------------------------------------
[~clockfly] Could you post a PR based on patch if you don't mind?
Github diff UI makes me comfortable to review, especially I can see changeset
with unchanged part of source codes. (Since I'm newbie of Storm, so it could
help me.)
Or could you recommend GUI tool which visualizes patch file? (supports unified
and split)

> blocking. My biggest concern around the blocking is in the case of a worker
> crashing. If a single worker crashes this can block the entire topology from
> executing until that worker comes back up. In some cases I can see that being
> something that you would want. In other cases I can see speed being the
> primary concern and some users would like to get partial data fast, rather
> then accurate data later.
> Could we make it configurable on a follow up JIRA where we can have a max
> limit to the buffering that is allowed, before we block, or throw data away
> (which is what zeromq does)?

> If some worker crash suddenly, how to handle the message which was supposed

> 1. Should we buffer all message infinitely?
> 2. Should we block the message sending until the connection is resumed?
> 3. Should we config a buffer limit, try to buffer the message first, if the
> limit is met, then block?
> 4. Should we neither block, nor buffer too much, but choose to drop the
> messages, and use the built-in storm failover mechanism?
