2. If you want the Ignite cluster to be authoritative about caches, then you should define them in the XML configuration or deploy your servers with code which can look up the intended cache configurations and implement them. If you have specific ideas how you would like to implement this, maybe yo

2. I understood, You are talking about placing the cache in a persistent data region and at the same time enabling the read-through, write-through caches mode. Thank you. This is, of course, a double penalty, but I’ll think about it and test this mode. 5. It seems that Ignite has refocused on

Most of the metrics are about the node you're talking about rather than the cluster as a whole. When you're talking about a distributed system, is a "get" a client or a server operation? A bit of both, right? On Mon, 29 Jan 2024 at 14:05, Godfather wrote: > Hi Community , > I have configured my
