> I want to check how this closure performs vs empty one:
> ignite.compute().affinityCall(xx, xx, new IgniteCallable<Object>() {
>     @IgniteInstanceResource
>     Ignite ignite;
>     
>     @SpringApplicationContextResource
>     ApplicationContext ctx;
>     
>     Object bean1;
>     Object bean2;
>     
>     
>     @Override public Object call() throws Exception {
>         bean1 = ctx.getBean(bean1class);
>         bean2 = ctx.getBean(bean2class);
>         
>         return null;
>     }
> });
> {noformat}
> Closure above is 3 times slower than Noop closure. Injections should be optimized.
> I see the following options:
> # Annotations
> ## Introduce SpringAware annotation and annotate each object that will need injection including SPI and internal stuff
> ## Support Spring Autowire annotation.
> ## I am not sure about the approach. We can use ApplicationContext.autowire() or generate and compile code that will do injections.
> # Interfaces
> ## IgniteAware
> ## Spring ApplicationContext aware
> ## ...
> Implementor should suggest and back solution with microbenchmarks.
