ThreadRuntimeFactory

public ThreadRuntimeFactory(String threadGroupName,
                            String pulsarServiceUrl,
                            String storageServiceUrl,

                     throws Exception

This constructor is used by other runtimes (e.g. ProcessRuntime and KubernetesRuntime) that rely on ThreadRuntime to actually run an instance of the function. When used by other runtimes, the arguments such as secretsProvider and rootClassLoader will be provided.

Throws:

Exception
