Modify a collection

This topic describes how to modify the properties, especially the time to live (TTL), of a collection.

Currently, the TTL feature is only available in Python.

collection.set_properties(properties={"collection.ttl.seconds": 1800})

The example above changes the collection TTL to 1800 seconds.

Parameter	Description	Option
Properties: collection.ttl.seconds	Collection time to live (TTL) is the expiration time of data in a collection. Expired data in the collection will be cleaned up and will not be involved in searches or queries. Specify TTL in the unit of seconds.	The value should be 0 or greater. The default value is 0, which means TTL is disabled.
