What this paper does with SQLancer

One citation, introducing NoREC as a method for detecting optimization bugs in query engines, in a review of how relational DBMS reliability has been studied. The first large-scale empirical study of defects in vector database management systems, which the authors argue traditional database reliability models do not fit because data representation, query mechanisms and architecture all differ. They manually analysed 1,671 bug-fix pull requests across 15 open-source vector databases and built a taxonomy by symptom, root cause and fix strategy, reporting 31 recurring fault patterns.
