Remote Execution & Distributed Caching

Fish supports high-performance distributed caching and remote execution protocols.

Remote Execution API (REAPI v2)

Fish ships a Remote Execution API v2-compatible data model (ReapiDigest, ReapiDirectory, ReapiFileNode in crates/fish-remote-cache/src/reapi.rs) transported over HTTP/JSON — not gRPC. The workspace has no protobuf/gRPC dependencies; see go-services.md for the planned gRPC transport.

fish build --remote-workers 10.0.0.1:8980,10.0.0.2:8980

P2P Swarm Caching

Enables zero-configuration peer-to-peer artifact sharing over local area networks:

fish build --swarm

Cloud CAS Backends

Configure S3, GCS, Azure Blob, or Redis storage in fish.toml:

[cache]
enabled = true
remote_url = "s3://my-fish-cache-bucket"
compression = "zstd"
