How to set data retention time in DolphinDB?

Question

I would like to store device data in DolphinDB and keep data for 3 month. It is trouble to drop data manually by function dropPartition every 3 months. Can DolphinDB clear expired data automatically? Dose DolphinDB have retention policy like influxdb?

DolphinDB has a function "setRetentionPolicy" for this purpose.
