Hello, first let me wish you a happy new Year!
I am currently working with replicated and local caches and I observe a strange behavior in my application. I do not know whether it is related to my application or to ignite at this point and thus looking for information. I have a REPLICATED cache that is loaded once and for all and then have a job running on the partitions and filling in a LOCAL cache. On one K8S node, it takes 61s but when I add a second node it goes up to 168s for the same amount of work. These number are not significant in itself but I fail to understand why it would be case. If anything I expected a speedup since I double the number of cores and consume locally (because replicated) and put locally (because LOCAL). Interestingly enough, with one node the CPU is at 100% and with 2 it goes down to 30% which is usually the sign for IOs. Could you please: 1)Confirm that my assumption is correct and that reading from a replicated cache that is not modified after loading and writing to a LOCAL cache should be pretty linearly scalable to the number of nodes (ignoring the initial rebalancing of the partitions) 2) someone tell me if we expect a lot of (technical) messages exchanged between the nodes in this configuration. Thanks a lot for your help -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
