hashCode functions using multiply method

[Albert]

Hi ,
I've noticed a lot of the places, calcite codes is using something like
this:

result = 31 * result + (body != null ? body.hashCode() : 0);

using multiply in hash code calculation probably isn't best practice.
something like shift operator should be more efficient.  since the project
is already depending on guava, why not using their hash code utils ?


thanks.

Fwd: New Apache visual identity is live --please help share the news!

[Julian Hyde]

Hey Calcite developers,

We will need to update our site by May 9th but let’s try to do it this release. 
I’ve logged https://issues.apache.org/jira/browse/CALCITE-1070 
. Would anyone like to take 
this on?

We don’t have many images to upgrade (see 
https://github.com/apache/calcite/tree/master/site/img 
) but we could be 
creative and use the logos in more places on the site.

Julian
