I kind of agree with the assessment.

I've been prototyping with VoltDB be/c it has a pretty interesting model that should be able to achieve a near-linear scale of write operations for tables that are partitioned. After reading the docs on VoltDB [1] is became clear to me that they are putting the design constraints up front and if you can work through those constraints [2] you can achieve some wicked scale. But it's a bit more complex than your typical single host database.

The work that VoltDB makes you deal with up front are a lot like the work that would have to be done for a multi-master setup in PostgreSQL to function correctly. I like how VoltDB puts those problems up front, but I'm having problems seeing VoltDB as a general purpose solution. The old PG database I work on right now I can't see in the VoltDB, but maybe parts of it would fit OK.

I look forward to the tooling in PG to get better and better. It's a great community and I do like the work that 2ndquandrant is doing. I like how they approach the community with their work. I do the BDR work is important to understand so that when you're in a situation that calls for it you can take advantage of it (same with VoltDB).

If you have any question about whether VoltDB could fit or not, let us know. It's surely not as general purpose as PG, but yes, it's faster for many use cases and its clustering is fully consistent.

Thanks! I certainly will. It looks pretty cool. I'm certainly learning it and finding the technical details in the documentation to be quite interesting.
