Fileupload Gunner Project | New

upload: timeout_seconds: 3600 # 1 hour max for 10GB files Never reuse temp directories across projects. The project new command automatically generates a UUID-based temp path, but verify with:

gunner validate --config ./config/upload.yaml 1. Automatic Chunk Reassembly One standout feature of the fileupload gunner project new architecture is its intelligent chunk reassembly. When a client uploads a file in chunks, Gunner temporarily stores each chunk in Redis with a TTL (time-to-live). Once all chunks are received, a background worker reassembles them in the correct order using a deterministic chunking algorithm.

npx gunner-cli project new --type fileupload --name my-upload-service Or if using the Go-based Gunner: When a client uploads a file in chunks,
