             Summary: [ML] Add hart beat tracker to DistributedInfModel
                 Key: IGNITE-11163
                 URL: https://issues.apache.org/jira/browse/IGNITE-11163
             Project: Ignite
          Issue Type: Improvement
          Components: ml
    Affects Versions: 2.8
            Reporter: Anton Dmitriev
            Assignee: Anton Dmitriev
             Fix For: 2.8


Currently we have DistributedInfModel that allocates resources across the cluster and relies on close() method to release them (it implements AutoCloseable). It works well in case client node works correctly. If it doesn't resources might stay allocated and so that we'll get a memory leak.

To mitigate this risk it's proposed to add hart beat mechanism that will track if client is alive or not from server (service) side.
