when searching i came across one more NoSql DB called "OrientDB". Features looks interesting. it is scalable, supports both graph as well as document model but making a choice to use this DB is still under consideration. So i would like to know more about some real world example of using these databases in production. We are using Mysql for our application at phase 1 , but planning to migrate to nosql db and we want to make a wise decision no choosing a good nosql db. i need more statistics regrading the usage of these DB's. it would be helpful if i get some realtime statistics of performance and scalablity of these databases.
