High Availability with Apache ZooKeeper

High Availability with Apache ZooKeeper

MDM Registry Edition
 uses Apache ZooKeeper to achieve high availability for Rulebase Servers, updsync utility, and updmulti utility in a distributed environment. High availability refers to the availability of the resources without any service interruption if a failure occurs.
When you start a Rulebase Server, it starts as a secondary server, and one of the secondary servers become the primary server. The primary server responds to all the queries. If the primary server is down, any secondary server is elected as the primary server, and the new primary server responds to the queries.
If you specify the local host as a ZooKeeper server during the installation, the installer installs ZooKeeper.
