Crescando

Crescando is a scalable, distributed relational table implementation designed to perform large numbers of queries and updates with guaranteed access latency and data freshness. To this end, Crescando leverages a number of modern query processing techniques and hardware trends. Specifically, Crescando is based on parallel, collaborative scans in main memory and so-called “query-data” joins known from data-stream processing. While the approach is not always optimal for a given workload, it provides latency and freshness guarantees for all workloads. Thus, Crescando is particularly attractive if the workload is unknown, changing, or involves many different queries.
