%description
    DalmatinerDB is a distributed Time-Series/Metric Database based on
    the Riak Core platform and Erlang. It provides: 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.
