ScyllaDB vs MongoDB vs PostgreSQL: Tractian’s Benchmarking & Migration

TRACTIAN embarked on a significant transition from MongoDB to ScyllaDB to accommodate a tenfold increase in data throughput and enhance their real-time machine learning environment. The decision was driven by ScyllaDB's scalability, high performance, and ability to handle large volumes of data, which were vital for TRACTIAN's needs. A comprehensive comparison of ScyllaDB with MongoDB and PostgreSQL highlighted ScyllaDB's superior performance, especially in terms of latency and throughput, although the migration process posed challenges including data modeling adjustments and infrastructure updates. The transition required meticulous planning and execution, with separate teams handling the old and new architectures to ensure continuous operation without outages. This process underscored the importance of selecting a database based on specific use cases, being prepared for mid-project changes, and focusing on the future potential of the product rather than the convenience of the current engineering setup.
