InfluxDB enforces what are known as "Retention Policies" to automatically manage the lifetime of data points in measurements.
The duration of the default retention policy in Aiven for InfluxDB data points is 720 hours, i.e. 30 days. Any data points older than this (compared to current time) will be automatically removed.
Retention policies can be managed using the InfluxDB query language commands
SHOW RETENTION POLICIES ,
CREATE RETENTION POLICY ,
ALTER RETENTION POLICY and
DROP RETENTION POLICY. You can find more about this commands in the InfluxDB documentation.
