Raju Bairishetti updated KAFKA-3087:
------------------------------------
Description:
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).
