Subject [jira] [Comment Edited] (IGNITE-5464) DML: Can not insert arrays
Date Tue, 13 Jun 2017 00:09:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-5464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16047256#comment-16047256

-----------------------------------------------------------------------

I've done a quick investigation. This happens because Ignite treats all non primitive arrays
declared in query entity as {{OTHER}} (i.e. *Object*) when preparing {{CREATE TABLE}} triggered
by cache registration while H2 on {{PreparedStatement.setObject}} call internally always treats
arrays as such, that's why this internal error of type conversions occurs. Will focus on this
when I'm able to.
