Does DolphinDB support retention policy?

Question

In InfluxDB I can create a two-hour retention policy like this:

> CREATE RETENTION POLICY "two_hours" ON "food_data" DURATION 2h REPLICATION 1 DEFAULT

In VictoriaMetrics, retention is configured with -retentionPeriod command-line flag. For instance, -retentionPeriod=3 means that the data will be stored for 3 months and then deleted.

Is there an equivalent function in DolphinDB?

Answer 1

Yes, dolphindb supports setting retention policies. You can call the function setRetentionPolicy to set .
