> If processing of update on NN takes more than the cache interval time(default:30 secs), it is possible that two updates will be processed parallely leading to unexpected behavior. We should instead lock the processing of updates so that we ensure they happen sequentially. Also while doing so, we should add a flag like "processingUpdate", which if true, we should never go into stale mode even after threshold time.
