DS201 Exercise 12: Consistency
- Difficulty: Beginner
- Time: 10 minutes
In this hands-on lab, you will:
- Determine the current consistency level used by cqlsh
- Change the consistency level for reads and writes executed by cqlsh
- Observe how the availability of data changes with different consistency levels
One of the challenges of distributed systems, like Apache Cassandra™, is how to balance keeping your data consistent across multiple replicas while maintaining high availability. Fortunately, Cassandra lets you tune this balancing to your needs by setting a consistency level for reads and writes.
