Re: What will happend in case of run out of memory ?

Correct, evicted data can be loaded from a cache using cache.get/getAll like methods. However note that if you run a SQL query and there is some evicted data in a persistent storage then it won’t be considered because SQL engine doesn’t trigger the storage for data loading. — Denis > On May 1

Could it be because of the cache store implementation classes I use? That some of them trigger this exception? I will try the latest nightly build you've mentioned, and report you about the results. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Clear-cache-fro

Re: Unexpexted exception

Hi, thank, now it's working, but now I have other problem. All is working but my session isn't saved. I have HttpSession object and in one servler setting an attr and in other servler I trying to get this attr and it's not there. I checked in debugger - my session is WebSession from ingniter.

Re: What will happend in case of run out of memory ?

Ok, so eviction policy allows configure what data should be dropped out from cache. If it is need to get dropped data, they will be loaded from datastore (for example postgresql). 1. Eviction policy protect against out of memory (data always may be loaded to cache). Am I ok ? -- View this m

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

Thanks for your answer, nevertheless I still don't understand. I know that nodes in ignite are launched in jvm. It seems to me that off heap make it possible to cache large dataset (such large as RAM). Why it is not possible with on heap ? Why off heap is faster than two others layers ? -

Affinity Collocation - more details

Hello, I am caching underlying database. These data contains: CountryID, TID. Is it possible to use affinity collocation in following way: 1. Rows with the same CountryID are on the same cache node. 2. Rows with the same CounryID and TID (as second priority) are loaded on the same cache node

Thanks Denis. I think we should try this. Is there an C++ API we could use to get the ignite client node instance from the grid to run SQL queries? Thanks, Arthi -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Client-Connection-to-Ignite-takes-time-tp4739p4870
