> [~revans2] wrote: Your logic makes since to me on why these calls are
> 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)?
> {quote}
> If some worker crash suddenly, how to handle the message which was supposed
> to be delivered to the worker?
> 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?
