Hello Sanjiv,
It is a simple select with no filters or conditions and a few casts going
against a database table. Can’t see how it could be possible to improve the
query. Drill will ask for the whole table.Are you accessing the data directly
in Drill through the cmd-line or using the web-ui
Hello Per,
I (not in any way related to MapR engineering) used to develop an idea of a
plugin for XML that is using on-the-fly behind the curtains conversion to JSON
to utilize all the goodies Drill has for JSON but due to a stumbling block (XML

show tables in ., and describe should possibly provide
what you would like to see.
It works on my DB2 at least so please try and see if it works for you as well.

Please look at the plan generated by Drill:
explain plan with implementation for SELECT… (An idea is to test the generated
SQL in the plan in the DB to see what it does)
One idea is to try to put one of the tables in a sub select table where you
actively rename the column.

Hello John,
I assume you are talking about Zeppelin -> Drill? I’ve think I’ve seen it done.
Let me check with the person I believe did what you ask for and ask how he did
it. I think it is somewhat convenient to have one and the same ”tag” for all
statements that goes against jdbc and just
Hello Sanjiv,
My personal unqualified guess as a regular user of Drill is that you have to
write a custom authenticator to get it to talk to the Windows security
framework.

Experimental plugins:
I strongly believe in the open architecture offered by Drill, and I would
welcome a plugin dictionary separated from core Apache Drill where
"experimental" and / or even commercial plugins could be shared. (similar
to how Spark is dealing with packages) I believe experimental

Hello,
I am trying to use the JDBC plugin with DB2 and have some issues:
I am connected to a particular database using the DB in the JDBC url.
Thing look good:
I can see metadata and I can interrogate tables:

I am messing about with refining my XML parser for Apache Drill, and I would
like to make a simple cmd-line interface towards the XML parser i built (which
is not dependent on any Drill code, but used by Drill in my plugin), in the
same jar, by providing a simple main making it possible to

My code is based on easyformat stuff (if remember correctly) public class
XMLFormatPlugin extends EasyFormatPlugin, but I wouldn’t for
the world be able to explain how it works :)

Hello Scott,
What you typically do is that you decide which separator will give you the most
granular split (in your case comma) and then use SQL constructs to further
transform the returned columns of the set to the structure you would like to
have. In SQL you can always create additional
I’ve seen it as well. My unqualified guess is that the engine gets confused
with multiple databases named INFORMATION_SCHEMA and which makes it combine
metadata from two different engines. Gets the metadata of a table from one and
tries to use on the other…

Hello Daniel,
Filters and joins are pushed down i.e. filters on column data. Limit is a
special keyword not always supported by a database (different syntaxes for
quite many databases) and as such I don’t think the push down rules works for
that.

Hello Nirav,
To my knowledge (just a user so I don’t have any deep insights) there’s no such
functionality as of now included in Apache Drill. It could be added but focus
has been on getting data from RDBMS in a convenient way rather than moving data
to RDBMS.

Hello Drill Users,
A few weeks ago i had the pleasure of writing a small SAX parser for XML that I
was using in Storm to convert XML to JSON.
Later I decided this would be great to put into Drill, mostly as a work around
for the fact that Drill does not have native support for XML yet. With some
