Benchmark is the macrobenchmarking framework for OpenSearch
You want to benchmark OpenSearch? Then Benchmark is for you. It can help you with the following tasks:
- Setup and teardown of an OpenSearch cluster for benchmarking
- Management of benchmark data and specifications even across OpenSearch versions
- Running benchmarks and recording results
- Finding performance problems by attaching so-called telemetry devices
- Comparing performance results
We have also put considerable effort in Benchmark to ensure that benchmarking data are reproducible.
Benchmark is developed for Unix and is actively tested on Linux and MacOS. Benchmark supports benchmarking OpenSearch clusters running on Windows but Benchmark itself needs to be installed on machines running Unix.
Note: If you actively develop on OpenSearch, we recommend that you install Benchmark in development mode instead as OpenSearch is fast moving and Benchmark always adapts accordingly to the latest main version.
Install Python 3.8+ including pip3, git 1.9+ and an appropriate JDK to run OpenSearch Be sure that JAVA_HOME points to that JDK. Then run the following command, optionally prefixed by sudo if necessary:
pip3 install opensearch-benchmark
If you have any trouble or need more detailed instructions, please look in the detailed installation guide.
Now we're ready to run our first test execution:
opensearch-benchmark execute_test --distribution-version=1.0.0 --workload=geonames --test-mode
This will download OpenSearch 1.0.0 and run Benchmark's default workload - the geonames workload - against it.
Note that this uses the --test-mode argument to only run a single instance of each operation in order to reduce the time needed for a test execution. This argument is used as a sanity check and should be removed in an actual benchmarking scenario.
After the test execution, a summary report is written to the command line:
