RDBMS: All content tagged as RDBMS in NoSQL databases and polyglot persistence
VMWare’s Cloud Foundry has the potential to become the preferred PaaS solution. It bundles together a set of services that it took years for other PaaS providers (Google App Engine, Microsoft Azure) to offer. And it seems that Cloud Foundry has much less (or none at all) vendor lock in.
From a storage perspective, Cloud Foundry is encouraging polyglot persistence right from the start offering access to a relational database (MySQL), a super-fast smart key-value store (Redis), and a popular document database (MongoDB). The only bit missing is a graph database.
I think the first graph database to get there will see an immediate bump in its adoption.

From Gavin Heavyside’s slides:
- Launch successful service
- Read saturation: add caching
- Write saturation: add hardware
- Queries slow down: denormalize
- Reads still too slow: prematerialise common queries, stop joining
- Writes too slow: drop secondary indexes and triggers
James Governor reporting from the HP CEO Leo Apotheker keynote at the HP Analyst Summit:
“traditional relational databases are becoming less and less relevant to the future stack”
Even if HP acquired the real-time analytics platform Vertica I haven’t heard of HP in the NoSQL space, so my first thought was this is just the usual attack on competitors.
But it could also express HP’s interest in getting into the NoSQL market. The games of speculations about HP’s acquisitions are open.
