Cloudflare Tests Cache Transcoding Prototype

Cloudflare described a prototype called Cache Transcoding that compresses eligible cache content, mainly uncompressed text like HTML, JSON, CSS, and JavaScript, using Zstandard before storing it on disk. The hyperscaler estimates the approach could provide petabytes of additional effective cache capacity. Compression reduced the size of eligible content by about 2.8 times, allowing existing servers to store more data and reducing inter-datacenter transfers.
