Hi Ramond, Node.Consistent ID by default is the sorted set of local IP addresses and ports. This field value survives during node restart.
At the same time consistent ID may be set using IgniteConfiguration.setConsistentId() if you need to specify it manually. I'm not sure how to write in C# syntax, but I am pretty sure it may be configured.
