Subject: [GENERAL] In memory Database for postgres
Hello,
I guess most of you guys heard about In Memory Database.I
have a small question regarding it.I need to create an In Memory
Database for postgresql through which I have to perform various
operations on postgresql database(queries,procedures,programs using
pqxx API etc...).I didn't have any idea of how to start and where to
start this issue.Please comment on this issue,so that it will be really
helpful to me .

If you have lots of memory on your system, PostgreSQL will hold the
frequently used tables in memory. So the burning question is:
What do you really want to do this for?
There are existing in memory database systems with a free license like
PostgreSQL:
FastDB:
http://www.garret.ru/databases.html
MonetDB:
http://monetdb.cwi.nl/
FastDB is an embedded, single writer - multiple reader type solution.
MonetDB is a column oriented database, especially suitable for database
warehouse designs.
There are additional solutions found in this article:
http://en.wikipedia.org/wiki/In-memory_database
Now, I think it would be very nice to have in-memory or column oriented
tables in PostgreSQL, but that would be a heavy-duty major difficult
project.
If you are volunteering to take that on, I suspect it is going to be
harder than you think, and if you want someone else to do it, I guess it
is not on the horizon yet.
