rust-dataflow-git

Rust Dataflow (Git-based)

Same three-node pipeline as rust-dataflow, but node source code is fetched from a Git repository with version pinning via tags.

Architecture

timer (10ms) --> rust-node --> random --> rust-status-node --> status --> rust-sink
                               timer (100ms) -->

How Git Loading Works

Instead of referencing local paths, each node specifies a Git URL and tag:

- id: rust-node
  git: https://github.com/dora-rs/dora.git
  tag: v0.1.0
  build: cargo build -p rust-dataflow-example-node
  path: target/debug/rust-dataflow-example-node

Dora clones the repository at the pinned tag, runs the build: command inside the clone, then executes the built binary. This enables:

• Version pinning: tag: ensures reproducible builds
• Remote nodes: pull node code from any Git repository
• Independent versioning: each node can use a different tag or repo

Run

cargo run --example rust-dataflow-git

Or directly:

dora build dataflow.yml
dora run dataflow.yml

What This Demonstrates

Feature	Where
git: for remote source fetching	YAML (all nodes)
tag: for version pinning	YAML (all nodes)
build: for post-clone compilation	YAML (all nodes)
Same topology, different deployment model	vs rust-dataflow
