Hi;
I am trying to determine if there is anything I can do with MySQL that I can't do with PostgreSQL. HEAP tables are the last one I can't figure out.
HEAP tables are MySQL tables which reside in memory and are visible across sessions. For obvious reasons, this violates the D in ACID.
In many cases this can be very usefull-- for example if I am building a system where I want the simplicity of a SQL-like interface with the low latency of memory-only devices. WOuld I have to run the entire db in a ramdisk, or can anyone think of a way to do something like this?
It has occurred to me that when table spaces are supported, then this would be much easier (have a HEAP table space sitting on a ramdisk).
If your table is that small, you could just cache it in your application.
