Re: Apache Ignite 2.9.0 RELEASE [Time, Scope, Manager]

Alexey, We've benchmarked the whole set of tests tonight in both persistent and in-memory modes on the current 2.9 branch (with minor tracing optimization merged). And on our environment, we've got 0-2.5% drop for each benchmark compared to 2.8.1. I think it is an acceptable result. So, I'm ok wit

Re: Thin Client ping operation?

Personally I believe that public API still can be helpful, as it gives user an ability to check connection in the specific point in time, even if automatic ping is implemented (which is more complex and hard-to-maintain feature by the way). Not sure there should be "ping" in API though, maybe some

Escaping dots in cache metric names

Hi, guys! Cache names may contain dots, but in metic names we create hierarchy with dots. So with the cache name "Person.statistic" we will have a metric "io.statistics.sortedIndexes.SQL_PUBLIC_Person.statistic._key_PK" which is not obvious what is a cache name and what is next hierarchical elemen

Re: Escaping dots in cache metric names

Hello, Alex. We can’t restrict dot in the cache name because it will break backward compatibility of Ignite. > 15 сент. 2020 г., в 16:38, Alex Kozhenkov написал(а): > > Yeah, that would be even better for all cases. > > вт, 15 сент. 2020 г. в 15:51, Ilya Kasnacheev : > >> Hello! >> >> This

Re: Re[4]: Thin Client ping operation?

Zhenya, sure, let me explain. Health checks are a common practice in modern deployments, quote [1]: "Health probes can be used by container orchestrators and load balancers to check an app's status. For example, a container orchestrator may respond to a failing health check by halting a rolling de

Re: [DISCUSSION] Add autocompletion for commands in control.sh

Hello, This idea looks great in my opinion. I agree that a more common approach would be better but I am the same as Kirill haven't found the better one. So in my point of view, this library is better than nothing, and if nobody will recommend a different one we can take picocli right now. --

How to eliminate frequent restarts - maybe changes with Ignite 3.0?

Hi Everyone, I'd like to start a discussion on how to eliminate the need to restart the entire cluster whenever configuration changes need to be made to caches. The need to deactivate and restart the entire cluster every time config changes must be made has caused problems with our ability to scal

Re: How to eliminate frequent restarts - maybe changes with Ignite 3.0?

Hi Devin, What are the exact configuration changes that force you to restart the cluster? What is your process of onboarding a tenant? The reason I'm asking is that adding new caches should not require a cluster restart, even in the current version, but it's possible that you're hitting one of th

Re: Apache Ignite 3.0

For what it is worth, we use messaging in Ignite to provide grid notifications for various purposes. These might stimulate compute operations in the message recipients, but they don't represent compute. If messaging is removed, how would Ignite provide the ability for a node to listen to events wi
