We have a ignite cluster of 1 node and a thick client connecting to it. We have a compute job which queries about 400k records and process them and it is a long running job. We observe that the client node is getting disconnected after sometime with below error although I see that the job is still running on the ignite node. Is there a better way to handle this scenario?
