The rest of the attributes are used by Spring Data to connect to the correct Cassandra cluster. Schema-action=NONE indicates that we do not want our database to be created or recreated on startup. In your application.propertiesfile, ensure you’ve included the following: -points=127.0.0.1 (or your corresponding connection uri) =default =9042 -action=NONE Connecting to Cassandra from a microserviceĬreate a new Spring Boot application using the spring initializer. If the connection was successful, we’re all set to start interacting with our database from an application. Once it’s installed, we can start cqlsh from any terminal using the command: cqlsh
#INSTALL CQLSH FOR CASSANDRA 2.1 MAC INSTALL#
It can be installed using pip: pip install cqlsh To interact with Cassandra through CQL, we’ll use a command line shell called cqlsh. Testing the connection to Cassandra through cqlshĬassandra uses the Cassandra Query Language ( CQL), which offers a model close to SQL. You should see the corresponding resources created: a stateful set, a service, and pods. Verify your installing by running: kubectl get all
Now that we have Kubernetes running locally, we’ll use a helm chart to deploy the database into our Kubernetes cluster.įirst, clone the Cassandra chart, then install it from the same directory you’ve cloned the repository into using the command: helm install -n cassandra incubator/cassandra Once we’ve setup minikube, we can start it using the command: minikube start Deploying Cassandra

We’ll setup a Cassandra cluster on minikube - A tool that runs a single-node Kubernetes cluster inside a Virtual Machine on your local machine.įor Mac users: install it with Homebrew brew cask install minikubeįor Linux users: install it with cURL curl -LO \ & sudo install minikube-linux-amd64 /usr/local/bin/minikubeįor Windows users: download and use the minikube installer.įor further support with installation, refer to minikube’s getting started guide. Setting up a Cassandra cluster Installing and starting minikube The objective is to eliminate implementation differences for Spring developers when using different data access technologies, relational and non-relational.īasically, it’s an umbrella project which contains many sub-projects that are specific to a given database, like Cassandra, MongoDB, Redis, and others. Spring DataĪccording to spring.io, Spring Data’s mission is to provide a familiar and consistent, Spring-based programming model for data access while still retaining the special traits of the underlying data store. From the perspective of a user, column-based and relational databases appear very similar. One that reads and writes columns of data rather than the rows. It carries the load for applications like Facebook, Netflix, and Reddit.Īs a Columnar NoSQL Database, it is optimized for quick lookups in large datasets. The Apache Cassandra NoSQL Database has always been a popular choice for heavy-load applications that require scalability, high availability and fault-tolerance without compromising performance.

In this guide, we’ll set up a Cassandra cluster on minikube, and learn how to use it from a Spring Boot microservice using Spring Data. Spring Data for Cassandra: A Complete Example
