Interactive Debugging for Python UDFs

In a previous blogpost we introduced Python UDfs (aka MonetDB/Python). With MonetDB/Python users can perform analytics inside the database, mitigating the costs of data transference.

MonetDB mirror on GitHub

As the most observant of you may have already noticed, some time ago we created a GitHub mirror of the MonetDB source tree: After a few months of internal testing we are ready to officially announce it to the public.

On the technical side of things, the primary MonetDB repository remains hosted in Mercurial and the development process for MonetDB is unchanged.

Astronomy and technology

Astronomy and technology inspire each other. Thanks to the latest advances in technology we can build instruments that are not only better than ever before but also totally new in design. This allows us to observe the skies and heavens "from new angles" with unprecedented space and time resolutions. No doubt that technological developments in many fields thrive on the scientific discoveries that these advanced instruments will make. In this regard, the entanglement of the two disciplines has delivered us a lot over the past 400 years.

MonetDBLite for Python

We are releasing MonetDBLite for Python. Using MonetDBLite for Python, you can easily use MonetDB's powerful features from within your Python client without having to run and maintain a separate database server. As both MonetDB and Python run within the same process, data transfer between the two is extremely efficient, as no actual transfer takes place.

MonetDB goes headless

In the beginning of MonetDB (in the 90's) there were BATs, Binary Association Tables, which is considered the minimal relationship to be maintained in an RDBMS [1]. A BAT consisted of BUNs, Binary UNits, which in turn consisted of a HEAD and a TAIL value. All head and tail values of a BAT were of the same type, but the head and tail types were independent of each other. There were (and still are) a whole bunch of built-in types from which to choose, and types could (and still can) be added in extension code.
