BackendService

trait BackendService extends AnyRef

A BackendService in Kyuubi architecture is responsible for talking to the SQL engine

1. Open/Close org.apache.kyuubi.session.Session
2. Operate org.apache.kyuubi.operation.Operation
3. Manager org.apache.kyuubi.session.Sessions via SessionManager
4. Check OperationStatus
5. Retrieve org.apache.kyuubi.operation.Operation results and metadata
6. Cancel/Close org.apache.kyuubi.operation.Operation
