[jira] [Commented] (FLINK-15159) the string of json is mapped to VARCHAR or STRING?

    [ https://issues.apache.org/jira/browse/FLINK-15159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16992227#comment-16992227 ] 

Jark Wu commented on FLINK-15159:
---------------------------------

Currently, VARCHAR is the same with STRING, they are both alias of VARHCAR(MAX_LENGTH), but we suggest to use STRING, because VARCHAR should take a lenght parameter all the time.
