Real-Time Write Heavy Database Workloads: Considerations & Tips

Real-time, write-heavy database workloads present a unique set of performance challenges that differ significantly from read-heavy systems. These workloads are characterized by extremely high ingestion rates (often exceeding 50,000 operations per second), a greater volume of writes than reads, and strict latency requirements—frequently demanding single-digit millisecond P99 performance. Such conditions are common in modern systems like IoT platforms, online gaming engines, logging and monitoring pipelines, e-commerce platforms, ad tech bidding systems, and real-time financial exchanges.
