SchoonerSQL

There is a product out in the wild which is called SchoonerSQL [ 1 ] from an American company called Schooner Information Technology [ 2 ]. They claim to have top-performance [ 3 ] and high-availability features with up 99.999% availability [ 1 ].
The technology seems to be based on InnoDB, SSD and some kind of replication with fail-over mechanism.

Unfortunately this product is neither open source nor is it really transparent what they are doing. Which is quite suspicious... Because this lack of transparency not everybody is happy with the product and the company.

Thanks to informations we have received and found in the web we know:

  • There were at least SchoonerSQL v3 [ 4 ] and SchoonerSQL v5 [ 5 ] on the market
  • SchoonerSQL v3 could be based on simple MMM technology [ 4 ]
  • SchoonerSQL v5 could be based on Galera Cluster [ 3 ]
  • SchoonerSQL v5.1 IS based on Galera Cluster [ 3 ]

Unfortunately we do not know much more about this product for the moment. If you have some more technical information we would be happy to hear about...
