DalmatinerDB is a metric database written in Erlang. It takes advantage of special properties of metrics to make trade-offs. The goal is to make a store for metric data (time, values) that is fast, has a low overhead, and is easy to query and manage.

What is DalmatinerDB?
DalmatinerDB is a no fluff purpose built metric database. Not a layer put on top of a general purpose database or datastore.
This allows features that otherwise wouldn't be possible: - a highly optimized network protocol - sequential reads/writes for metrics - and a client-server model that takes as much load from the actual store as possible
It leverages ZFS, Riak Core, a rich query language, and Grafana:
- ZFS is the world's most advanced filesystem. DalmatinerDB is built to take advantage of its features such as integrity, ARC, compression, and ZIL. - DalmatinerDB is built on Basho's riak_core, the same distribution framework used by the Riak database allowing for scalability and incredible resilience. - The frontend servers give users access to a rich SQL-like query language that's easy to use for both dev and ops. - DalmatinerDB integrates nicely with Grafana making it easy to build beautiful dashboards.
