*Cybercluster 2.0
Synchronous single-master replication for the masses*

Vienna, May 18th 2010: 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 
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.
