             Summary: [DOCS] Document recommendation to use VARCHAR or STRING 
instead of CHAR(N)
                 Key: IMPALA-7291
                 URL: https://issues.apache.org/jira/browse/IMPALA-7291
             Project: IMPALA
          Issue Type: Improvement
          Components: Docs
    Affects Versions: Impala 2.12.0
            Reporter: Balazs Jeszenszky


CHAR(N) currently does not have codegen support. For that reason, we should 
recommend customers to use VARCHAR or STRING instead - the gain of codegen 
outweighs the benefits of fixed width CHARs.
