Time Series tech stacks for the IoT Edge
No matter what type of IoT devices you have, or what your use
case is for them, you’re going to end up producing a lot of time
series data. What you use to handle it is going to be as important
to your success as the code you write yourself.
This talk will evaluate the available open source tools for the
collection, activation, transmission and visualization of time
series data on the IoT Edge, and demonstrate how to use them,
together with InfluxDB, to solve various use cases for the Internet
of Things.
