A Primary-Backup Protocol for In-Memory Database Replication

Rodrigo Malta Schmidt, Fernando Pedone

The paper presents a primary-backup protocol to manage replicated in-memory database systems (IMDBs). The protocol exploits two features of IMDBs: coarse-grain concurrency control and deferred disk writes. Primary crashes are quickly detected by backups an ...

Database Replication Using Generalized Snapshot Isolation

Willy Zwaenepoel, Sameh Mohamed Elnikety, Fernando Pedone

Generalized snapshot isolation extends snapshot isolation as used in Oracle and other databases in a manner suitable for replicated databases. While (conventional) snapshot isolation requires that transactions observe the “latest” snapshot of the database, ...

C-JDBC: Flexible Database Clustering Middleware

Willy Zwaenepoel, Emmanuel Cecchet

Large web or e-commerce sites are frequently hosted on clusters. Successful open-source tools exist for clustering the front tiers of such sites (web servers and application servers). No comparable success has been achieved for scaling the backend database ...

Pronto: High Availability for Standard Off-the-shelf Databases

Fernando Pedone

Enterprise applications typically store their state in databases. If a database fails, the application is unavailable while the database recovers. Database recovery is time consuming because it involves replaying the persistent transaction log. To isolate ...

The Database State Machine Approach

Rachid Guerraoui, André Schiper, Fernando Pedone

Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distributed transactional mechanisms, such as atomic commitment. We present the Database State Mac ...

Group communications and database replication

Matthias Wiesmann

Databases are an important part of today's IT infrastructure: both companies and state institutions rely on database systems to store most of their important data. As we are more and more dependent on database systems, securing this key facility is now a p ...

Replication et Durabilité dans les systèmes répartis

Distributed dats bases and data replication are recognised today as an efficient way to increase availability and fiability in data bases. The problem of mutual co-herence of copies is however introduced. Updating data is to be done on all copies. The noti ...

Database Replication Techniques: a three parameter classification

André Schiper, Matthias Wiesmann, Fernando Pedone

Data replication is an increasingly important topic as databases are more and more deployed over clusters of workstations. One of the challenges in database replication is to introduce replication without severely affecting performance. Because of this dif ...
