If a cluster with multiple nodes and two replicas experiences a network-related disconnection on one of the nodes, it can lead to an abnormal cluster state where data queries may fail without generating an AerospikeException?

[Server 6.0+](https://enterprise.aerospike.com/enterprise/download/server/notes.html#6.0.0.0) changed the query APIs which allow allow a client which supports the use of these APIs detect if it can’t retrieve all records and propagate the appropriate exception to the application layer.

> - [AER-6500] - (QUERY) Enhanced secondary index queries: query by partition, paginate, throttle, apply quotas.
