June 2007

These release notes are replicated for historical purposes only. The release is not supported anymore.

Release “2007-11-22” (released on Nov 22 2007) consists of the following updatedparts MonetDB Clients 1.20.2, MonetDB5 Server 5.2.2, MonetDB5/SQL 2.20.2. This release is a bug fix release, covering the following items:

  1. Clients: The APIs for python, perl and php have been synchronized by the latest state of the Mapi protocol and implementation. JDBC contains a non-blocking IO fix for slow network connections.
  2. A performance fix of the group module. Improved grouping functionality significantly through a better estimate of the intermediate sizes.
  3. The MonetDB/SQL embedded version has been made to work again.
  4. Memory leakage in both the Server and SQL module have been addressed.

Release “2007-10-17”

(released on Oct 22 2007) consists of MonetDB Common 1.20, MonetDB Clients 1.20, MonetDB4 Server 4.20, MonetDB4/XQuery 0.20, MonetDB5 Server 5.2, MonetDB5/SQL 2.20. This release marks a long summer of mostly core software development and maintenance. The restructuring of the source tree was partly successful. Semantic dependencies amongst packages, however, forced us to release more components together than originally planned. Close interaction with some large users provided valuable input for bug fixes and performance improvements.

SQL We added a way to bulk request sequence numbers. When loading (copying) data into tables which have an auto_increment (or alike) column lots of time was spend in the many calls to get all the sequence numbers (observed a performance in crease of about 10x when loading pieces of 100K rows) TINYINT was added to the standard repertoire. We changed how selections over multiple columns of a single table are handled. Furthermore, several bugs stemming from large-scale deployment have been resolved.

XQuery In the XQuery area many issues have been dealt related to the transaction safe update functionality. Furthermore, a value based indexing scheme has been added to speedup the search.

Clients The mclient utility has undergone a major overhaul. It moved from a Spartan rendering of SQL results towards a more user friendly tabular rendering on ascii terminals. In passing, the option structure and command options has been stratified and extended with a few use full functions, e.g. piping the tabular result as a CSV to an external program. Use the –help for an overview.

MonetDB 5 Merovingian has been added as the gatekeeper of all SQL database services in a particular farm. It redirect clients to the proper connection. The accompanying Monetdb toolkit provides a textual frontend for assessing the status of a collection of MonetDB servers.

MonetDB 4.18, MonetDB/XQuery 0.18, MonetDB 5.0, MonetDB 5.0/SQL 2.18. The Mars release marks the official release of the MonetDB server 5 line as the basis for future investments in application development. This affects first and foremost the maintenance of SQL code base, where the MIL version is not being maintained actively anymore by the MonetDB team. A synopsis of the major improvements

  1. implementation of delete/update with cascading
  2. PSM procedure call implementation
  3. support for polymorphic functions
  4. autoloading of sql scripts upon server restart

WarningThe SQL catalog structure has been changed, which requires a database dump before you install the new version.WarningThe old Window installers do not always remove MonetDB DLLs. You may have to manually remove them from system32 before (re-)installing the new version. It concerns:

  • libstream.dll
  • libmutils.dll
  • libMonetODBCs.dll
  • libMonetODBC.dll
  • libMapi.dll

MonetDB XQuery XQuery Update Facility has undergone a large series of stress tests to improve correctness, performance and robustness under concurrent updates. In many areas the functionality has been improved:

  1. a completely revised and enhanced type checking code
  2. the administrative console for XQuery
  3. automatic use of value indexing
  4. improved and extended XRpc functionality (javascript library)
  5. all XPath axes looplifted (siblings will come soon)
  6. Intel-based native Windows build (i.e., 64-bit)

This release containsPF/Tijah,, a text search extension for XQuery. It provides a flexible environment for setting up search systems by supporting out-of-the-box solutions for common tasks, like index creation and result ranking of XML elements. Work continuous on the algebra version compiler and its SQL backend code generator.Release model The months passed since the bug-fix release of February 2007 showed that the MonetDB product family has grown to a size that more frequent releases are only possible if we continue our decomposition process. The SQL and XQuery release dependencies have now been cut. Source distribution The Super Source Tarball has become a stable means to access and install the packages on Linux platforms.
