示例1: mergeMap

    mergeMap(({ payload: { serverId, kernelName } }) => {
      const configPath = [
        "entities",
        "serversById",
        serverId,
        "server",
        "config"
      ];
      const config = objectPath.get(state$.value, configPath);
      return kernels.start(config, kernelName, "").pipe(
        mergeMap(data => {
          const session = uuid();
          const kernel = Object.assign({}, data.response, {
            channel: kernels.connect(
              config,
              data.response.id,
              session
            )
          });

          kernel.channel.next(kernelInfoRequest());

          return merge(
            of(
              actions.activateKernelFulfilled({
                serverId,
                kernelName,
                kernel
              })
            )
          );
        })

      const serverConfig: ServerConfig = selectors.serverConfig(host);

      // TODO: This is the case where we didn't have a kernel before
      //       and they chose to switch kernels. Instead we need to allow
      //       "switching" by disregarding the previous kernel and creating a
      //       new session
      if (!oldKernelRef) {
        return empty();
      }

      const oldKernel = selectors.kernel(state, { kernelRef: oldKernelRef });
