Igniters, Turns out, that we are sending a lot of irrelevant information in discovery messages. Some messages contain *TcpDiscoveryNode* objects, which in turn have such attributes like *PATH, java.class.path, sun.boot.class.path, java.library.path, org.apache.ignite.jvm.args, *etc. Some of these attributes may contain huge strings, that can sum up to megabytes of data.
It was noticed by a user on our mailing list: http://apache-ignite-users.70518.x6.nabble.com/Connection-problem-between-client-and-server-td19243.html In his case these huge messages make discovery process really slow. I think, we should filter-out such attributes, because they are not used anywhere, but make messages grow enormous and slow down discovery. We could include only user-defined and internal attributes + a fixed set of environment variables. What do you think? Denis
