Re: [PERFORM] PostgreSQL clustering VS MySQL clustering

[Dave Cramer]

Two way xeon's are as fast as a single opteron, 150M rows isn't a big deal. Clustering isn't really the solution, I fail to see how clustering actually helps since it has to slow down file access.

I mean, forget the PostgreSQL (or any other database) restrictions and explain us how this hardware would be. Where the data would be stored? I've something in mind for you, but first I need to understand your needs! I just want to make a big database as explained in my first mail ... At the beginning we will have aprox. 150 000 000 records ... each month we will add about 4/8 millions new rows in constant flow during the day ... and in same time web users will access to the database in order to read those data. Stored data are quite close to data stored by google ... (we are not making a google clone ... just a lot of data many small values and some big ones ... that's why I'm comparing with google for data storage). Then we will have a search engine searching into those data ... Dealing about the hardware, for the moment we have only a bi-pentium Xeon 2.8Ghz with 4 Gb of RAM ... and we saw we had bad performance results ... so we are thinking about a new solution with maybe several servers (server design may vary from one to other) ... to get a kind of cluster to get better performance ... Am I clear ? Regards, -- Dave Cramer http://www.postgresintl.com 519 939 0336 ICQ#14675561
