Databases have achieved orders-of-magnitude performance improvements by changing the layout of stored data - for instance, by arranging data in columns or compressing it before storage. These improvements have been implemented in monolithic new engines, however, making it difficult to experiment with feature combinations or extensions. The authors present Anvil, a modular and extensible toolkit for building database back ends. Anvil's storage modules, called dTables, have much finer granularity than prior work. For example, some dTables specialize in writing data, while others provide optimized read-only formats. This specialization makes both kinds of dTable simple to write and understand.
