Github user kishoreg commented on the pull request:

    Then a better api, is to provide a Filter api right.
    similar to File.list(dir, FileNameFilter) we can have a MessageSendFilter which has accept
method that returns boolean
    within Helix, we can invoke this method and caller has the option to say true or false.

> 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.
