Pravega allows users to store data in Tier 2 as long as there is storage capacity available.
But sometimes, users may not be interested to keep all the historical data related to a Stream.
Instead, there are use-cases in which it may be useful to retain just a fraction of a Stream's data.
For this reason, Streams can be configured with StreamRetentionPolicy.
