Cassandra Analytics provides the Cassandra Spark Bulk Reader, an open-source library that lets you run arbitrary Spark jobs against an Apache Cassandra cluster. It connects securely to your cluster and loads data into Spark, so data engineers and homelab users can query Cassandra with Spark SQL and build data pipelines without writing custom connectors.

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

First-install notes

  • Create a database login before you rely on it Once Cassandra is running, create a named CQL user and keep its password in a safe place. This gives you a clear account to use and helps avoid depending on default access or forgetting how to connect. source

Common questions

How do I configure a Spark job to read from Cassandra with the Bulk Reader?

Use the CassandraDataSource and set options such as sidecar contact points, keyspace, table, DC, createSnapshot, and numCores. The example also covers setting up Cassandra 4.0 and Apache Sidecar.

What database account should I create before relying on a running Cassandra cluster?

Create a named CQL user and keep its password in a safe place. This gives you a clear account to use and helps avoid depending on default access or forgetting how to connect.

Why can't listen_address be set to 0.0.0.0 so the node listens on all addresses?

Cassandra is a gossip-based distributed system. listen_address is the address a node tells other nodes to reach it at.

Where are issues for the Cassandra Analytics library tracked?

Issues are tracked in JIRA. Contributions can be discussed on #cassandra-dev in ASF Slack.
