Has there been any High Scalability articles on their infrastructure? We have a similar need: storing a large volume of text-based content over a period of time, with versioning as well. On top of it we have various metadata. We're currently storing everything in MySQL -- a lightweight metadata row and a separate table for the large (~400KB on average) BLOB fields in a compressed table.We're looking at ways to improve our architecture: simply bigger+faster hardware? Riak with LevelDB as a backend? Filesystem storing with database for the metadata? We even considered using version control such as git or hg but that proved to be far too slow for reads compared to a PK database row lookup.Any HN'ers have suggestions?
