https://docs.influxdata.com/influxdb/v1.0/concepts/glossary/... You want to keep the amount of different data that you are indexing/tagging on low. As an example with my situation, I was tracking what could be amounted to connections between nodes in a very large tree. I had a lot of distinct pairs, which means that I had a high cardinality. When the cardinality increases a query that used to take a millisecond to load could move to a couple seconds. |

At what level of keys or tags did you start to see query performance become problematic?
