Subject [jira] [Commented] (HIVE-8004) Add Case-Sensitivity to Column Names
Date Fri, 05 Sep 2014 23:19:28 GMT


David Beveridge commented on HIVE-8004:

I've been thinking over the same thing myself (where we could, as part of
SerDe, have a Transform function that would encode the data in a
hive-friendly way (such as the hex value of the string)

Of course, that means that queries couldn't use the data directly, which
would be a pain--querying for
parser.imageimportnames.736f6d654261645472616974  = "true", rather than
parser.imageimportnames.someBadTrait = "true", (or some equivalent
mechanism ).

Perhaps it would be worthwhile to measure the interest in this in the
field? We certainly might be an edge case . . . .

> 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
