> In our production cluster, we are seeing a large number of dropped mutations.
> At a minimum, we should print the time the thread took to get scheduled
> thereby dropping the mutation (We should also print the Message / Mutation so
> it helps in figuring out which column family was affected). This will help
> find the right tuning parameter for write_timeout_in_ms.
> The change is small and is in StorageProxy.java and MessagingTask.java. I
> will submit a patch shortly.
