Hi ,
I have query related to Publish/Subscribe vs Publish/Subscibe Routing(Bridge Design Pattern).Which is the best scalable messaging pattern that suits the below usecase in Message Broker environment?
Our scenario has a publisher and multiple subscribers.Publisher publishes the messages in the form CDM(Cannonical Data Format) to a Source topic and all the subscribers need to consume those messages.Which is the best Messaging pattern to fulfill this requirement.
Assuptions:
1.Message is of 1 lakh records
2.Mode is non Persistant
3.Frequency of Messages is like 10 msg/Hour
Regards,

I would most certainly not be worrying about performance for something that is happening at a rate of 10 messages and hour.
Just get on with whatever works for you.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Thanks for the reply.
Lets say tomorrow if we get 10000 msg's per hour and each msg has around 10 million records.Which message pattern is the most optimal. |

Your assumptions are all wrong. You don't have 1 message with 1 lakh records, you have 1 lakh messages.
They may be related or not. The essential information is that they should be able to process independantly... have fun

So what are the qualitative differences between the two patterns you're asking about?
One is straight pub/sub.
The other is pub/sub with *additional business function*.
How is this a performance question?
You either need the additional business function, or you don't.
If you need it, then you can't use plain pub/sub.
If you don't need it, then why would you use it? |

Hi ,
Yes.I am trying to figure out which is the best qualitative patterns among Plain Pub/Sub and Bridge Pattern.
As per my understanding is that
1. if I want add additional bussiness functions to specific consumer(among many) then plain pub/Sub will not work.
2.Also in Plain Pub/Sub if i want to purge the messages all the consumers who are subscribing to the topi will get affected.
3.Plain Pub/Sub does'nt support scalability as the subscribers are directly listening to the topic.But the bridge design pattern all the messages are transported from source topic to Subscriber queues.Since subscriber is listening to the queue we can load balance multiple subsciber instances.
Please let me know my understanding is correct.. |

No, not really.
At least not for MQ. |
