Apache Spark reassigned SPARK-13696:
------------------------------------
Assignee: Apache Spark (was: Josh Rosen)
> Remove BlockStore interface to more cleanly reflect different memory and disk
> store responsibilities
> ----------------------------------------------------------------------------------------------------
>
> Key: SPARK-13696
> URL: https://issues.apache.org/jira/browse/SPARK-13696
> Project: Spark
> Issue Type: Improvement
> Components: Block Manager
> Reporter: Josh Rosen
> Assignee: Apache Spark
>
> Today, both the MemoryStore and DiskStore implement a common BlockStore API,
> but I feel that this API is inappropriate because it abstracts away important
> distinctions between the behavior of these two stores.
> For instance, the disk store doesn't have a notion of storing deserialized
> objects, so it's confusing for it to expose object-based APIs like
> putIterator() and getValues() instead of only exposing binary APIs and
> pushing the responsibilities of serialization and deserialization to the
> client.
> As part of a larger BlockManager interface cleanup, I'd like to remove the
> BlockStore API and refine the MemoryStore and DiskStore interfaces to reflect
> more narrow sets of responsibilities for those components.
