[jira] [Commented] (STORM-2143) Storm SQL provider implementations should convert field names as uppercased

["Jungtaek Lim (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STORM-2143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15562030#comment-15562030 ] 

Jungtaek Lim commented on STORM-2143:
-------------------------------------

It can be done with simply adding function which converts field names to stream, but it's a short term solution , and if we can push down filters to data source, data source itself should handle this.

> When getting column informations from Calcite, they are not case sensitive and all uppercased. 
> Since Storm field name is case sensitive, we should respect 'case insensitive' while handling tuples. If producer just creates tuples with field names to uppercase before filtering and publishing, that makes life much easier.
> NOTE: This should be documented so that following implementations can follow up.
