I am a newbie to Influxdb & time series db.
here is my use case to test and evaluate.
storing device metrics… have 1Million device ( device id 1,2…1M for simplicity) … Assume each device will be capturing around 50 different values ( lets just say I can keep them all as fields)
Going by the docs, if I tag device_id , then it would follow the path of High Cardinality series ( assume device id would be one of the many tags…total tags<=6)
if I split each device into its own measurement, then its considered sub-optimal schema ( ref: https://community.influxdata.com/t/schema-shard-configuration-for-storing-dense-long-term-historical-data/511/4?u=venk )
if I dont tag device_id, then I lose the capability of querying data by device…
I am confused on how this gets handled. looks very straight-fwd situation.
any insights pls?
Regards
