             Summary: Add mapping from Byte[] to VARBINARY and Character[] to 
VARCHAR in Java UDF
                 Key: CALCITE-7186
                 URL: https://issues.apache.org/jira/browse/CALCITE-7186
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.40.0
            Reporter: Yu Xu
            Assignee: Yu Xu
             Fix For: 1.41.0


Java user-defined function (UDF) UDF functions with *Character[]* and *Byte[]* 
return types are recognized as {*}OTHER{*}, but UDF functions with *char[]* and 
*byte[]* return types are recognized as *VARCHAR* and {*}VARBINARY{*}. 
*Character[]* should be consistent with {*}char[]{*}, and *Byte[]* should be 
consistent with {*}byte[]{*}.
