OpenSearch Benchmark is the macrobenchmarking framework for OpenSearch.
If you are looking to performance test OpenSearch, then OpenSearch Benchmark is for you. It can help you with the following tasks:
- Running performance benchmarks and recording results
- Setting up and tearing down OpenSearch clusters for benchmarking
- Managing benchmark data and specifications across OpenSearch versions
- Discovering performance problems by attaching so-called telemetry devices
- Comparing performance results
- Creating customized workloads
We have also put considerable effort into OpenSearch Benchmark to ensure that benchmarking data are reproducible.
Documentation for OpenSearch Benchmark is available online.
OpenSearch Benchmark is developed for Unix and is actively tested on Linux, Ubuntu, and MacOS. OpenSearch Benchmark supports benchmarking OpenSearch clusters running on Windows but OpenSearch Benchmark itself needs to be installed on machines running Unix.
Note: If you actively develop on OpenSearch, we recommend that you install OpenSearch Benchmark in development mode instead as OpenSearch is fast moving and OpenSearch 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 and that the corresponding Java executable in $JAVA_HOME/bin is picked up via your PATH environment variable. Then run the following command, optionally prefixed by sudo if necessary:
python3 -m pip 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 one of OpenSearch Benchmark's official workloads - 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:
