Building Data Pipelines with Cassandra, Kafka, and Spark
Moving, storing, and analyzing data in microservice applications
Cassandra, Kafka, and Spark all represent ecosystems with many capabilities and integrations, so it can be confusing to understand when it’s best to use each—and for what purpose (e.g., Spark Streaming versus Kafka Streams or Kafka’s KSQL versus storing data in Cassandra). The best way forward is to learn how to use (and combine) each of these technologies effectively.
Join expert Jeff Carpenter to learn how to quickly assemble data pipelines using Cassandra, Kafka, and Spark. You’ll discover how to combine Kafka and Cassandra in microservice applications and use the Kafka Connect framework and the DataStax Kafka sink connectors. You’ll also explore the principles of Cassandra data modeling, learn how to design Cassandra tables and push data from Kafka topics into those tables, and dive into analyzing data in Cassandra using Spark.
What you'll learn-and how you can apply it
By the end of this live online course, you’ll understand:
- Design patterns for microservice-based applications using Kafka and Cassandra
- How to effectively combine Kafka, Cassandra, and Spark to move, store, and analyze data
And you’ll be able to:
- Build a microservice that stores data in Cassandra and publishes messages using Kafka
- Configure the Kafka Connect framework and the DataStax Kafka Connector to push data from Kafka topics into Cassandra
- Analyze data stored in Cassandra using DataFrames and SQL in Spark
This training course is for you because...
- You’re a developer creating microservice applications who wants to understand how to manage the flow of data between services and systems.
- You’re a data analyst, data engineer, data scientist, or machine learning engineer consuming data from microservice applications, and you want to understand how to obtain data you need.
- Basic programming experience with Java
- Familiarity with SQL (useful but not required)
