Tim, In fact, MonetDB is kind of unique in the sense that it *never* does tuple reconstruction. The low-level APIs tgat receive the result if a query get back tables, which are still represented as BATs (arrays in which values belonging to the same tuple are located at the same position). Othe

Hi Tim, thanks for you interest in MonetDB. In general, the recommend way to use MonetDB is via SQL, i.e., staying in the standard multi-column relational world. Then, MonetDB (in particular its SQL front-end) will automatically and transparently take care of using the most efficient internal al

2011-07-04 Thread Tim Speier
Dear all, I'm trying to understand the tuple reconstruction algorithm in MonetDB. Maybe someone can give me a short overview to understand it or the place in documentation where I can do some research. As far as I understood, the BAT consists of object-ids and values. Is the object-identifier the
