Memory utilization of Indexes in ignite

Hi All, I have some open questions about memory utilization of indexes in ignite. So here is the scenario. I have created one cache(CACHE_1) with following props: And i am loading 5GB in CACHE_1. So as per our configs 1 GB data is residing in offHeap and remaining 4GB is going in swap. Now m

Re: ComputeTask is including Nodes for ComputeJobs prematurely

Hi Val, "Prematurely" in this case is a Node not fully initialized. In a nutshell, Ignite is started, enters the "discovery set", but further things must happen for it to be ready to do computation (take real load). When the Grid is initially started, this is pretty easy to control -- we can gate

Re: Can JAVA API SqlQuery query a cache create by SQL DDL?

Re: ComputeTask is including Nodes for ComputeJobs prematurely

Hi Chris, Can you define "prematurely"? What exactly is required for a node to be ready to execute jobs? From Ignite perspective, it is ready as long as it's in topology on discovery level, and that's when it starts receiving requests. BTW, with AdaptiveLoadBalancingSpi you can implement custom A

Hi, We are using Ignite’s Compute Grid. And mostly, it is working beautifully. But there is one glitch I need to work around. AWS, Nodes come and go. And when a new Node joins the existing Grid, it is given ComputeJobs before it is actually ready to handle them. In our infrastructure, a Node an

You should use a driver from 2.2 too if you use nodes of version 2.2. You get "Table exists" error, because table is successfully created by the previous query. Error "Failed to find query with ID:[xx]" generated when ODBC statement is closed after execution of query that produced empty result set
