jackjlli opened a new pull request #3568: Add guava cache to cache table schema 
in pinot broker;
URL: https://github.com/apache/incubator-pinot/pull/3568
 
 
   This PR adds a guava cache to cache table schema in broker so that 
non-existence column check can directly be done on broker side.
   
   If the cache contains the table schema, just simply returns the schema and 
compare against the columns appeared in the query.
   Otherwise, the cache loads the schema asynchronously. 
   
   If there're columns in the query missing in the table schema, broker emits a 
broker metric and returns an exception back to the client.
