed by any other process or object. I know that in oracle you can do this by defining a seperate buffer cache and to asign an object to that special buffer cache. So you could assign objects to one pool and all other objects will use the default one. I think even count(*) queries could benefit from this buffer-splitting due to indexes might be pinned to this buffer pool. So my question is if there is already any comparable functionality or if it is planed. I didn't find any comparable feature or TODO on the list.
