Bounded Delay Replication in Distributed Databases with Eventual Consistency
Högskolan i Skövde, Institutionen för datavetenskap.
2003 (engelsk)Independent thesis Advanced level (degree of Master (One Year))Oppgave
Abstract [en]

Distributed real-time database systems demand consistency and timeliness. One approach for this problem is eventual consistency which guarantees local consistency within predictable time. Global consistency can be reached by best effort mechanisms but for some scenarios, e.g. an alarm signal, this may not be suffcient. Bounded delay replication, which provides global consistency in bounded time, ensures that after the local commit of a transaction updates are propagated to and integrated at any remote node within bounded time. The DRTS group at the University of Skövde is working on a project called DeeDS, which is a distributed real-time database prototype. In this prototype, eventual consistency with as

soon as possible (ASAP) replication is implemented. The goal of this dissertation is to further develop replication in this prototype in coexistence to the existing eventual consistency which implies the extension of both the theory and the implementation.

The main issue with bounded time replication is to make all parts, which are involved in the replication process predictable and simultaneously support eventual consistency with as soon as possible replication.
