<p align="center"><img alt="Rally logo" src="https://raw.githubusercontent.com/elastic/rally/master/docs/rally-logo.svg" width="350px"></p> <h1 align="center">Rally</h1> Rally is the macrobenchmarking framework for Elasticsearch ## What is Rally? You want to benchmark Elasticsearch? Then Rally is for you. It can help you with the following tasks: * Setup and teardown of an Elasticsearch cluster for benchmarking * Management of benchmark data and specifications even across Elasticsearch 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 Rally to ensure that benchmarking data are reproducible. ## Quick Start Rally is developed for Unix and is actively tested on Linux and macOS. Rally supports [benchmarking Elasticsearch clusters running on Windows](http://esrally.readthedocs.io/en/stable/recipes.html#benchmarking-an-existing-cluster) but Rally itself needs to be installed on machines running Unix. ### Installing Rally **Note**: If you actively develop on Elasticsearch, we recommend that you [install Rally in development mode](https://esrally.readthedocs.io/en/latest/developing.html#installation-instructions-for-development) instead as Elasticsearch is fast moving and Rally always adapts accordingly to the latest main version. Install Python 3.10+ including `pip3`, git 1.9+ and an [appropriate JDK to run Elasticsearch](https://www.elastic.co/support/matrix#matrix_jvm). Be sure that `JAVA_HOME` points to that JDK. Then run the following command, optionally prefixed by `sudo` if necessary: pip3 install esrally If you have any trouble or need more detailed instructions, please look in the [detailed installation guide](https://esrally.readthedocs.io/en/latest/install.html). ## Run your first race Now we're ready to run our first race: esrally race --distribution-version=6.0.0 --track=geonames This will download Elasticsearch 6.0.0 and run Rally's default track - the [geonames track](https://github.com/elastic/rally-tracks/tree/master/geonames) - against it. After the race, a summary report is written to the command line: ------------------------------------------------------ _______ __ _____ / ____(_)___ ____ _/ / / ___/_________ ________ / /_ / / __ \/ __ `/ / \__ \/ ___/ __ \/ ___/ _ \ / __/ / / / / / /_/ / / ___/ / /__/ /_/ / / / __/ /_/ /_/_/ /_/\__,_/_/ /____/\___/\____/_/ \___/ ------------------------------------------------------ | Metric | Task | Value | Unit | |-------------------------------:|---------------------:|----------:|-------:| | Total indexing time | | 28.0997 | min | | Total merge time | | 6.84378 | min | | Total refresh time | | 3.06045 | min | | Total flush time | | 0.106517 | min | | Total merge throttle time | | 1.28193 | min | | Median CPU usage | | 471.6 | % | | Total Young Gen GC | | 16.237 | s | | Total Old Gen GC | | 1.796 | s | | Index size | | 2.60124 | GB | | Total written | | 11.8144 | GB | | Heap used for segments | | 14.7326 | MB | | Heap used for doc values | | 0.115917 | MB | | Heap used for terms | | 13.3203 | MB | | Heap used for norms | | 0.0734253 | MB | | Heap used for points | | 0.5793 | MB | | Heap used for stored fields | | 0.643608 | MB | | Segment count | | 97 | | | Min Throughput | index-append | 31925.2 | docs/s | | Median Throughput | index-append | 39137.5 | docs/s | | Max Throughput | index-append | 39633.6 | docs/s | | 50.0th percentile latency | index-append | 872.513 | ms | | 90.0th percentile latency | index-append | 1457.13 | ms | | 99.0th percentile latency | index-append | 1874.89 | ms | | 100th percentile latency | index-append | 2711.71 | ms | | 50.0th percentile service time | index-append | 872.513 | ms | | 90.0th percentile service time | index-append | 1457.13 | ms | | 99.0th percentile service time | index-append | 1874.89 | ms | | 100th percentile service time | index-append | 2711.71 | ms | | ... | ... | ... | ... | | ... | ... | ... | ... | | Min Throughput | painless_dynamic | 2.53292 | ops/s | | Median Throughput | painless_dynamic | 2.53813 | ops/s | | Max Throughput | painless_dynamic | 2.54401 | ops/s | | 50.0th percentile latency | painless_dynamic | 172208 | ms | | 90.0th percentile latency | painless_dynamic | 310401 | ms | | 99.0th percentile latency | painless_dynamic | 341341 | ms | | 99.9th percentile latency | painless_dynamic | 344404 | ms | | 100th percentile latency | painless_dynamic | 344754 | ms | | 50.0th percentile service time | painless_dynamic | 393.02 | ms | | 90.0th percentile service time | painless_dynamic | 407.579 | ms | | 99.0th percentile service time | painless_dynamic | 430.806 | ms | | 99.9th percentile service time | painless_dynamic | 457.352 | ms | | 100th percentile service time | painless_dynamic | 459.474 | ms | ---------------------------------- [INFO] SUCCESS (took 2634 seconds) ---------------------------------- ## Getting help * Quick help: `esrally --help` * Look in [Rally's user guide](https://esrally.readthedocs.io/) for more information * Ask questions about Rally in the [Rally Discuss forum](https://discuss.elastic.co/tags/c/elastic-stack/elasticsearch/rally). * File improvements or bug reports in our [Github repo](https://github.com/elastic/rally/issues). ## How to Contribute See all details in the [contributor guidelines](https://github.com/elastic/rally/blob/master/CONTRIBUTING.md). ## License This software is licensed under the Apache License, version 2 ("ALv2"), quoted below.
