> Log retention settings can be set it in broker and some properties can be overriden at
topic level. 
> |Property |Default|Server Default property| Description|
> |retention.ms|7 days|log.retention.minutes|This configuration controls the maximum time
we will retain a log before we will discard old log segments to free up space if we are using
the "delete" retention policy. This represents an SLA on how soon consumers must read their
data.|
> But retention.ms is in milli seconds not in minutes. So corresponding *Server Default
property* should be *log.retention.ms* instead of *log.retention.minutes*.
> It would be better if we mention the if the time age is in millis/minutes/hours in the
documentation page and documenting in code as well (Right now, it is saying *age in the code*.
We should specify the *age in time granularity).
