I’ve been using the InfluxDB time series NoSQL database lately. I applied and was accecpted for a talk at InfluxDays, their 2019 user conference.

Here’s the recording:

I think it’s a decent match for research systems. You can get up to speed fairly quickly without a background in database systems, and the time-series first aspect of it is good for a wide range of datasets.


  • Easy to get started with many clients across most languages and a HTTP API.
  • Telegraf also records system metrics
  • Chronograf integration gives you visualization with low overhead.
  • NoSQL means you can change your schema as the experiment evolves (and you don’t even need a schema to get started).


  • Memory issues on IoT platforms (I’m using a snickerdoodle board).
    • Runs out of memory on start (supposedly fixed v1.7.8?)
    • Runs out of memory on compactions (fixed by moving to smaller shards)
    • Takes a long time to boot up and read lots of shards.
  • Python client doesn’t read into Pandas tables very well (it can write from them well). I usually export from chronograf into a .csv file and then pivot_table() a bunch.
  • Will drop points if the type doesn’t match (explicitly cast python variables).
