How we increased our EC2 event throughput by 50%, for free(TL;DR: using an SSD cache in front of EBS can give a massive I/O throughput boost) Background Internally, Swrve is built around an event-processing pipeline, processing data sent from 100 million devices around the world each month, in real time, with an average events-per-second throughput in the tens of thousands. Each event processor (or EP) stores its aggregated, per-user state as BDB-JE file
