I am using Influxdb v2.7.4 on a Raspberry pi 4 which boots from a 250GB SDD. In the buckets I collect sensor data, Temperature, Humidity etc, mostly floats. Data is supplied from Node-RED as messages, a topic and a value. Influxdb supplies the time stamp. I have not made any changes of default configuration.
I had less than a million values when my SDD was filled to 100% and I was quite surprised. After changing retention to 1 year the SDD went 17% filled and I can assure you that the deleted data was not enormous.
I note that with 1 year retention the Shard group duration is 168h and not 7h as specified in the InfluxDB documentation. Is that good or bad?
I have a Teslamate database running using a postgres database. Four years of vehicle details only takes 1GB of disk space.
What’s wrong with Influxdb? It looks like the first bucket I created, a TestBucket, contains a lot of Influxdb internal data which with a “forever” retention policy gets enormous. IS THIS TRUE???
The data belonging to my main bucket, HomeBucket, is quite small, as can be expected.
Does a lot of Influxdb “shit” fill up our hard drives? Shall I use a very low retention for my first bucket? Can I delete it?
Someone who knows must answer!!
