What does it mean the difference between "phoneHomeIntervalInSecs" and "handshakeRetryIntervalInSecs" ?

Hi Splunkers,

I cannot understand the difference between "phoneHomeIntervalInSecs" and "handshakeRetryIntervalInSecs" .
Of course, I've already read READMEs as following.

phoneHomeIntervalInSecs = <integer in seconds>
    * Defaults to 60.
    * This determines how frequently this deployment client should check for new content.

handshakeRetryIntervalInSecs = <integer in seconds>
        * Defaults to phoneHomeIntervalInSecs
        * This sets the handshake retry frequency.
    * Could be used to tune the initial connection rate on a new server

Both attributes commonly are related to the intervals to Deployment Server.
Why do we need to be two attributes ?
What situations did you expect to use two attributes differently ?

Thank you for your help.

Based on that doc excerpt, phoneHomeIntervalInSecs handles how often a deployment client will phone home once connected, and handshakeRetryIntervalInSecs handles retried while trying to connect.

As for scenarios for different intervals, when serving a lot of clients through a single deployment server you may want to increase the phoneHomeIntervalInSecs, but possibly keep the handshakeRetryIntervalInSecs low to avoid long initial connections.
