Installing third-party data store operators

Each Instana data store is installed as a high-performing, distributed data store cluster, and is installed on the same cluster as the Instana backend. The installation uses third-party operators for installing the data stores. Each data store is managed by its respective operator.

You must install the following third-party data store operators. You can install these data stores in both online and air-gapped (offline) environments.

  • Apache Cassandra is a NoSQL distributed database. For more information, see Apache CassandraExternal link icon.

  • ClickHouse is a column-oriented database for generating powerful analytics, by using SQL queries, in real-time. For more information, see ClickHouseExternal link icon.

  • Elasticsearch is a distributed, RESTful search and analytics engine. For more information, see ElasticsearchExternal link icon.

  • Apache Kafka is an open source distributed event streaming platform. For more information, see Apache KafkaExternal link icon.

  • PostgreSQL is an open source object-relational database system. For more information, see PostgreSQLExternal link icon.

    You can install PostgreSQL by using the following operators:

    • CloudNativePG, which is a comprehensive platform that is designed to seamlessly manage PostgreSQL databases within Kubernetes environments. For more information, see CloudNativePG External link icon.
