Cybercluster 2.0 - Synchronous replication for PostgreSQL

Posted on 2010-05-18

Cybertec Schönig & Schönig GmbH, one of the

world's leading PostgreSQL companies, today announced the

availability of Cybercluster 2.0, a synchronous single-master replication solution

for PostgreSQL 9.0.

Cybercluster 2.0 is completely based on PostgreSQL's internal Write Ahead Log

(WAL) and thus offers highest possible performance at minimal overhead.

Cybercluster 2.0 will seaminglessly integrate into existing PostgreSQL

installations and it is 100% compatible with PostgreSQL 9.0.

How does it work?

Cybercluster 2.0 offer synchronous replication. This means that a transaction is

only marked as committed if it has safely been replicated to your entire

database cluster. There is no chance of losing a transaction anymore - even if a

database node in your cluster dies you can rely on the fact that no data can

ever be lost. Your cluster will always stay consistent and ready to serve your


Cybercluster 2.0 uses PostgreSQL's Write Ahead Log and efficiently streams data

to all nodes in the cluster. You can flexibily choose if you want to replicate

synchronously or asynchronously to an array or database slaves. You can even mix

synchronous and asynchronous replication - this guarantees unprecedented

flexibility, enhanced stability and superior replication performance.


Cybertec Schönig & Schönig GmbH provides full 24x7 support for Cybercluster 2.0

and offers a stable upgrade path to future versions of PostgreSQL.

Cybercluster can be used with all platforms which are known to work with

PostgreSQL 9.0. This includes but is not limited to Linux, Mac OS X, FreeBSD as

well as Microsoft Windows XP / Vista / 7.
