Michael Armbrust commented on SPARK-2594:
-----------------------------------------
Seems pretty reasonable. A few notes:
- I'd call the operators CacheTableAsSelect as AddCacheTable sounds more like
you are caching a base table, not some arbitrary query.
- You'll also need to create a new physical operator (SparkPlan) to do the
work instead of doing the work in the planner. This operator will likely want
to inherit from Command.
- There a question of what the result of running this command is (i.e. the
number of rows cached? an empty result?)
- Is the caching eager (i'd vote yes probably?)
