I am trying to divide the buffer pool into 5 parts and i call these clusters (different from postgres db clusters). What i want to do is to make a mapping from the relations to these clusters. One relation belongs to one cluster and a cluster can obviously have more than one relations. I use a hash table to do this similar to the buf_table.c file. Right now i don't know how many relations there are in total. I have just initialized it to 100. The key is relation and the data is the cluster information. Can anyone see any problems in using this approach. Feed back will be greatly appreciated.
PS i am aware that because of OS caching this may not cause any improvements. thanks nailah ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
