Possible dead lock when number of jobs exceeds thread pool

I am testing an aspect of a POC I have written in C# to determine how well it performs when processing multiple tasks at one time. I’m using Ignite 2.2. Briefly, a client node sends a request to a server node for a list of items. Each of the items requested is send back to a listener in the

Re: Persistence store(MSSQL) using cross-platform c#(Ignite Client windows) and java(Ignite Server linux version)

Does this same approach will work if I have used ignite client as SQL api instead of c# api ? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Persistence store(MSSQL) using cross-platform c#(Ignite Client windows) and java(Ignite Server linux version)

Hi JP, Please let me first explain some basics: Ignite is implemented in Java and presently all other APIs including .NET are "wrappers" of the Ignite JVM. When you start your .NET node, it automatically creates an Ignite Java node and talks to it using some thin JNI layer for .NET/Java

Hi, > c# as Ignite client in windows machine. > The standalone servers in Ubuntu. > .NET cache store Cache store defined in C# code requires .NET on every cache node. Your servers are on Ubuntu and are Java-only, so .NET code can't run there. Some functionality is limited in cross-platform

Re: Job Listeners

Hi Chandrika, Is it possible for you to share your Ignite task implementation? Or are you just running the above example I created? It looks you have some deadlock and it is hard to guess without having the code.

Re: Persistence store(MSSQL) using cross-platform c#(Ignite Client windows) and java(Ignite Server linux version)

Hi, Please can you give more details: - What exactly your issue is? Can you copy all the error output? - Are you using Microsoft SQL server for persistence? - What API does your C# client use to work with Ignite with the persistence enabled? Is it C# API or SQL or something else?

Re: Job Listeners

Hello Alexey, Thanks for the valuable information, i hare tried executing a list of dependent tasks using a DAG using session.setAttribute("COMPLETE",true), and it is working fine as long as there are three nodes, cause there are 3 or less parallel tasks to execute. But when i run the same code

RE: Trouble to connect to ignite cluster on kubernetes

Thanks for your replies! This suggestion doesn't suit me, if I correctly understand what do hostNetwork=true, then I should have one ignite pod in one kubernetes node. In one real kubernetes node I have a few ignite nodes in different namespaces, and I use ignite like as kubernetes service

Re: Question about number of total onheap and offheap cache entries.

I mean in the sixth column "Size" of last chart of "cache -a" command, the "Heap" entry count is not 0. As the above picture shows. But in the cache summary chart, the on-heap entry count is 0.

Adding to the same question, can I see the off heap memory usage in Visor or Web console? I see on-heap memory size in Web console. On Tue, Oct 3, 2017 at 8:28 AM, Alexey Kuznetsov wrote: > Hi, > > Take a look at documentation: https://apacheignite.readme.io/docs/ >

Re: Question about number of total onheap and offheap cache entries.

But my on-heap entry count is still not 0 here. As I didn't set onHeapEnabled=true, the value should be false in default, right? So is this a visor bug that the on-heap entry count is not 0? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
