I like it. The common workaround I've used in these scenarios is to batch
work, but then you'd run into the case where a single batch got too big and
the distributed transaction would simply fail... I like the potential that
my handler could say, "I'm 99% of the way through after running for 60
seconds, just give me a little longer" and have the message lock extended.
I like the idea of having the interface where my handler could be as smart
or simple as I like:
- return true; // Just keep extending forever
- return stillMakingProgress(); // Can inspect some state on the handler
- if (stillMakingProgress()) { return true; } else { cancel(); return
false; } // Make the determination we aren't progressing, so break the
loop, log the cancellation, and don't request an extension
RE: Periodicity, perhaps 50% of the message lock expiration timeout? In the
default case, timeout = 30seconds, poll the handler every 15seconds.

When we pop a message from a queue we're given a lock on that message for
a short period of time. The idea is that if our handler hangs or crashes
without calling .Complete or .Abandon then the message will be returned to
the queue so that someone else can handle it.There's a trade-off between 1) detecting handlers that have crashed and
giving someone else a chance at handling the message and 2) allowing
long-running handlers to do their job.I'm thinking about either of:
- an optional interface on IHandleXXX<..> along the lines of
IAmALongRunningTask that would allow the dispatcher to ask the handler
whether it was still alive.- simply attaching a watcher to any handler task to check if it's
still alive.Any thoughts? @DamianMac https://github.com/DamianMac? @michaelnoonanhttps://github.com/michaelnoonan
