Some facts. I'm not sure how is that helpful in real life or how important but I'm adding them just for information: * SQLite itself has configurable cache and some other caching options: a) http://www.sqlite.org/pragma.html#pragma_cache_size http://www.sqlite.org/pragma.html#pragma_cache_size b) https://www.sqlite.org/sharedcache.html https://www.sqlite.org/sharedcache.html * Node.js has SQLite library with caching option (matter of single line). https://github.com/mapbox/node-sqlite3/wiki/Caching https://github.com/mapbox/node-sqlite3/wiki/Caching . It might be possible that other languages has something similar as well. P.S. Here is one of sites running on SQLite http://skaityta.lt/ http://skaityta.lt/ with some caching.
