“Born from the ashes of Stadia, this repository contains tools for syncing and streaming files from Windows to Windows or Linux.”
Stadia developers had to push dozens of GBs of game builds over home connections with scp, which has no delta mode. Google built cdc_rsync, whose diffing runs up to 30x faster than rsync’s, 1500 MB/s against 50 MB/s. A 40-45 GB build synced in 75 seconds instead of 210. Stadia is dead, and the build tooling for it is the part worth keeping.
