The perfect target candidate for zero cost abstractions is a data base api.
With databases as the bottleneck of web development it is not optimal to use such high level apis like SQL to optimize everything. We resort to ANALYZE and strange sql hacks to trick the query engine into performing the right algorithms when the api should explicitly let us choose to use or tweak both zero cost abstractions and/or a query planners.
