    Helix already have this concept, which is called Criteria, and this field is part of Criteria.
    Other fields contains instance name, partition name, partition state, etc.

> Helix allow messages to be sent to a partition with specific state. e.g. Sending message
to PARTITION_8 whose state is SLAVE.
> However, sometimes user wish the message is sent to only ONE SLAVE rather than ALL SLAVEs,
e.g. A backup message should be sent to only ONE SLAVE.
