Riak Enterprise is a commercially distributed product built on Riak (Apache 2.0-licensed) that extends Riak's capabilities with multi-datacenter replication, SNMP monitoring, JMX-Monitoring, and 24x7 support.
In multi-datacenter replication, one cluster acts as a “source cluster”. The source cluster replicates its data to one or more “sink clusters” in a full or real-time sync process. Data transfer is unidirectional (source -> sink). However, bidirectional synchronization can be achieved by configuring a pair of connections between clusters.
Multi-datacenter features can be used for:
- data locality
- disaster recovery
- global load balancing
- active backups
- secondary analytics clusters
- meeting regulatory requirements
