redis-benchmarks-specification 0.1.48

The Redis benchmarks specification describes the cross-language/tools requirements and expectations to foster performance and observability standards around redis related technologies. Members from both industry and academia, including organizations and individuals are encouraged to contribute.

Installation

To have access to the latest SPEC and Tooling impletamtion you only need to install one python package.

Installation is done using pip, the package installer for Python, in the following manner:

python3 -m pip install redis-benchmarks-specification --ignore-installed PyYAML

Benchmark specifications goal

The Redis benchmarks specification describes the cross-language/tools requirements and expectations to foster performance and observability standards around redis related technologies.

Members from both industry and academia, including organizations and individuals are encouraged to contribute.

Currently, the following members actively support this project:

• Redis Ltd. via the Redis Performance Group: providing steady-stable infrastructure platform to run the benchmark suite. Supporting the active development of this project within the company.

Scope

This repo aims to provide Redis related benchmark standards and methodologies for:

• Management of benchmark data and specifications across different setups

• Running benchmarks and recording results

• Exporting performance results in several formats (CSV, RedisTimeSeries, JSON)

• [SOON] Finding on-cpu, off-cpu, io, and threading performance problems by attaching profiling tools/probers ( perf (a.k.a. perf_events), bpf tooling, vtune )

• [SOON] Finding performance problems by attaching telemetry probes

Current supported benchmark tools:

• redis-benchmark
• memtier_benchmark
• [SOON]redis-benchmark-go

Installing Redis benchmarks specification implementations

The Redis benchmarks specification and implementations is developed for Unix and is actively tested on it.

Installation is done using pip, the package installer for Python, in the following manner:

python3 -m pip install redis-benchmarks-specification

In a very brief description, github.com/redis/redis upstream changes trigger an HTTP API call containing the relevant git information.

The HTTP request is then converted into an event ( tracked within redis ) that will trigger multiple build variants requests based upon the distinct platforms described in platforms.

As soon as a new build variant request is received, the build agent (redis-benchmarks-spec-builder) prepares the artifact(s) and proceeds into adding an artifact benchmark event so that the benchmark coordinator (redis-benchmarks-spec-sc-coordinator) can deploy/manage the required infrastructure and DB topologies, run the benchmark, and export the performance results.

Directory layout

Specifications

The following is a high level status report for currently available specs.

• redis_benchmarks_specification

  • test-suites: contains the benchmark suites definitions, specifying the target redis topology, the tested commands, the benchmark utility to use (the client), and if required the preloading dataset steps.

• redis_benchmarks_specification/setups

  • platforms: contains the standard platforms considered to provide steady stable results, and to represent common deployment targets.
  • topologies: contains the standard deployment topologies definition with the associated minimum specs to enable the topology definition.
  • builders: contains the build environment variations, that enable to build Redis with different compilers, compiler flags, libraries, etc...

Spec tool implementations

The following is a high level status report for currently available spec implementations.

• STATUS: Experimental redis-benchmarks-spec-api : contains the API that translates the POST HTTP request that was triggered by github.com/redis/redis upstream changes, and fetches the relevant git/source info and coverts it into an event ( tracked within redis ).

• STATUS: Experimental redis-benchmarks-spec-builder: contains the benchmark build agent utility that receives an event indicating a new build variant, generates the required redis binaries to test, and triggers the benchmark run on the listening agents.

• STATUS: Experimental redis-benchmarks-spec-sc-coordinator: contains the coordinator utility that listens for benchmark suite run requests and setups the required steps to spin the actual benchmark topologies and to trigger the actual benchmarks.

• STATUS: Experimental redis-benchmarks-spec-client-runner: contains the client utility that triggers the actual benchmarks against an endpoint provided. This tool is setup agnostic and expects the DB to be properly spinned beforehand.

Adding new test suites

TBD

Adding new topologies

TBD

Joining the performance initiative and adding a continuous benchmark platform

Joining the performance initiative

In order to join the performance initiative the only requirement is that you provide a steady-stable infrastructure platform to run the benchmark suites, and you reach out to one of the Redis Performance Initiative member via performance <at> redis <dot> com so that we can provide you with the required secrets to actively listen for benchmark events.

If you check the above "Architecture diagram", this means you only need to run the last moving part of the arch, meaning you will have one or more benchmark coordinator machines actively running benchmarks and pushing the results back to our datasink.

Adding a continuous benchmark platform

In order to be able to run the benchmarks on the platform you need pip installer for python3, and docker. Apart from it, we recommend you manage the redis-benchmarks-spec-sc-coordinator process(es) state via a process monitoring tool like supervisorctl, lauchd, daemon tools, or other.

For this example we relly uppon supervisorctl for process managing.

Installing package requirements

# install pip installer for python3
sudo apt install python3-pip -y
sudo pip3 install --upgrade pip

# install docker
sudo apt install docker.io -y

# install supervisord 
sudo apt install supervisor -y

# install benchmark specs
python3 -m pip install redis-benchmarks-specification --ignore-installed PyYAML

Testing out redis-benchmarks-spec-sc-coordinator

You should now be able to print the following installed benchmark runner help:

Note that the minimum arguments to run the benchmark coordinator are: --event_stream_host, --event_stream_port, --event_stream_pass, --event_stream_user You should use the provided credentials to be able to access the event streams. Apart from it, you will need to discuss with the Performance Group the unique platform name that will be used to showcase results, coordinate work, among other thigs.

If all runs accordingly you should see the following sample log when you run the tool with the credentials:

Adding redis-benchmarks-spec-sc-coordinator to supervisord

Let's add a supervisord entry as follow

vi /etc/supervisor/conf.d/redis-benchmarks-spec-sc-coordinator-1.conf

You can use the following template and update according to your credentials:

[supervisord]
loglevel = debug

[program:redis-benchmarks-spec-sc-coordinator]
