Injected State Example

This example demonstrates how to use injected state with a local state server.

Location

examples/injected_state/

Build

cd examples/injected_state
scarb build

Run (source build)

The script starts the state server and runs the pipeline:

./run.sh

Key details:

• state_server runs in the background.
• --injected_state examples/injected_state/injected_state.json is passed to dry run and sound run.

Run (CLI)

If you use the hdp binary, start the state server first:

cargo run --release --bin state_server

Then run the pipeline with --injected_state pointing to the JSON file.

If your state server runs on a non-default host/port, export INJECTED_STATE_BASE_URL before running the pipeline.
