It is a mature powerful search engine with extensive operator support. The IBM Cloud UI was super easy to use. Five operators for Apache Cassandra have been created that have made it easier to run containerized Cassandra on Kubernetes. K8ssandra consists of the aforementioned Cass-operator Kubernetes operator built and open sourced by DataStax, pre-built and pre-configured integrations with both Prometheus and Grafana, and two tools that came to Cassandra as part of the Last Pickle acquisition: Cassandra Reaper, an anti-entropy repair tool, and Cassandra Medusa, a data backup and restore tool. Referring to the helm commands from the prior FAQ: k8ssandra installs Kubernetes Operator for Apache Cassandra (cass-operator) and the Prometheus Operator. Note: The instructions below apply to OpenShift Dedicated as well. If you prefer Helm, you can use the OneAgent Helm chart as a basic alternative. I was recently given the opportunity to test out Cass-Operator on GKE and then had an internal ping to support the Cass Operator on IKS. The Jaeger Operator and Jaeger’s Helm chart (see Jaeger’s deployment tools on this post) ... Cassandra is a key-value database, so it is more efficient for retrieving traces by trace ID, but it does not provide the same powerful search capabilities as Elasticsearch. Continuing with the Kubernetes: monitoring with Prometheus – exporters, a Service Discovery, and its roles, where we configured Prometheus manually to see how it’s working – now, let’s try to use Prometheus Operator installed via Helm chart.. We need to modify the values.yaml file: provisionDataStore.cassandra=true - This the default value.

Apache Cassandra is a free and open-source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Here be dragons! Cassandra, a database, needs persistent storage to provide data durability (application state).In this example, a custom Cassandra seed provider lets the database discover new Cassandra instances as they join the Cassandra cluster. Operators are software extensions to Kubernetes that make use of custom resources to manage applications and their components. Operators follow Kubernetes principles, notably the control loop. k8ssandra-cluster installs an instance of the stack: reaper (repairs), medusa (backup/restores), the Grafana Operator, and instances. If an operator is like a robot in your datacenter running your Cassandra cluster, what does that operator need: a) To make informed decisions. Rounding out the distro are Helm charts for guiding database administrators and Site Reliability Engineers in setting up and operating Cassandra clusters within a Kubernetes environment. Discover and learn about everything Kubernetes % In this blog we'll compare a bunch of methods that can be used to manage installing Helm charts onto your Kubernetes… Example: Deploying Cassandra with a StatefulSet.

DataStax Kubernetes Operator for Apache Cassandra, cass-operator, is an open source operator deployed on VMware Tanzu Kubernetes Grid (TKG/I) via Helm. Helm based operator The Operator SDK. K8ssandra is deployed using helm and includes projects that the community has identified as essential for automating Cassandra: Cass-operator: an operator that serves as the translation layer between the control plane of Kubernetes and operations done by the Cassandra cluster. Recently the major contributors to these operators came together to discuss the creation of a community-based operator with the intent of making one that makes it easy to run C* on K8s.
