Benchmark configuration

Benchmarks require a dedicated configuration file pointing to test databases. This isolates benchmark runs from production data.

Configuration file

The benchmark uses a standard Meta config YAML with test-specific values. A reference config is provided at oc_meta/run/benchmark/benchmark_config.yaml.

Required settings

# Test triplestore endpoints
triplestore_url: http://127.0.0.1:8805/sparql
provenance_triplestore_url: http://127.0.0.1:8806/sparql

# Benchmark directories
input_csv_dir: oc_meta/run/benchmark/input
base_output_dir: oc_meta/run/benchmark/output
output_rdf_dir: oc_meta/run/benchmark/output/

# Test Redis (separate from production)
redis_host: localhost
redis_port: 6381
redis_db: 10
cache_db: 11

Test databases

Start the test databases before running benchmarks:

./test/start-test-databases.sh

This starts:

• Virtuoso (data): port 8805
• Virtuoso (provenance): port 8806
• Redis: port 6381

Cleanup

By default, the benchmark resets all test databases after each run:

• Virtuoso: RDF_GLOBAL_RESET() via Docker exec
• Redis: FLUSHDB on counter and cache databases
• Output files: deleted

Use --no-cleanup to preserve data for inspection.
