How To Start with Apache Spark and Apache Cassandra

Apache Cassandra is a specific database that scales linearly. This has its price: specific table modelling, configurable consistency and limited analytics. Apple performs millions of operations per second on over 160,000 Cassandra instances while collecting over 100 PBs of data. You can bypass these limited analytics with the Apache Spark and the DataStax connector, and that’s what the story is about.

Setup

I’ve used one Apache Cassandra node on Docker

version: '3'

services:
  cassandra:
    image: cassandra:latest
    ports:
      - "9042:9042"

Apache Spark 3.0 is launched as shell with connector and Cassandra’s client library, which will be useful for timeuuid type conversion.

./spark-shell --packages com.datastax.spark:spark-cassandra-connector_2.12:3.0.0-beta,com.datastax.cassandra:cassandra-driver-core:3.9.0

If Cassandra is not running locally, you need to configure its address.

spark.conf.set("spark.cassandra.connection.host", "127.0.0.1")

Data

To test the Spark + Cassandra combination, I generated some date using mockaroo.com. It’s a list of sensors and a list of measurements from those sensors. You can find them in the repository on GitHub.
