Cassandra Operator (CassKop)
The CassKop Cassandra Kubernetes operator makes it easy to run Apache Cassandra on Kubernetes. Apache Cassandra is a popular, free, open-source, distributed wide column store, NoSQL database management system. The operator allows to easily create and manage racks and data centers aware Cassandra clusters.
CassKop creates/configures/manages Cassandra clusters atop Kubernetes and is by default space-scoped which means that :
This adds security between namespaces with a better isolation, and less work for each operator.
The following features are supported by CassKop:
Deployment of a C* cluster (rack or AZ aware)
Scaling up the cluster (with cleanup)
Scaling down the cluster (with decommission prior to Kubernetes scale down)
Pods operations (removenode, upgradesstable, cleanup, rebuild..)
Adding a Cassandra DC
Removing a Cassandra DC
Setting and modifying configuration files
Setting and modifying configuration parameters
Update of the Cassandra docker image
Rolling update of a Cassandra cluster
Update of Cassandra version (including upgradesstable in case of major upgrade)
Update of JVM
Update of configuration
Rolling restart of a Cassandra rack
Stopping a Kubernetes node for maintenance
Process a remove node (and create new Cassandra node on another Kubernetes node)
Process a replace address (of the old Cassandra node on another Kubernetes node)
Manage operations on pods through CassKop plugin (cleanup, rebuild, upgradesstable, removenode..)
Monitoring (using Instaclustr Prometheus exporter to Prometheus/Grafana)
Performing live backup of Cassandra datas (using Instaclustr sidecar)
Performing live restore of datas (using Instaclustr sidecar)
Performing live Cassandra repairs through the use of Cassandra reaper
