Replication mechanisms for a distributed time series storage and retrieval service

In this paper we present the prototype architecture of a distributed service which stores and retrieves time series data, together with replication mechanisms employed in order to provide both reliability and load balancing. The entries of each time series are stored locally on the machines running the instances of the service. Each entry is eventually fully replicated on every service instance. Our replication mechanisms depend on whether there is only one service instance receiving each entry of a time series from a client or there may be multiple such instances.
