Hi all,
I have a user who is looking to store 500+ GB of data in a database
(and when all the indexes and metadata are factored in, it's going to
be more like 3-4 TB). He is wondering how well PostgreSQL scales with
TB-sized databases and what can be done to help optimize them (mostly
hardware and config parameters, maybe a little advocacy). I can't
speak on that since I don't have any DBs approaching that size.
The other part of this puzzle is that he's torn between MS SQL Server
(running on Windows and unsupported by us) and PostgreSQL (running on
Linux...which we would fully support). If any of you have ideas of how
well PostgreSQL compares to SQL Server, especially in TB-sized
databases, that would be much appreciated.
We're running PG 8.2.5, by the way.
Well I can't speak to MS SQL-Server because all of our clients run
PostgreSQL ;).. I can tell you we have many that are in the 500GB -
1.5TB range.
All perform admirably as long as you have the hardware behind it and are
doing correct table structuring (such as table partitioning).
Sincerely,
Joshua D. Drake
Peter
