ScyllaDB on Oracle Cloud Infrastructure: A Look at Stable Performance in the Event of a Node Failure

ScyllaDB is now available on Oracle Cloud Marketplace, offering stable performance even in the event of a node failure, thanks to its Heat weighted load balancing feature introduced in ScyllaDB 2.0. Testing on Oracle Cloud Infrastructure's bare metal instances demonstrated ScyllaDB's ability to maintain throughput and latency performance, leveraging OCI's high CPU count, ample DRAM, and fast NVMe drives. During node drops, which are common in distributed systems, ScyllaDB can sustain approximately 2 million read operations per second by redistributing the load across remaining nodes without requiring additional tuning. Under normal conditions, with all nodes operational, the system can handle at least 4 million operations per second, storing data with a replication factor of three and maintaining quorum consistency levels.
