Re: Client App Object Allocation Rate
Hello! Okay, that's not very cool. I hope to get some response from development side at this point. Sans reaction, I will file a ticket.

Re: Client App Object Allocation Rate
Hello! I guess that you have EVT_NODE_METRICS_UPDATED event enabled on client nodes (but maybe not on server nodes) It will indeed produce a lot of garbage so I recommend disabling the recording of this event by calling ignite.events().disableLocal(EVT_NODE_METRICS_UPDATED); + dev@ Why do we record EVT_NODE_METRICS_UPDATED by default? Sounds like a bad idea yet we enable recording of all internal events in GridEventStorageManager. -- Ilya Kasnacheev пн, 26 окт. 2020 г. в 19:37, ssansoy : > Hi, here's an example (using YourKit rather than JFR). > > Apologies, I had to obfuscate some of the company specific information. > This > shows a window of about 10 seconds of allocations > > < > http://apache-ignite-users.70518.x6.nabble.com/file/t2797/MetricsUpdated.png> > > > Looks like these come from GridDiscoveryManager - creating a new string > every time.
