Abstract |
|
|
| Most operations in database (DB) is based on the deferred update replication technique, especially in distributed
environments. In deferred update replication, transactions are executed on a single host and broadcast to other hosts at commit
time. Upon delivering a transaction, each host confirms it to ensure a globally serializable execution. The mechanism is subject
to CAP theorem in order to ensure data consistency and availability. This paper proposes a dependable cache query mechanism in
distributed relational database (DRDB). The key insight of the cache query mechanism provides high performance, strong consistency
and availability for mass connection systems. In addition to presenting the cache query mechanism, we elaborate its implementation,
and provide an experiment and analysis of its performance. |
