Terracotta Cluster Events and nodeLeft

[Artyom Sokolov]

Hi.

According to the updated documentation nodeLeft event may not occur if
the application was killed with "kill -9". If I understand correct it
is concerned about *killed* node only, and another nodes *will*
receive nodeLeft event if one is gone because of "kill -9".

(Small example: consider one server SERVER-A and multiple nodes
NODE-A, NODE-B, NODE-C, NODE-D. Client reconnect window is *finite*.
Node C was killed with "kill -9" (or the computer just blew up).
NODE-C did not receive nodeLeft, but NODE-A, NODE-B and NODE-D
received)

Do I understand the subject right? Please correct me if I'm wrong.
It's not clear for me.

Thanks.

Hello Everyone,

I was testing terracotta using large datasets and was looking into the Master Worker Pattern. I found out some of the examples here

http://www.terracotta.org/confluence/display/labs/Master+Worker

But i couldn't find any good documents/ tutorial for using the TIM  master Worker module other than the small code snippets given here
http://forge.terracotta.org/releases/projects/tim-messaging/docs/quickstart.html

Can anyone point me to the right documents/tutorial?

Thanks

Regards,
ren

Those docs/samples are outdated and do not refer to the current
tim-masterworker implementation.

That's currently the most up-to-date documentation.
However, there are a lot of code samples showing API usage among
tim-masterworker tests and system tests: just take a look at the
source code.
And obviously, do not hesitate to ask if you need any info.

Cheers,

Sergio B.

By next weekend we'll roll out another update to the cluster-events doc that will further clarify the way it works.
