I've been researching a problem where we see a ClusterGroup topology
becoming unexpectedly empty. I have not found anything that is similar to
my case outlined below:
We have some code using the C# client on Ignite 2.8.0 like this:
var _group = _ignite?.GetCluster()?.ForAttribute(_roleAttribute, "True");
There are nodes in the grid (deployed on AWS EKS) that have a local
attribute with the _roleAttribute name set to the value "True", yet this
command sometimes decides that there are no matching nodes. Once it does
so, it does not seem to change requiring a restart of the grid.
In this instance, the _ignite reference may be a long lived reference to
the object returned by Ignition.GetIgnite("GridName") and cached for future
reference. Is this a safe practice, or can the underlying Ingite object
change leaving a long lived Ignite reference containing stale state
information about the grid?
Thanks,
Raymond.
