On non-intrusive workload-aware database replication

Narváez, Vaide ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2009 ; 2009INFO002.

Performance and high-availability are the crucial factors in the development of nowadays distributed database systems. Both of these challenges are commonly addressed by means of the same technique, database replication. The overall throughput of the system is increased by leveraging parallel computation on different sites, and in case of replica failures, availability is improved by...

High performance deferred update replication

Sciascia, Daniele ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2015 ; 2015INFO004.

Replication is a well-known approach to implementing storage systems that can tolerate failures. Replicated storage systems are designed such that the state of the system is kept at several replicas. A replication protocol ensures that the failure of a replica is masked by the rest of the system, in a way that is transparent to its users. Replicated storage systems are among the most...
