Through automation, Kubernetes operators simplify deployments and eliminate manual tasks to deliver scalable and repeatable processes. Some of these Kubernetes operators work with Apache Cassandra. Cassandra is a NoSQL, open-source database.
Choosing a Kubernetes Operator for MySQL
Choosing a Kubernetes Operator for MySQL Managing stateful applications like caches and databases running on Kubernetes is a tough task. With the Kubernetes API, you can build self-managing infrastructure by encoding operational knowledge and practices directly into code on demand. For example, when a MySQL container pod fails, you can use an operator to respond and take the appropriate action to bring the system back to life.
How to Combine Kafka and Cassandra on Kubernetes
Apache Kafka is a stream processing platform maintained by the Apache Foundation. Developers can use it with many different programming languages, like Node and Python.
