7.1.0
Description
As per our discussion on July 19-2021, for the graceful exit of query service, we need query to be added as a topology-aware service.
This is needed for cluster-aware rebalance feature for query, wherein if a node with query service is rebalanced, we want to
1.Complete all queries in progress (instead of shutting down immediately)
2.Wait for the in-flight transactions to complete
3.Not accept any new requests

Kamini Jagtiani Do you need anything else at this point, other than the instructions already provided to Donald to enable topology awareness for Query? Once Donald Haggart confirms things works, I am assuming we may need a bit more work to figure out upgrade/migration. We'll need to smooth transition from pre-7.1 to 7.1 so Query will need to be aware of compat mode and only once cluster is capable operating in 7.1 mode, you should activate topology aware capabilities. Till that point, query must operate in the current mode.
