Hi guys, Thank you a lot for your answers. In fact, I tried to write the easiest explanation of my problem in order to be understood... My project is developed with Symfony and Doctrine (BERK, i know ...). The project has more than 2 years and Doctrine makes some bad decisions and lock all the table for a while. We are developing the project without Doctrine but it will not be available within 1 year... To be more precise : We have a database with more than 400 Gb and ONE table with more than 100 Gb of data. This is huge for doctrine. When the cron runs, it writes a lot on the disks in temporary file (although we have 128 GB of Ram...). Of course, each table is well indexes... That is why I'm thinking about replication : My server A (master) is for my users... and my server B is a server reserved for calculations (and this server B which writes on the base) This is a image of my dream system : <http://postgresql.nabble.com/file/n5855916/9e41ce1f-38ea-4fba-a437-a43c598e655c.jpg> (If you can't see the image : http://tof.canardpc.com/view/9e41ce1f-38ea-4fba-a437-a43c598e655c.jpg) Thank you a lot for your help ! -- View this message in context: http://postgresql.nabble.com/Which-replication-is-the-best-for-our-case-tp5855685p5855916.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
