I start an Ignite server first, then start an Ignite client which do some asynchronously operations on cache. But only after several seconds, the operation jammed. Is there anything wrong about my code? public class ContinuousQuery { public static void main(String[] args) {

Re: SqlFieldQueries on property of custom user type

It’s possible to execute queries accessing fields of inner classes. In your example you need to remove “ChildObject” prefix from the query and it will work fine: "select ParentID, ChildID from Parent where ChildID < 10” — Denis > On Feb 20, 2017, at 6:14 AM, davida

Re: Get high throughput for loading data in ignite

Sorry for late answer. Common performance tip described in [1] and [2]. Do you have all your ignite nodes on single machine? Do you use any Virtual Environment like VmWare ESX? Ignite running inside VM can have some performance issues. Also I've notice from screenshot you provide: - almost half
