Apache Cassandra 4.0 vs. ScyllaDB 4.4: Comparing Performance

The blog post compares the performance of Apache Cassandra 4.0 and ScyllaDB 4.4, highlighting significant improvements in ScyllaDB's throughput and administrative efficiency over Cassandra. ScyllaDB demonstrates superior performance with up to 5x greater traffic handling and lower latencies compared to Cassandra 4.0, especially during tasks like node addition, replacement, and major compactions. The benchmarks show that ScyllaDB can achieve similar performance to Cassandra using significantly fewer resources, offering potential cost savings and reduced administrative overhead. While Cassandra 4.0 shows marked improvements over version 3.11, particularly in latency and streaming processes, ScyllaDB provides additional features and efficiencies, such as a more manageable CDC implementation and lightweight transactions. The post suggests that while upgrading from Cassandra 3.11 to 4.0 is beneficial, further gains can be realized by considering ScyllaDB for its enhanced performance and feature set.
