As someone who wants to pick up a time series DB to learn, what would be the best in terms of being the "industry standard"? InfluxDB? TimescaleDB?

I'm familiar with some basics of kdb and use it often in my day job, but from what I understand that isn't widely used outside of finance?

The following time series databases are popular right now:

* ClickHouse (this is a general-purpose OLAP database, but it is easy to adapt it to time series workloads)

* InfluxDB

* TimescaleDB

* M3DB

* Cortex

* VictoriaMetrics

The last three of these TSDBs support PromQL query language - the most practical query language for typical time series queries [1]. So I'd recommend starting from learning PromQL and then evaluating time series databases from the list above.

(I work at TimescaleDB.)

If you are familiar with Postgres and/or SQL, then you may want to start with TimescaleDB. It's just Postgres for time-series. Full SQL, so it's possible to be productive instantly.
