io.deephaven.enterprise.dnd.ControllerClientFactory

@Module
public class ControllerClientFactory
extends Object

A lazy provider of the singleton controller client for queries. Some operations require the controller client, and we do not want to create one unless it is necessary, or create more than one to avoid additional controller load. The client is currently used for:

• PQ URI resolution.
• Variable updates.
• Heartbeat requests
