messaging

问题 I want to make a small(est) app which uses only ignite-core-2.0.0 and does Ignite messaging. There is a cluster somewhere which I want to exchange messages with. I've set IGNITE_HOME to ./apache-ignite-2.0.0-src where I've got compiled sources. File IGNITE_HOME/config/default-config.xml exists and isn't changed. Here is the code running before the exception Ignition.setClientMode(true); Ignite ignite = Ignition.start(); ... I'm getting Exception in thread "main" class org.apache.ignite

问题 I have a collection for conversations: {_id: ..., from: userA, to: userB, message: "Hello!", datetime: ...} I want to show a preview of user's conversations - last message from each conversation between current user and any other users. So when user clicks on some "last message" he goes to next page with all messages between him and that user. How do I do that (get 1 last message from each conversation) without Map/Reduce? 1) use "distinct" command? (how?) 2) set "last" flag for last message?

问题 I am attempting to convert my v1 function to a v2 function, but I cannot find a replacement for deferring a message. In V1 of Azure Functions it was a method on the BrokeredMesage called .DeferAsync() . In V2 there is no longer a BrokeredMessage but just a Microsoft.Azure.ServiceBus.Message and this does not contain the method of .DeferAsync() . According to the docs: The API is BrokeredMessage.Defer or BrokeredMessage.DeferAsync in the .NET Framework client, MessageReceiver.DeferAsync in the

问题 Can PHP treat AMQP like an RPC service, and send a message and block until a reply is returned? Are there any good examples of this, and do any libraries wrap such functionality up in an easy-to-use way? I'd like to have the flexibility of a brokered messaging system, but shield the web tier from needing to know about its asynchronous nature. 回答1: Sure, absolutely. Look at how an RPC-style request flows around a system: A request is issued The requester now blocks waiting for a reply to that

问题 I followed the demo given at http://developer.android.com/google/gcm/gs.html and got a trial application, GCMTrial to work correctly. But, i tried to follow the same steps on an existing application but it didnot work. So I made an entirely new project. But even then , following the same exact steps, I couldnt get GCM to send a message successfully. So I tried renaming GCMTrial to the required name, and not that too does not work. I register for GCM via the main activity and get the following

问题 How can we transform cleanly a communication based on HTTP API --> to a message communication using ZMQ library ? 回答1: In case you indeed want to do so, one may design a kind of Mediator, using ZeroMQ tools. ZeroMQ has a set of multi-level abstractions, where AccessPoints, typically have a certain "behaviour" ( a distributed behaviour ) they perform among themselves. Your indicated target aims at using no such behaviour, but to have some sort of transparent, (almost) wire-level handling of

问题 what are my options for reliable multicast in c# /.Net 3.5? I don’t want to use MSMQ. I am open to commercial as well as open source options. Thanks 回答1: Take a look at EmCaster 回答2: http://www.29west.com/ claims to be the lowest latency reliable multicast solution available. I have not verified this claim, but in talking to them, it seems that their biggest competition is not some other vendor, but in house developemnt. Why not just set up your own multicast group, and use it directly?

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 6 years ago . I am trying to figure out exactly how I can capture all window messages of a process/window, from the time it was launched in c#. The process would not be my own so I would need to use some kind of hook. My goal is to start capturing all messages in real time from before the
