Cassandra Columnar Store Service

WSO2 Column Store Service is based on the multi-tenanted Apache Cassandra. It offers highly-scalable, next-generation, distributed database management functionality, through the following feature in the WSO2 feature repository:

Name: WSO2 Carbon - Cassandra Feature
Identifier: org.wso2.carbon.cassandra.feature.group

Features can be installed or removed from the WSO2 Storage Server by following the instructions given in Installing Features.

Cassandra supports a Column Family based data model. The WSO2 Carbon Cassandra component uses the Carbon User Management component as the user base and helps users create and manage NoSQL data stores with authentication and authorization. The WSO2 Cassandra Explorer feature comes with a simplified management console UI. It allows users to add, view, manage and configure keyspaces, column families, columns and to explore and manipulate data.
