I don't really understand your comment. Databases are generally I/O bound workloads, almost by definition of what they do. Regardless, data structures and algorithms are equally important in databases. B-Trees, linked-lists, buffers, LSM Trees, Bloom filters, caching strategies etc are all fundamental to databases. At any rate for a long time now the low hanging fruit of optimization has been throwing money and hardware at problems - NAND Flash, more cores, larger caches, tons of memory, edge networks etc. Those options are all still there.
