Creates a new instance of the Pregel graph with updated configuration. This method follows the immutable pattern - instead of modifying the current instance, it returns a new instance with the merged configuration.
The configuration to merge with the current configuration
// Create a new instance with debug enabled
const debugGraph = graph.withConfig({ debug: true });
// Create a new instance with a specific thread ID
const threadGraph = graph.withConfig({
configurable: { thread_id: "123" }
});
