---------------------------------
Labels: bulk-closed (was: )
> Compress complex-typed data (e.g., Array) in InMemoryRelation
> -------------------------------------------------------------
>
> Key: SPARK-16141
> URL: https://issues.apache.org/jira/browse/SPARK-16141
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.1
> Reporter: Takeshi Yamamuro
> Priority: Minor
> Labels: bulk-closed
>
> The current implementation only compress native typed data (e.g., int, float,
> ...) in InMemoryRelation. However, there is a room to compress complex typed
> data, e.g., Map, Struct, Array to save heap space. Particularly, Array is
> frequently used in machine learning use cases described in SPARK-16073 and
> the compression seems to help.
