Re: Running gridgain yardstick

Hi, It creates the 'libs' folder. And I got imported the above project also that you mentioned, but it's still showing the same result! :( Also, to let you know, I'm using cygwin on a windows platform to run the script, could that be any reason for it to not run? -- View this message in

Re: Ignite client near cache conflicts with server distributed cache

There are several options how you can deal with this: 1) define caches in Spring XML configuration of all server nodes and start near caches on clients when needed; 2) start a special client that will initialize all required caches dynamically and stop it after that. The rest of the clients can

Slow data loading and high(very) memory usage issues

Hi, I’m trying to load tSV file size ~six gigabytes (contains ~90 million records) into single Apache Ignite node with allocated heap size = 40 gigabytes. For loading used IgniteDataStreamer. Code and sample (10 records) of data is here: https://github.com/olegskoblya/traffic-loader.git Physical

Re: Ignite WRite Behind

does write behind work without this setting :- cacheCfg.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_ASYNC); Here is my cache setting :- cacheCfg.setReadThrough(true); cacheCfg.setWriteThrough(true); cacheCfg.setWriteBehindEnabled(true);

Re: Ignite WRite Behind

I undrestand that WriteAll will be called per cache. But my undrestanding is this :- 1) There are two configs for write behind 1) No of Entries and Time 2) SO if I make three cache entries in three transaction before the time (which is configured to lets say 4000 ms ) then the writeAll should

Re: Off-Heap Memory - simpler explanation than in docs

Hi, what exactly is not clear? When you create objects in Java, they end up on JVM heap, in managed memory. These objects are subject to automatic garbage collection. Ignite Off-Heap Memory feature stores cache data in unmanaged memory (manual allocation/deallocation, like you do in C and other

Re: Ignite client near cache conflicts with server distributed cache

You can't have on the client node "far" and "near" cache simultaneously. The error message you get on the attempt is pretty self-explanatory. So I see not bug here. 2016-05-05 17:13 GMT+03:00 zshamrock : > Yes, removing definition of the cache from

Re: CacheStore implementation dependencies for Ignite

Hi, Put all your jars into lib folder if you are using standalone Ignite distribution. When you can provide your own config file as described here[1] [1] https://apacheignite.readme.io/docs/getting-started#section-passing-configuration-file 2016-05-05 16:32 GMT+03:00 zshamrock

Re: Error starting c++ client node using 1.6

Hi Vladimir...Yes that is correct. I 1.6 binary that I downloaded from the Jenkins server did not have your change. However 1.6 source I downloaded from git branch has your change. I am building that and see if I can get rid of the error. Thanks, Murthy. On Wed, May 4, 2016 at 4:30 AM, Vladimir

Re: Cache metrics - cache hits and misses are 0, also isEmpty in inconsistent state with getSize

Hi! We have an open issue for this: https://issues.apache.org/jira/browse/IGNITE-369 For now the only way to enable cache metrics - via configuration on cache startup. You may watch issue IGNITE-369 in JIRA and will be notified when it will be fixed. But I'm afraid it will not be fixed in nearest

So, it is not recommended to turn them on in production? Then how you measure you cache overall behavior? Could be it controlled over JMX? -- View this message in context:
