How to Configure Database Retension Policies in InfludDB 3

The “create a database” documentation mentions that retention policies are integral to a dtabase in InfluxDB 3, but I can’t find any documentation of how to specify the duration of a retention policy for a newly created database, or how to modify the policy for an existing database.

I’ve searched:

  • The influxdb3 cli tool, influxdb3 create database --help-all
  • create a database
  • Generic documentation for both Core and Enterprise flavors.

Can anyone show how to set this up? I have a large volume of data which I would like to carefully bound.
