Re: Ignite 2.3 still not support group_concat

Hi James, Nice catch! Yes, it's not supported yet. Looks like it was mistakenly added to the documentation in version 2.3. Just suggested deleting this page from the doc. It should be removed soon. Regards, Evgenii 2017-11-02 4:53 GMT+03:00 james wu : > The new ignite 2.3

Hey, Which exception threw there? Could you share stacktrace? Does here really client reconnects to the same cluster, or it was after the server node was restarted? Evgenii 2017-11-09 18:34 GMT+03:00 guillMelo : > Hello, > I am sorry If I am not being clear, my goal is

Re: How to scale out Ignite?

Hi, 1. What do you mean by "when"? I'm sure that you can find all needed information here: https://apacheignite.readme.io/docs/service-grid. Also, I don't understand why do you think that affinityCall is dangerous. 2. Well, everything should scale automatically. For a partitioned cache, you can

Re: IP finder returned empty addresses list on Yarn

Hi, To check if Ignite uses this default-config.xml file, you can just break this xml(for example remove closing of tag). If Ignite will still start without problems, then it uses a different config file. Also, do you really need to use MulticastIpFinder? I think you can use Static IP Based

Well, then you can start other Ignite cluster with enabled persistence and move data from the first cluster to the second one. Evgenii 2017-12-01 18:31 GMT+03:00 Marco : > yes, that way works, but the question is how to output 30m out without > restart? I didn't enable

Re: the balance between read and write.

I don't understand how it will work in your case if you will have 2 separate clusters. I think you can just add more machines to the cluster and this problem will be resolved. Evgenii 2017-12-01 18:35 GMT+03:00 Marco : > is that worthy a try that initate 2 ignite

Re: Index performance

Hi, Please share benchmarks code, it's hard to understand why you can't load CPU for 100% without your code. But I see one thing, that definitely could lead to performance problems - you've set - this could lead to a lot of context switching since every query could be executed in 48 threads.

Re: Question Ignite Memory Consumption / Object size (Apache Ignite .NET)

Hi Mario, You have 7 indexed fields, I think it could be a reason of high memory consumption. As for estimating memory size - I would recommend loading various sized data several times and measuring Memory consumed by it. It will help you to understand approximate needed memory size. These

Re: Modify the underlying IgniteRDD Cache

Well, all changes in Ignite cache (regardless whether they were caused by another RDD or external changes in cache) will be visible to RDD users immediately. Most possible this happened because you set different types for keys and values in ignite native api and ignite rdd. I've checked this
