Oleg Danilov created SPARK-21121:
------------------------------------
Summary: Set up StorageLevel for CACHE TABLE command
Key: SPARK-21121
URL: https://issues.apache.org/jira/browse/SPARK-21121
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 2.1.1
Reporter: Oleg Danilov
Priority: Minor
Currently, "CACHE TABLE" always uses the default MEMORY_AND_DISK storage level.
We can add a possibility to specify it using variable, let say,
spark.sql.inMemoryColumnarStorage.compressed. It will give user a chance to fit
data into the memory with using MEMORY_AND_DISK_SER storage level.
Going to submit PR for this change.
