Fast Data is about processing high velocity data in real-time as it happens. Think of Fast Data as Big Data in real-time.
So what does APM have to do with Fast Data?
APM is all about processing lots and lots of data as close as possible to real-time.
Tracking transactions, analyzing logs, sampling metrics, figuring out relationships, dependencies, business impact and probable root-cause. APM is about crunching data and gaining valuable insight fast. APM must also combine Fast Data with Big Data Analytics — processing data in motion and crunching data @ rest. In APM data @ rest is history: end-user behavior, performance, KPIs, transactions, logs. It tells you what happened; long term trends.
Fast Data is all about high velocity, all about NOW.
