It is implemented within the cluster to utilize multiple replicas of data and provides an eventually consistent data store, by default. Through modification of the configuration, immediate consistency can also be achieved, though at a performance cost./7.1/ha/ha_configuration/Mon, 01 Jan 0001 00:00:00 +0000/7.1/ha/ha_configuration/Pre-requisites Configuration Enable HA Config HA APIs Connectors External Data Management Pre-requisites An HA installation requires the following components: Two or more clusters with matching Kinetica installations managed by KAgent Note If the clusters are not managed, KAgent should be installed and then the clusters should be added to it. Two nodes (across the clusters) have RabbitMQ installed etcd The KAgent UI Configuration Enable HA HA is enabled on a ring using the KAgent UI.
