Cassandra vs failures, latency edition

Masterless databases like Cassandra are designed to handle any failure without interruption, including node failures, garbage collection pauses, or slow disks. These failures are indistinguishable from network partitions in the system. This fault-tolerant design also helps lower latency as there is no artificial bottleneck that causes spikes during hiccups. Cassandra's faster overall performance and fault-tolerant design allow it to achieve low latency, such as serving 99th percentile of reads under 10 ms in many clusters.
