[jira] [Commented] (HIVE-8004) Add Case-Sensitivity to Column Names

["Xuefu Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-8004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14123714#comment-14123714 ] 

Xuefu Zhang commented on HIVE-8004:
-----------------------------------

I can image this task is quite significant. Before we take pain to provide such an option, I'm wondering if whether the use case justifies the effort and complexity. Since the column name is also the data, there might be a way encoding the data such that case in original data matters in the encoded column name.

> Adding an option to adopt case-sensitivity to column names should be considered.
> I will use our own case for consideration:  we are using Hive for both Natural Language Processing queries and hosting data for Genetic Algorithms (and querying traits).
> In both cases, we need to dynamically generate schema to host the data; meaning that the Column Name in Hive is actually data (as well as its value) and, thus, case-sensitivity matters.
