Data Replication

An Overview of Data Replication in Recital

There are two types of replication in Recital;

  • Master to Slave(s); where the updates are performed on one master server and published for slaves to subscribe.
  • Peer to Peer; where the updates are performed on many servers and the updates published for each server to subscribe.

Master-Slave Replication

This type of replication enables data from one Recital database server (called the master) to be published for replication for one or more Recital database servers (slaves) to subscribe. Replication is asynchronous - your replication slaves do not need to be connected permanently to receive updates published on the master. They just need to connect to the publisher when updating the subscription. Which means that updates can occur over long-distance connections and even temporary solutions such as a dial-up service. Depending on the configuration, you can replicate all databases, selected databases and even selected tables within a database.

Peer-Peer Replication

This type of replication enables data from one or more Recital database servers to be published for replication for one or more additional Recital database servers to subscribe. Replication is asynchronous - your replication subscription service does not need to be connected permanently to receive updates from the publication service. Which means that updates can occur over long-distance connections and even temporary solutions such as a dial-up service. Depending on the configuration, you can replicate all databases, selected databases and even selected tables within a database.
