To truly understand the difference between tablets and vNodes, we evaluated how ScyllaDB (tablets) and Cassandra (vNodes) compare under realistic conditions when they must increase capacity under active traffic. See what happened when we expanded both clusters step by step, captured how quickly capacity came online, how much the running workload was affected, and how each system performed after each expansion. https://ow.ly/gc0V50XWan6
Benchmarks show ScyllaDB tablet-based scaling 7.2× faster than Cassandra's vNode-based scaling (9× with cleanup), sustaining ~3.5X higher throughput with fewer errors
