`/admin/collections?action=MODIFYCOLLECTION&collection=_<collection-name>&<attribute-name>=<attribute-value>&<another-attribute-name>=<another-value>_&<yet_another_attribute_name>=`
It's possible to edit multiple attributes at a time. Changing these values only updates the z-node on ZooKeeper, they do not change the topology of the collection. For instance, increasing `replicationFactor` will _not_ automatically add more replicas to the collection but _will_ allow more ADDREPLICA commands to succeed.
An attribute can be deleted by passing an empty value e.g. `yet_another_attribute_name=` will delete the `yet_another_attribute_name` parameter from the collection.
