Hi Semyon, we are using Ignite 2.8.1. That being said, could Ignite really be using some behind the scenes optimization which allows for a value instance to be re-used between multiple EntryProcessor runs? Kamil On 5/17/21 11:45 AM, Данилов Семён wrote: I tried reproducing your issue but

Hi, since Java 11 is not only about new features but also about new licensing terms and new release schedule, I would like to ask about the long term goals of the Apache Ignite project. Question 1: With the new Java release model, it seems Oracle will provide security fixes and backports to

Hi, there were multiple issues, one of them being shared and overloaded disks on a hypervisor. That being said, I am not sure if the problem disappeared completely. The node was up since then. The dataset is some 40 GB "bootstrapped" from Kafka. I would need to play with it more, but don't

Are you getting "GC Overhead limit exceeded" OOME? I think you could always move IGFS data block cache off heap if it is not the case already. I am wondering why you've set block size to 4 GB for Ignite when HDFS stock configured block size is either 64 MB or 128 MB. Have you tried to set
