Re: messaging behavior

Hi! I think in your case you need to improve your protocol: send to back ack message. Ack message will be sent to sender node when original message processed. On Fri, Jun 16, 2017 at 10:15 AM, shawn.du wrote: > Hi, > > I want to use ignite messaging to send notifications to some client nodes. >

Re: Understanding peerclassloading

After some more testing it seems to be related to ear and classloading. a war deployment seems to be OK, but in an ear I need the "toArray" workaround. I can also check with the tomee guys. /hw to., 15.06.2017 kl. 15.38 +0200, skrev Helge Waastad: > Hi, > running 2.0 > > https://github.com/hwa

is it possible to use file based cachestore for persistence?

Hi, I would like to use a file based persistence instead of cassandra as it becomes a bottleneck even if i try all the async/batching options. Could you please enlighten us if there is such option like using directly the filesystem like hdfs or any other thing? Regards -- View this message in

Re: Understanding peerclassloading

Ok, getting somewhere here. Reason for this issue is that the library is bundled in the WEB-INF/lib of the war and not ear/lib. If I make the war 100% skinny, classloading works fine. (But it's not an option putting jsf libs in ear/lib due to a lot of other issues) /hw   fr., 16.06.2017 kl. 10.27

No, Ignite doesn't have it for now. Likely, Ignite 2.1 will have a persistence layer. See [1] for details. [1] http://apache-ignite-developers.2346864.n4.nabble.com/GridGain-Donates-Persistent-Distributed-Store-To-ASF-Apache-Ignite-td16788.html On Fri, Jun 16, 2017 at 12:11 PM, fatality wrote:
