Github user paul-rogers commented on the issue: https://github.com/apache/drill/pull/1104 I noticed this change when merging with the latest master. What does `DYNAMIC_STAR` mean? The original `WILDCARD` name was more theoretical. How is `DYNAMIC_STAR` different from `STAR` (other than being `**`)? Can we call it `WILDCARD` and `isWildcard()` that the string is `**`, presumably for internal reasons, seems less worth calling out in the name.
