When using a Hybrid installation of Kong, how can the frequency of configuration updates between the Control Plane and Data Plane be controlled?

TL;DR
How can I control the frequency of configuration updates between the Control Plane and Data Plane in Kong Hybrid mode?
Set the db_update_frequency parameter, which controls how often Kong checks the datastore for updated entities. In Hybrid mode, the same parameter controls how frequently the Control Plane pushes configuration changes to the Data Plane, for example db_update_frequency=30 to sync every 30 seconds.
Solution
When using a Classic deployment of Kong where all nodes have access to the datastore, the frequency at which the database is checked for updated entities is controlled by the db_update_frequency parameter.
The same parameter is used in a Hybrid deployment to control how frequently the Control Plane will push configuration changes to the Data Plane. As an example, if you only wish to synchronize the configuration to the Data Plane every 30 seconds, then set the Kong configuration like this:
db_update_frequency=30This setting will make the Data Plane configuration push sleep for the configured db_update_frequency time.
