	Graph service - Java backend
	============================

	Server side Java RPC API.

	Build
	-----

	```bash
	$ mvn compile assembly:single
	```

	Start RPC API
	-------------

	```bash
	$ java -cp target/swh-graph-*.jar \
	org.softwareheritage.graph.server.App \
	<compressed_graph_path>
	```

	Default port is 5009 (use the `--port` option to change port number). If you
	need timings metadata send back to the client in addition to the result, use the
	`--timings` flag.

	Tests
	-----

	Unit tests rely on test data that are already available in the Git repository
	(under `src/swh/graph/tests/dataset/`). You generally only need to run them
	using Maven:

	```bash
	$ mvn test
	```

	In case you want to regenerate the test data:

	```bash
	# Graph compression
	$ cd src/swh/graph/tests/dataset
	$ ./generate_graph.sh
	$ cd ../../../..

	$ mvn compile assembly:single
	# Dump mapping files
	$ java -cp target/swh-graph-*.jar \
	org.softwareheritage.graph.maps.NodeMapBuilder \
	src/swh/graph/tests/dataset/example.nodes.csv.gz \
	src/swh/graph/tests/dataset/output/example
	```
