IgniteUtils NoClassDefFoundError

Hi All, I'm getting an error on application startup which has me stumped. I've imported ignite-core, indexing, slf4j and spring-data via maven, version 2.6.0. I'm using ignite to do some cache operations, basic stuff cross-node. However when I start it, it runs until the config of static ip

RE: Ignite Thin Client Continuous Query

Gordon, Yes, generally we do recommend using thin client for such applications. However, it doesn't mean that you can't us client node in case it's really needed, although it might require some additional tuning. Would you mind telling if you have any other technology in mind? I highly doubt

RE: Ignite Thin Client Continuous Query

Thanks Val. We are currently using a client node in our desktop gui, but it performs very poorly when the latency to our server nodes is high. We also have other problems, such as when new client nodes join, the whole cluster will pause, which is unacceptable for an end user application. I

Re: Ignite Thin Client Continuous Query

Gordon, Ignite thin client uses request-response model, which is not really suitable for functionality like this. I would never say never, but I think it's very unlikely that thin client would get any feature that imply pushing updates from server to client (this includes near caches, any type of

Re: Fulltext matching

Hi, Thanks for the response. I went ahead and implemented a custom indexing SPI. Works like a charm. As long as Ignite doesn't drop support for the indexing SPI interface this is exactly what we need. I'm happy to create Jira issues and extract this into something more generic for upstream if

Thank you for the answer! It helped. I discovered two functions that can help in controlling the way ignite the attributes onto table aliases. QueryEntity.addQueryField("homeAddress.zip", "java.lang.String", "ha_zip") would allow programmatically define the "homeAddress.zip" field in the table

Ilya, If we won't bother with quotes, then many other tools will stop working, as cache-names-schemas MUST be quoted, but they won't be. By the way, even QLIK will not work with any other schema, except for PUBLIC. So for now, what I propose is not apply quotes to PUBLIC schema. This is the only

Hi, Is there any plan to support continuous query in the Ignite Thin client. This would be very useful for us. Without it, we probably have to use some other technology for serialization and streaming updates to the desktop. Thanks, Gordon This email and any attachments are proprietary &
