title: Which database to store big metric data on Raspberry Pi?
body: <p>I want to use Raspberry Pi as an independent sensor, which will measure some value each second and store this metric data into a local database. Then I would like to query the database based on the date range. Which database should I use, taking into account the limited resources of RPi and that there will be ca. 30758400 records/year? Are there any RPi-specific lightweight database engines especially for this purpose?</p>
