> If a component is set as {{runtimeLib=true}} it automatically becomes {{startup=lazy}} which means there is no way we can know that if the component could be successfully loaded till a request is made and the component is used. This is suboptimal behavior. The ops will have no means of knowing if everything is OK. Also , the first request will be unpredictably slow
> This means that , the server would keep checking for availability of blob store ( .system collection) and all components will get loaded as soon as the {{.system}} collection is available for querying
> Also, it will be possible for components to have an interface called {{BlobStoreAware}} . The component would get a callback as and when the blob store is available
