merlimat opened a new issue #655: Documentation for "Set retention policy" has 
URL: https://github.com/apache/incubator-pulsar/issues/655
 
 
   In the [Message retention and expiry
   ](https://pulsar.incubator.apache.org/docs/latest/advanced/RetentionExpiry/) page, we are explaining that `set-retention` can be invoked with either `--size` , `--time` or both, though the only allowed option is to pass both.
   
   The meaning of the size is to give a max retention size after which data will start to get discarded, even though the time period has not expired yet. 
   
   This is to protect in cases where the "time" was wrongly estimated, or a big increase in traffic would require an unexpected (and possibly unavailable) amount of storage capacity.
