Are you considering configurable automated downsampling triggers for inserts over time buckets? Essentially these would be aggregates triggered to fire and insert the resulting values into another table of lower granularity after the time bucket has closed (1s, 10s, 1m, 5m, etc.)

This is a great usage idea and something that should be fairly easy once we support close and update triggers (on our list of todos)

And just to follow-on previous comment: Yes, we plan to offer such continuous aggregations, where data of lower granularity can then just be automatically written into a different hypertable.

This also plays nicely with configurable data retention policies if desired, e.g., only store raw data for X days, but more aggregated data for longer periods of time.
