[Monetdb-developers] monentdb autocommit

by 颜勋

Hi all, I use BenchmarkFactory and ODBC to test the monentdb performance. But it seems the default option of monentdb is autocommit, so some test scripts seems not work. How should i change the autocommit option (not only use "set autocommit 0" and just change it in the range of one transaction )? Does anyone know the details(that'are tools, scripts, monetdb enviroment) of TPC-H test in monentdb website? Many thanks~ Regards Yan

[Monetdb-developers] MonetDB/XQuery: reading XML files from TAR archives

by Wouter Alink

Hello devs, Roberto and I yesterday discussed that it would be useful to be able to load (compressed) XML collections directly into MonetDB/XQuery. The attached diff provides a new feature for loading multiple XML docs directly from tar files. Usage: "mclient -lxq -C <colname>" and pass a tarfile via stdin, see example below. My question: is this useful enough to make it into MonetDB? And if so, is the current syntax appropriate. Comments are appreciated. Greetings, Wouter $ mkdir xmlfiles $ echo "<abc/>" > xmlfiles/aap.xml $ echo "<abc/>" > xmlfiles/beer.xml $ tar cf xmlfiles.tar xmlfiles $ mclient -lxq -C xmlfiles < xmlfiles.tar Copying TAR file into collection: 'xmlfiles' Name: xmlfiles/beer.xml Length: 7 Name: xmlfiles/aap.xml Length: 7 $ echo 'pf:documents("xmlfiles")' | mclient -lxq <document updatable="false" url="xmlfiles/aap.xml" collection="xmlfiles">xmlfiles/aap.xml</document>, <document updatable="false" url="xmlfiles/beer.xml" collection="xmlfiles">xmlfiles/beer.xml</document> $

[Monetdb-developers] Announcement: New Aug2009 feature release of MonetDB suite

by Stefan Manegold

Dear all, The MonetDB team at CWI/MonetDB BV are pleased to announce the new "Aug2009" feature release of the MonetDB suite of programs. This feature release is backward compatible with the previous releases (Nov2008 through May2009-SP2). Caveat: When upgrading from a release older than May2009 (i.e., Nov2008 through Feb2009-SP2), you need to move your write-ahead log following the "recommended" instructions for SQL (<http://monetdb.cwi.nl/Development/Releases/May2009/#SQL>) and/or XQuery (<http://monetdb.cwi.nl/Development/Releases/May2009/#XQuery>). More information on the new release is available at <http://monetdb.cwi.nl/Development/Releases/Aug2009/>. The sources and binaries are available at <http://monetdb.cwi.nl/Download/>. Enjoy! The MonetDB team at CWI/MonetDB BV. -- | Dr. Stefan Manegold | mailto:Stefan.Manegold@cwi.nl | | CWI, P.O.Box 94079 | http://www.cwi.nl/~manegold/ | | 1090 GB Amsterdam | Tel.: +31 (20) 592-4212 | | The Netherlands | Fax : +31 (20) 592-4312 |

[Monetdb-developers] Module dependencies in Aug2009 release branch/candidate

by Stefan Manegold

Sjoerd, fellow developers, I just realize the following: (at least) due to my recent changes, (at least) MonetDB4 & MonetDB5 in the Aug2009 release branch (most probably) do no longer compile with an earlier version of MonetDB common (GDK), mainly because I added (for convenience) the assert_shift_width() C macro to gdk.mx/gdk.h . It could well be, that binary build of the latest versions of MonetDB4 & MonetDB5 still work with binary builds of earlier versions of MonetDB common (GDK); at least I'm not aware of any interface changes. Hence, unless we remove the assert_shift_width() C macro, again (and implement its functionlity differently), we'd need to make the upcoming MonetDB-4.32.0 and MonetDB-5.14.0 requiring MonetDB-1.32.0. However, this also changes the dependencies for the binaries. Well, given our regular release cycle, and Windows installers and super source balls that contain "everything", anyway, I don't expect too many users that would like to upgrade only M4 or M5 or sql, while keeping the "old" GDK ... Hence, to be on the save side, I'd propose to update all dependecies in the Aug2009 branch to require part from that very branch (and possibly introduce this as a standard procedure, unless/until we indeed do partial releases). Any thoughs, comments, objections? Thanks!

Is this correct? What about the case where you have a field which ends in \\, such as \\,more data which is two fields separated by a comma.
