File systems unfit as distributed storage backends: lessons from 10 years of Ceph evolution Aghayev et al., In this case, the assumption that a distributed storage backend should clearly be layered on top of a local file system. What is a distributed storage backend? SOSP’19. This is not surprising in hindsight.

This reduction in latency ensures that applications and websites provide a more rapid and responsive user experience. An unoptimized indexing strategy can impede data insertion and retrieval operations. One effective strategy is query rewriting, where you restructure your SQL queries to be more efficient.
