Package: wnpp Severity: wishlist * Package name : Postgres-XC Version : 0.9.6 Upstream Author : Koichi Suzuki * URL : http://postgres-xc.sourceforge.net/ * License : (BSD) Programming Lang: (C) Description : write-scalable, synchronous multi-master, transparent PostgreSQL cluster It is a collection if tightly coupled database components which can be installed in more than one hardware or virtual machines. . Write-scalable means Postgres-XC can be configured with as many database servers as you want and handle many more writes (updating SQL statements) compared to what a single database server can not do. . Multi-master means you can have more than one database server that clients connect to which provide a single, consistent cluster-wide view of the database. . Synchronous means any database update from any database server is immediately visible to any other transactions running on different masters. . Transparent means you (and your applications) do not have to worry about how your data is stored in more than one database servers internally. . You can configure Postgres-XC to run on multiple servers. Your data is stored in a distributed way, that is, partitioned or replicated, as chosen by you for each table. When you issue queries, Postgres-XC determines where the target data is stored and issues corresponding queries to servers containing the target data.
