Impala's performance could be the difference between "Cloudera Standard" and "Clouder Enterprise"?

[#1]

Dear cloudera developers.

I have question about differences between "Cloudera Standard" and "Cloudera Enterprise".

- What is the "Enhanced cluster statistics"? (I found this feature in the next document).

- General performance of "Impala" could be the difference between "Cloudera Standard" and "Clouder Enterprise"?

Perhaps the Cloudera Enterprise page from the main website will be more helpful.

One of the items included on that page is the below PDF explaining the differences which should be the most up to date. The document you linked to is for Cloudera Manager 4.7.3. while the current version is 5.5.1.
