Re: Ignite 1.6.0 suspected memory leak from DynamicCacheDescriptor

What do you mean by "embedded instances"? if it's org.apache.ignite.Ignite object then we have two, one for each .war application deployed. And what do you mean by "not properly stopped and / or disconnected"? The application call org.apache.ignite.Ignite.close() only when Tomcat shutdown. What if

Re: Server/Client Nodes and classes

CacheStore can be called on client node, in particular if TRANSACTIONAL cache is used. Transactional cache updates the store from a node which coordinates a transaction which is usually a client. This is not needed for ATOMIC caches though and can be improved, we have a ticket for this [1]. For no

Server/Client Nodes and classes

I am having the following situation: I have a 4-node cluster with write-through enabled using an in-house developed MongoDB Cache Store. The spring configuration xml file for the servers include beans for the mongo client, mongo codecs, ignite caches stores, etc. I can successfully start the 4-node

Re: Index wont't be used with QueryEntity configuration

Re: Apache Spark & Ignite Integration

First of all, I'm not sure how it works with Dataframes. Since we don't have Dataframe support yet, only RDD, using Dataframe can potentially not work as we expect (I don't have enough Spark expertise to tell if this is the case or not). The only way to check this is to create tests. Other than th

Re: Encyrption of Data at REST in Apache Ignite

Encryption between nodes is possible, but it's enabled separately from REST [1]. Encryption of stored data is not supported out of the box, but you can try to use CacheInterceptor [1] to support this. Note that it will break SQL query execution, so if you're going to use them, I don't think encryp

Re: Are IgniteCache instances thread-safe?

Hi, Yes, all Ignite APIs including IgniteCache are thread safe and it's OK to use it concurrently from multiple threads. Actually, calling Ignite.cache() method does not create a new instance, but returns an existing one, so you will end reusing the same instance anyway. -Val -- View this mess

Thanks for reply first of all. Well I had this in back of my mind but it will be like duplicating the data which we already have in other cache(trades cache which I am currently querying). So other way I can think of is using spring scheduler with 1 minute fix-rate and check if any item moved to S
