Re: Help with tuning for larger clusters

Reducing the port range (to a single port) and lowering the IgniteConfiguration.setFailureDetectionTimeout to 1000 helped speed up everybody joining the topology and I was able to get a pi estimator run on 64 nodes. Thanks again for the help, I'm over the current hurdle. Joe Quoting d...@

Re: Performance issue with REPLICATED cache

Hi Yuri, Is there a chance you can create a small github project reproducing this? You don’t need to have 15 caches, I think 1 cache would suffice. If the above is not possible, then we will have to investigate by looking at logs, code, etc., which would take more time. D. On Mon, Oct 26, 2015

Performance issue with REPLICATED cache

Hi All, we are using Ignite 1.3.3 in win server environment. *Caches configuration* Each Ignite node has ~15 caches ~1M records each of Integer-to-Object entries (total memory required ~7Gb), configured as "REPLICATED", readFromBackup flag is set to "true", transaction mode is "ATOMIC", all the

Re: Help with tuning for larger clusters

Thanks for the quick response Denis. I did a port range of 10 ports. I'll take a look at the failureDetectionTimeout and networkTimeout. Side question: Is there an easy way to map between the programmatic API and the spring XML properties? For instance I was trying to find the correct xml

Indexing/Querying of child element fields.

Hi, Is it possible with Ignite to index or query fields of entity children ? An example would be two structures, one embedded into another. When I query for ProductSpecification entity, I'd also like to return catalogId value or possibly search on those fields ? But I couldn't find any relevant do

Re: Native .NET

As far as I can tell, the only potential overhead in Ignite .NET support vs. Java is the JNI layer. However, we have been testing it internally, and in distributed tests (2+ nodes) we have not seen any performance degradation due to JNI. The reason is that JNI overhead becomes largely negligible co

Re: Native .NET

James, Yes, you described Ignite.NET architecture correctly. It provides native .NET API and marshalling layer. All infrastructure-related work is performed by C++/Java code. Vladimir. On Mon, Oct 26, 2015 at 12:52 PM, jamesgibbs100 wrote: > Vladimir, > > Thank you for taking the time to get b

Hi, Joe, >I also haven't been seeing the expected performance using the hdfs api to access ignite. Regarding the slow IGFS, please create another topic for that problem, since this may not be related to discovery issues in large cluster. Can you please send us configs you have used to test IGFS sp

James, My last statement is a bit confusing. What I wanted to say is that normally both Java and .Net spend comparable time on serialization. On Mon, Oct 26, 2015 at 10:38 AM, Vladimir Ozerov wrote: > James, > > Ignite is distributed application and both Java and .Net require > marshalling to p

Re: Native .NET

James, Ignite is distributed application and both Java and .Net require marshalling to pass data between nodes. Therefore, in the vast majority of scenarios .Net has marshalling overhead comparable to Java version. Vladimir. On Sun, Oct 25, 2015 at 8:46 PM, James Gibbs wrote: > Hi there > > I'

Re: Help with tuning for larger clusters

Hi Joe, How big is a port range, that you specified in your discovery configuration, for a every single node? Please take into account that the discovery may iterate over every port from the range before one node connects to the other and depending on the TCP related settings of your network i
