Re: Query on Ignite Visor usage

Hi, I don't think that it's related to the commands that you run from Visor, it's more about the way Visor connects to the cluster. Internally, it starts a daemon node, which basically has the same discovery and communication mechanisms as other nodes. So, other nodes will try to communicate with

Re: Apache ignite statefulsets pods abruptly restarts

There is no such thing as "on heap cache only.". It's possible to enable an additional cache level in heap, but it still will be storing all data in the off heap. So, right now you need at least 10.25+8gb+ Checkpoint buffer size for your Ignite node. Evgenii пн, 21 сент. 2020 г. в 09:29, Sanjaya
