> Currently, these commands alter the state of CacheAtomicLong, but they will be more flexible if they atomically change cache key-value mapping.
> Consider the following:
> # Move handling logic to GridCacheCommandHandler
> # Whenever command is received handling node should call {{org.apache.ignite.IgniteCache#invoke(K, org.apache.ignite.cache.CacheEntryProcessor<K,V,T>, java.lang.Object...)}} to properly change the value (depending on the argument) and return result
> # If value is not a Number, error should be returned to the caller.
