Abstract
Database query processing and optimization are critical components of modern database management systems (DBMS) that efficiently process user queries. In big data application scenarios, the movement of large volumes of data influences performance, power efficiency, and reliability, which are the three essential aspects of a computing system. Large-scale data centers require an exceptionally efficient server and storage infrastructure. The systems currently employed for managing and processing big data are increasingly showing inefficiency, both in terms of energy usage and scalability, primarily due to the constraints imposed by existing CPU architectures. A significant challenge in Database Management Systems (DBMS) is the growing disparity between the speeds of processors and memory access, which results in notable performance bottlenecks. This paper presents a comprehensive survey of reconfigurable acceleration in database systems, offering a structured taxonomy that categorizes existing work based on query types, integration models, and hardware/software co-design strategies. We examine key acceleration techniques across relational operators, indexing, join algorithms, and compression, highlighting their trade-offs in performance, scalability, and adaptability. Furthermore, we identify current limitations in programmability, data movement, and workload variability, and outline open research challenges including dynamic reconfiguration, hybrid architectures, and compiler support. This taxonomy-driven perspective aims to guide both researchers and practitioners in navigating the design space and pushing the boundaries of FPGA-accelerated data processing.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
