Replit· 6 MarUsing Tvix Store to Reduce Nix Storage Costs by 90%
Replit reduced Nix storage costs by 90% using Tvix Store.
Replit implemented Tvix Store, a content-addressed Nix store implementation, to compress its 6TB cache of Nix store paths into 1.2TB, reducing storage costs for the persistent disk cache by 90%.
The implementation uses a FUSE filesystem to expose the compressed store while maintaining backward compatibility for older packages.
