             Summary: UPSERT an empty array by sql
                 Key: PHOENIX-2777
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2777
             Project: Phoenix
          Issue Type: New Feature
            Reporter: Powpow Shen


ARRAY type field can be inserted by `ARRAY['blah']` which has ARRAY_LENGTH 1, 
and  it can also accept `NULL`. But it would be great if it can also accept 
`ARRAY[]`, so `ARRAY_LENGTH` can be 0.
