We are testing in memory postgres database and have questions about configuring the ram mount point and whether there is great gains in setting it up this way? Are there any considerations for postgres? If you have experience, can you please give us some ideas on how you have accomplished this?
you might look into TimesTen... Oracle bought them a couple years ago, they have an SQL database thats heavily optimized for memory rather than block oriented disk. it optionally uses a disk as a persistence backing store. Of course, the entire database has to fit in ram, and they charge proportional to database size. its extremely fast.
