routing
The routing hint for this device.
A routing hint is a performance tuning option which can improve the performance of applications that use large collections. Ditto will make a best effort to co-locate data for the same routing key. In most circumstances, this should substantially improve responsiveness of the Ditto Cloud.
The value of the routing hint is application specific - you are free to chose any value. Devices which you expect to operate on much the same data should be configured to use the same value.
A routing hint does not partition data. The value of the routing hint will not affect the data returned for a query. The routing hint only improves the efficiency of the Cloud's ability to satisfy the query.
