Обсуждение: Can postgresql be run in memory (like a memory resident program)
Is it possible to run post-gresql in memory? I searched through all the older postings didn't find much info. Thanks Ravi
What is it that you want to *do*? Like any program, while postgresql is running, parts of it are in memory. ap ---------------------------------------------------------------------- Andrew J Perrin - http://www.unc.edu/~aperrin Assistant Professor of Sociology, U of North Carolina, Chapel Hill clists@perrin.socsci.unc.edu * andrew_perrin (at) unc.edu On Tue, 25 Feb 2003, Malghan, Ravi wrote: > Is it possible to run post-gresql in memory?

You could create a RAM disk but one of the important directive a DB engine design is persistency.....since RAM is non-persistent, then you'll lose the content everytime you reboot.....is that OK ?

You could presumably mount the databases on an in-memory filesystem
such as the oft-available "tempfs", and thus have the data reside "in
memory."
But more realistically if this is what you /truly/ want, you should
probably look at other packages like FastDB or Speedy.
