Cloudflare Tests Cache Transcoding to Reduce Storage Requirements

A surprising amount of cacheable text still arrives uncompressed: Cloudflare measured about 71% of it. Its cache transcoding prototype compresses those objects once on the way into cache using Zstandard and Pingora, shrinking eligible content roughly 2.8x and freeing what it estimates as petabytes of capacity. Objects under 4 KiB are skipped, costing about 1% of eligible data. Still a prototype, but worth borrowing.
