Allow some percentage of data to be generated for an older timerange

In preparation for inserting into compressed hypertables, we would like to allow the generated data to accept a second range of time that randomly inserts records for that time range at a fixes percentage relative to the total rows.

This would typically be done after and initial load of data has been completed and tables have been compressed. We would then generate a second set of data, set create_metric_tables=false, and then insert the additional data.

Looking at the current parameters, maybe something like:

  • historical-timestamp-start: the start range for random, historical data
  • historical-timestamp-end: the end range for random, historical data
  • historical-percentage: the percentage of overall data (current + historical) that should come from the historical range.

This is just a place to start the discussion.
