Requirements and Design of Replication Services for a Time Series Management System

This paper analyzes how financial researchers manage large numbers of time series and how they work with these data. We show that replication services are a central facility of a time series management system and we define the requirements for such replication services. An evaluation of current time series management systems shows that they do not support replication. Neither replication systems of other database management systems nor other kinds of currently available replication systems cover our requirements. Thus, we present our design of replication services that are adapted to the needs of time series management. It is based on a publish-andsubscribe mechanism, a sophisticated scheduling facility, dynamic replication, and integrated directory ser-
