Seminar "Query Compilation on Modern Hardware"


March 22, 2021 Web page setup.


Query compilation is a processing technique that achieves very high processing speeds by generating query-specific machine code. In the past, promising techniques were discussed, e.g. the use of templates, generation of C++ code, or the use of low-level intermediate representations. In this seminar, we will look at some of the methods and discuss their advantages and disadvantages.

The seminar will be held in English. Interested students are invited to contact Jan Mühlig () with their three favorite topics until 08.04.2022.

More topics might follow.



The presentations will be held (probably in attendance) in two blocks.

The talks are scheduled for 20 minutes, each talk is followed by a discussion on the topic and the presentation.


The report should follow the ACM Proceedings Templates (LaTeX or Word) with a maximum of six pages (including references). Each student reviews two reports from other students.


Each participant will review two other participants' submissions using a provided conferencing system. The feedback is used to improve their report and is given before the presentation.
