(TimescaleDB engineer) Actually, the reason we break out the Jsonb like this is because json blobs are big and take up a lot of space and so we normalize it out. This is the same thing that InfluxDB or Prometheus do under the hood. We also do this under the hood for Timescale-Prometheus. If you have a data model that is slightly more fixed than Prometheus, you'd create a column per tag and have a foreign-key to the labels table. That's a pretty simple schema which would avoid a whole lot of complexity in here. So if you are developing most apps this isn't a problem and filtering on dimensions/tags/labels isn't a problem. Again, this is only an issue of you have very dynamic user-defined tags, as Prometheus does. In which case you can just use Timescale-Prometheus.
