Message chunking in Sandesha
Hi all,
I am new to Sandesha. I just downloaded the code few days ago.
I was searching for the part of code which responsible for chunking messages. As
far as I concern, WS-ReliableMessaging chunks messages into sequences and
deliver them one by one.
Perhaps, any of you can point me to which part of code/class in Sandesha
implementing chunking message.
thanks.

Hi Ramot,
Currently both Sandesha versions (Sandesha1 and Sandesha2) do not do such a
deviding of an application message into pieces. Such a functionality is not
specified in the WS-RM specification. The main aim of WS-RM is delivering
messages reliably from one end to another using acknoelwegement techniques.
So message devision is not a must. (But it could certainly improve the
performance since retransmissions will have to be done for only pieces not
for the complete message). I'm not sure weather other WS-RM implementations
do such a thing.
Thanks,
Chamikara

Quoting Chamikara Jayalath <ch...@gmail.com>:
I mean upper layer application message not SOAP message. I guess, SOAP message
is already at the lower layer.
I was thinking when application sends a large message to be delivered using
WS-RM, WS-RM might chunk the message into smaller messages (grouped by
sequenceID) and WS-RM sends them over SOAP one by one.
I haven't read WS-RM specification thoroughly, though.
thanks.

Hi Ramot,
If you are thinking that WS-RM chunk a single SOAP message into several
parts, thats wrong. What WS-RM does is grouping a set of messages. A message
group will be identified by an unique sequenceID and each message is given a
number as well ( 1,2,3,....). At the server side these sequenceIDs and
MessageNumbers can be used to invoke the messages in order.
So actually WS-RM does not chunk messages, it only numbers them.
Thanks,
Chamikara

Hi Ramot,
WS-ReliableMessaging protocol is not intended to chunk messages rather it
will arrange messages to a particular endpoint into a sequence.
So there are no class in Sandesha to chunk a given message into pieces.
Thanks,
Jaliya
