Benchmarking

Setting up a benchmark involves three steps:

  • Creating a benchmark configuration
  • Creating a benchmark execution from a configuration
  • Actually running the execution

Creating a benchmark configuration

This step requires a SPARQL endpoint with a benchmark dataset to be accessible. The essential arguments are the URL to the endpoint and a label for the dataset hosted in the endpoint.

A certain URL of a SPARQL endpoint may host many RDF graphs / datasets (= specific sets of triples or quads) as time passes by. Usually, these datasets do not have agreed upon labels or identifiers; but having a rather generic label - such as ‘dbpedia’ (whic specific subset of the hundreds of DBpedia files does this involve?) - is better than having no indication of the dataset at all. This is particularly true if benchmarking is performed locally using localhost URLs.

Hence, an endpoint URL and a dataset label have to be provided to the benchmark create command:

lsq benchmark create --endpoint http://localhost:8890/sparql --dataset mydataset -o

# Short version:
# lsq benchmark create -e http://localhost:8890/sparql -d mydataset -o

The result of the invocation is a turtle document with several paramaters which can now be adjusted:

:warning: You should NEVER change a configuration once you executed a run from it. Conversely: All runs created from a specific configuration should use the same parameters in order to facilitate comparability.

        dct:identifier                "xc-mydataset_2020-08-12" .

The next step is to prepare a benchmark run - this essentially just takes your config and associates it with a timestamp:

lsq benchmark prepare -c conf.ttl
# Output is the path to the generated run file e.g. /home/foo/conf.run.ttl

The final step is to actually start the benchmark

lsq benchmark run -c conf.run.ttl log.trig foo/*.trig
