Use of rdd.zipWithUniqueId() in DStream

[Sourav Mazumder]

Hi All,

I'm trying to use zipWithUniqieId() function of RDD using transform
function of dStream. It does generate unique id always starting from 0 and
in sequence.

However, not sure whether this is a reliable behavior which is always
guaranteed to generate sequence number starting form 0.

Can anyone confirm ?
