SQLite compressed text-history prototypes

Simon Willison developed SQLite compressed text-history prototypes to efficiently store revision histories in relational databases. The prototypes, `WholeBlobHistoryStore` and `ChunkedHistoryStore`, use zlib or zstd compression on JSON arrays of text and timestamps. They aim to reduce storage overhead compared to storing each full revision separately. A simulation showed 1,000 revisions, totaling 20.4 MB of raw text, compressed to 80.3 KB using Zstandard. This approach addresses the challenge of scaling revision history storage for frequently edited documents.

This research offers developers a more efficient method for storing document revision histories in SQLite, significantly reducing storage requirements.
