Re: Ignite web console

Hi Viraj Rathod, 1. Make sure that you copied "ignite-rest-http" folder from "libs/optional" to "libs". This module is required by Web Console in order to communicate with cluster via REST. Cluster should be restarted if "ignite-rest-http" was not in "libs". 2. Please attach log from Web Agent.

Re: Ignite startu is very slow

Hi, I'd say that 128 partitions should be more than enough for 3 nodes, just try it. Note: you will need to reload all data in caches, because they will have different affinity. Best Regards, Evgenii вт, 4 дек. 2018 г. в 02:36, kvenkatramtreddy : > Hi, > > Please could you suggest the number

Hi, Unfortunately, it's not going to be near future. It's definitely not 2.7 (which was frozen a long time ago), almost definitely not 2.8 (because it would probably take to much time to do and 2.8 is supposed to figure out other stuff related to Java 9+ support). You can always workaround this
