Transactions, Messages and Events: Merging Group Communication and Database Systems
Bettina Kemme, Gustavo Alonso
Abstract:
In this paper, we report on the DRAGON (Database Replication on Group
Communication) project and the results obtained so far at ETH
Zürich. The goal of DRAGON is to improve database replication
strategies by using group communication primitives. As a first step in
this direction, we have developed a suite of protocols implementing
database replication based on broadcast primitives. We are currently
embedding these protocols into a database management system to show
the feasibility of the approach. In this short paper, we briefly
discuss these protocols and analyze how they can be included in a
database system. Our contribution is to further clarify the effort
involved in the process and to explicitly state some of the issues
commonly not considered by existing work. These issues are analyzed
in detail and solutions are provided taking as example our current
development efforts.
