Setting Routing Hints

​

Overview

When using the Big Peer optional cloud deployment and managing large document collections, you can group peers with similar data access patterns by assigning specific labels, known as *routing hints. *

Represented as an unsigned integer with 32 bits (uint32), a routing hint is a value you define at the device level that the Big Peer references to optimize connections with peers consuming the same datasets.

​

Example Usage Scenario

In a scenario where several restaurants operate on the same Big Peer cloud instance and devices within each restaurant share the same cloud data, assigning a single routing hint across peers within each restaurant optimizes individual peer connections with the Big Peer.

Implementing Routing Hints

To set a routing hint in your app, from the top-most scope before starting the sync process:

1. Instantiate a TransportConfig object:

var config = DittoTransportConfig()

config.global.routingHint = 1234



ditto.transportConfig = config



do {

  try ditto.startSync()

} catch (let error) {

  print(error.localizedDescription)

}

2. Set the routingHint on the `
