Re: [PERFORM] TB-sized databases

2007-11-26 Thread Stephen Cook 
I think either would work; both PostgreSQL and MS SQL Server have 
success stories out there running VLDBs.  It really depends on what you 
know and what you have.  If you have a lot of experience with Postgres 
running on Linux, and not much with SQL Server on Windows, of course the 
former would be a better choice for you.  You stand a much better chance 
working with tools you know.

I had a client that tried to use Ms Sql Server to run a 500Gb+ database. 
The database simply colapsed. They switched to Teradata and it is 
running good. This database has now 1.5Tb+.


Currently I have clients using postgresql huge databases and they are 
happy. In one client's database the biggest table has 237Gb+ (only 1 
table!) and postgresql run the database without problem using 
partitioning, triggers and rules (using postgresql 8.2.5).

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.

Re: [PERFORM] FUSION-IO io cards

Hi,
Had a recent conversation with a tech from this company called
FUSION-IO. They sell
  io cards designed to replace conventional disks.  The cards can be up
to 3 TB in size and apparently
are installed in closer proximity to the CPU than the disks are.  They claim
performance boosts several times better than the spinning disks.

Just wondering if anyone has had any experience with this company and these
cards.  We're currently at postgres 8.3.11.

Any insights / recommendations appreciated.  thank you,


Well, The Woz works there. Not because he needs money, but because he 
thinks they are doing it right.
