Cassandra Practice Test

The recommended maximum partition size in Cassandra is generally considered to be 100MB. This guideline is based on the need to balance efficient read and write operations with the management of resources. Keeping partitions smaller than this threshold helps to avoid performance degradation that can arise from very large partitions. When partitions grow too large, it can lead to increased latency during read and write operations as the system has to handle more data in a single partition. Additionally, large partitions can complicate data management tasks such as compaction and repair, which may require more time and resources, thereby affecting the overall performance of the Cassandra cluster. Smaller partitions ensure that the system can efficiently distribute read and write loads across the nodes in the cluster, significantly enhancing performance, scalability, and availability. By adhering to this recommendation, users can generally maintain better control over the data in their tables, allowing for more predictable performance under varying workloads.
