Tidy Tuples and Flying Start: fast compilation and fast execution of relational queries in Umbra

Timo Kersten, Viktor Leis, Thomas Neumann
2021 The VLDB journal  
We implemented these optimizations in our database system Umbra to show that it is possible to unite fast compilation and fast execution. Indeed, Umbra achieves unprecedentedly low query latencies.  ...  In this paper, we examine all stages of compiling query execution engines and show how to reduce compilation overhead.  ...  Summary This paper presented the Tidy Tuples architecture, the Umbra IR program representation, and the Flying Start compiler backend to minimize query latency in compiling relational database systems.  ...
