| PackageDescription | write-scalable, synchronous multi-master, transparent PostgreSQL cluster
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. |
