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.
