To other users of InfluxDB : How do you read data if you want to group, filter, sort by something other than time?

We used to use InfluxDB to store our perf data where every data point contained a timestamp (thus we thought influxdb was ideal for our use case). But, soon we wanted to group, filter, sort by various dimensions and it lead to performance issues.

Bringing it all in-mem and using pandas to do that was very slow for us. Also, creating indexes for so many columns didn't seem like a good idea.

We switched to postgres and the decision has served us well so far. I just want to understand if influx isn't suitable to our kind of use-case or we used it incorrectly.

InfluxDB 1.x was definitely not designed for that. With Flux in InfluxDB 2.0 you will be able to do things like store reference data in other places and join that with time series data in InfluxDB at query time. You can also sort, group and filter by any measurement, tag, field, or value. However, there are no user defined secondary indexes so the scope of this will be a bit more limited based on how things are stored. I'd have to know more about the specific kinds of queries to figure if it's something that would make sense within InfluxDB 2.
