SQLite compressed text-history prototypes
Compressed JSON arrays reduce 20MB of SQLite revision history to 80KB
“1,000 simulated revisions to a document resulted in 20.4 MB of raw revision text that compressed to 80.3 KB as Zstandard-compressed JSON array.”
Simon Willison prototyped a SQLite revision-history scheme using zstd-compressed JSON arrays, achieving 250x compression on 1,000 document revisions. Notably, he used GPT voice mode to brainstorm the idea then prompted GPT-5.6 Sol Pro to build the prototype over 38 minutes. The engineering result is solid but the AI-conference signal is thin — this is a developer workflow anecdote, not a major industry announcement.
