Populating a Cache
------------------
A common use for Hydra is to pre-build and cache derivations which
take a long time to build. While it is possible to direcly access the
Hydra server's store over SSH, a more scalable option is to upload
built derivations to a remote store like an [S3-compatible object
store](https://nixos.org/manual/nix/stable/command-ref/new-cli/nix3-help-stores.html#s3-binary-cache-store). Setting
the `store_uri` parameter will cause Hydra to sign and upload
derivations as they are built:
```
store_uri = s3://cache-bucket-name?compression=zstd&parallel-compression=true&write-nar-listing=1&ls-compression=br&log-compression=br&secret-key=/path/to/cache/private/key
```
This example uses [Zstandard](https://github.com/facebook/zstd)
compression on derivations to reduce CPU usage on the server, but
[Brotli](https://brotli.org/) compression for derivation listings and
build logs because it has better browser support.
See [`nix help
stores`](https://nixos.org/manual/nix/stable/command-ref/new-cli/nix3-help-stores.html)
for a description of the store URI format.
