Can you delete data from influxdb?

With influx, you can only delete by time

For example, the following are invalid:

#Wrong
DELETE FROM foo WHERE time < '2014-06-30' and duration > 1000 #Can't delete if where clause has non time entity

This is how I was able to delete the data

DELETE FROM foo WHERE time > '2014-06-30' and time < '2014-06-30 15:16:01'

Update: this worked on influx 8. Supposedly it doesn't work on influx 9

I'm surprised that nobody has mentioned InfluxDB retention policies for automatic data removal. You can set a default retention policy and also set them on a per-database level.

From the docs:

CREATE RETENTION POLICY <retention_policy_name> ON <database_name> DURATION <duration> REPLICATION <n> [DEFAULT]

It appears that you can do this in influxdb 0.9. For instance, here's a query that just succeeded for me:

DROP SERIES FROM temperature WHERE machine='zagbar'
