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 consistency levels for reads and writes.
