[jira] [Commented] (IGNITE-9453) REST: UUID column type displayed like byte array

["Roman Shtykh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-9453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16602870#comment-16602870 ] 

Roman Shtykh commented on IGNITE-9453:
--------------------------------------

Looks like it's not only about REST.

{{H2Utils.meta()}} calls {{ResultSetMetaData#getColumnClassName}} which returns a Java type.
 I think for SQL we have rather call \{{ResultSetMetaData#getColumnTypeName }}

[~vozerov] what do you think?
