You can run this on shared hostinghttp://ayende.com/157281/ravendb-changes-api-on-the-wire#comment15http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment15Mon, 30 Jul 2012 17:03:09 GMTSeeing that you have to configure special settings for IIS "turn off bufferring", does this mean anyone using shared hosting where you do not have administrative privileges on IIS will not be able to use this feature? http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment14http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment14Mon, 30 Jul 2012 11:10:53 GMTSeems silly.. Why not just use WebSync from Frozen Mountain? Way more developed than what you're talking about.http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment13http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment13Sun, 29 Jul 2012 06:44:04 GMTJohn, See my post about SignalR. I didn't feel like spending more time learning, testing and integrating another library (with the potential of discarding it in the end), where as I could spend a lot less time just building it myself.http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment12http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment12Fri, 27 Jul 2012 16:17:31 GMTAyende, Its interesting that you decided to roll your own solution. Usually its happening at the moment developer gets fed up with something and say - that's it I write my own! As for everyone streaming data/notifications though HTTP you do face exactly the same challenges, nothing unique. Question would be then, why not just use bosh with ejabberd, already proven/stable/scalable OS solution with multitude of extensions? Is it the same reason which brought you into writing your own solution? http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment11http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment11Fri, 27 Jul 2012 16:10:39 GMTShane, Oh, that shouldn't be an issue. It is really cheap to do this sort of things. You might need special config to handle this (remove default concurrent connection limits), but that would be about it. See how SingalR handles thishttp://ayende.com/157281/ravendb-changes-api-on-the-wire#comment10http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment10Fri, 27 Jul 2012 15:31:48 GMTHow many concurrent connections do you expect to handle or be able to handle. I'm sure server hardware has a large impact, but on an average webserver is this just background noise or will the perf be noticeable. I'm speaking more in general terms for this approach and not specifically how it works with RavenDB. I'm looking at 5k concurrent connections likely to a single server in my scenario and am wondering if this approach would be feasible.http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment9http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment9Fri, 27 Jul 2012 15:28:47 GMTJonnii, That is the idea, and it will be compatible with that when we release.http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment8http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment8Fri, 27 Jul 2012 14:23:16 GMTthis looks very similar to server side events in html5: http://dsheiko.com/weblog/html5-and-server-sent-events/http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment7http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment7Fri, 27 Jul 2012 12:26:35 GMTOlav, We have heartbeat going on in there.http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment6http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment6Fri, 27 Jul 2012 12:12:45 GMTInteresting stuff. How do you detect dropped connections if nothing is going across? I mean how will the client know if the server has just disappeared?http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment5http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment5Fri, 27 Jul 2012 12:08:13 GMTTobi, What mispelling? Oh, I see this now.http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment4http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment4Fri, 27 Jul 2012 11:23:04 GMTI hope the misspelling in "InitializeConnetion" doesn't go into production as you will be stuck with it like with "Referer" ;-)http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment3http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment3Fri, 27 Jul 2012 11:13:36 GMTSatish, Typically, you have one request per client, and it isn't hold a great deal of resources, so I am not worried about it at all.http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment2http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment2Fri, 27 Jul 2012 10:20:35 GMTHttpStreaming may need more resource incase if the server is holding the Request . So its better RavenDB should release a best practice document. it may be evil . Is it possible to switch to Web sockets if the implementation is available. http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment1http://ayende.com/157281/ravendb-changes-api-on-the-wire#comment1Fri, 27 Jul 2012 10:18:33 GMT
