I’m trying to test collecting high sample rate data (eg 100 Hz, or even 1000 or 500 Hz).
It seems typically data recording rates are closer to 1 Hz.
From a data collection/recording side, the first hurdle is the protocols to send data to influxdb. line protocol over HTTP is way to verbose…why send a timestamp for every single sample. UDP drops too many packets at this rate.
Has there ever been talk of a protocol that allows sending multiple samples at once, with a single timestamp (of the first sample) and a sample rate so all other timestamps are interpolated from the first? Even better, a compressed, binary format for these samples?
Our company has used packet-stores instead of a traditional or timeseries database for this reason – we store roughly 2sec of data (depending on compression) in each packet, and retrieve packets of data from the packet-store, rather than raw samples. We want to try out influx for this purpose instead, if it can handle the load.
This may be a non-starter if this is only the first issue we’ll encounter. My larger concern is that the influxdb data model is designed for many fields at ~1Hz maximum, and not fewer fields at high sample rates.
