CAP theorem
continuous synchronizatio - Opis:
- Database replication is a way to improve system throughput or achieve highavailability. In most cases, the use of an active-active replica architecture isefficient and easy to deploy. Such a system has CP properties (from the CAPtheorem: consistency, availability, and network-partition tolerance). Creat-ing an AP (available and partition-tolerant) system requires the use of multi-primary replication. Because of the many difficulties in its implementation, thisapproach is not widely used; however, ALICE’s deployment of CCDB (exper-iment conditions and calibration database) needs to be an AP system in twolocations. This necessity became the inspiration for examining the state-of-the-art methods in this field and testing the available solutions. The tests thatwere performed evaluated the performance of the chosen replication tools: Bu-cardo, and EDB Replication Server; these showed that the tested tools couldbe successfully used for the continuous synchronization of two independentdatabase instances.
