Raspberry Pi InfluxDB: The solution for IoT Data storage

Raspberry Pi is costeffect linux computer very commonly used for IoT home automation projects.

Here are the 3 problems with conventional databases for IoT data store applications:

  • Too much or complex configuration
  • Unable to expire data / set retentional policies
  • Not tailor made of Time Series Data
