Hi All,
I am interested in developing a Cayenne Adaptor for the NuoDB database
https://www.nuodb.com/
Its a very interesting database technology for developing scale out / high
availability solutions. The stuff that relational databases struggle with.
Presumably to get started I would need to create a NuoDBAdaptor extending *
org.apache.cayenne.dba.JdbcAdapter*. Is this the best place to start, does
anyone have any recommendations, or would like to be involved ?

Interesting. Their website is full of marketing speak, but very light on what makes this
database so "revolutionary". What is that attracts you to it over the choice of
existing open source databases?
If it supports the basic SQL specification, there is probably very little code
to implement in the Cayenne dba package.

Just to be clear Malcolm, I'm not being critical of your effort at all. The
more databases Cayenne supports the better. But I've never come across Nuo
before and I'm curious about what it offers. Certainly mysql's master/master
clustering capabilities leave a bit to be desired, but as a basic SQL/storage
engine I wonder how easy it would be for anyone to surpass postgresql/mysql
after all the years of bug fixing and tuning.
I've not been able to Google any benchmarks or other third party reviews. The
best I found was this:
http://sqlandsiva.blogspot.com.au/2011/11/nuodb-acid-compliant-scalable-cloud_02.html
which suggests that about 90% of the SQL standard is implemented. I guess the
real question is which 90%?
