Developing RedisTimeSeries ¶
Developing RedisTimeSeries involves setting up the development environment (which can be either Linux-based or macOS-based), building RedisTimeSeries, running tests and benchmarks, and debuugging both the RedisTimeSeries module and its tests.
Cloning the git repository ¶
By invoking the following command, RedisTimeSeries module and its submodules are cloned:
git clone --recursive https://github.com/RedisTimeSeries/RedisTimeSeries.git
Working in an isolated environment ¶
There are several reasons to develop in an isolated environment, like keeping your workstation clean, and developing for a different Linux distribution. The most general option for an isolated environment is a virtual machine (it's very easy to set one up using Vagrant ). Docker is even a more agile solution, as it offers an almost instant solution:
ts=$(docker run -d -it -v $PWD:/build debian:buster bash) docker exec -it $ts bash
Then, from whithin the container,
and go on as usual.
In this mode, all installations remain in the scope of the Docker container.
Upon exiting the container, you can either re-invoke the container with the above
or commit the state of the container to an image and re-invoke it on a later stage:
docker commit $ts ts1 docker stop $ts ts=$(docker run -d -it -v $PWD:/build ts1 bash) docker exec -it $ts bash
Installing prerequisites ¶
To build and test RedisTimeSeries one needs to install serveral packages, depending on the underlying OS. Currently, we support the Ubuntu/Debian, CentOS, Fedora, and macOS.
If you have
installed, you can execute
cd RedisTimeSeries git submodule update --init --recursive make setup
Alternatively, just invoke the following:
cd RedisTimeSeries git submodule update --init --recursive ./deps/readies/bin/getpy3 ./system-setup.py
will install various packages on your system
using the native package manager and pip. This requires root permissions (i.e. sudo) on Linux.
If you prefer to avoid that, you can:
- Review system-setup.py and install packages manually,
- Use an isolated environment like explained above,
- Utilize a Python virtual environment, as Python installations known to be sensitive when not used in isolation.
Next, execute the following, to complete dependency acquisition:
Installing Redis ¶
As a rule of thumb, you're better off running the latest Redis version.
If your OS has a Redis 5.x package, you can install it using the OS package manager.
Otherwise, you can invoke
Getting help ¶

Building from source ¶

will invoke both CMake and the subsequent make command that's required to complete the build.
to remove built artifacts.
make clean ALL=1
will remove the entire
Diagnosing CMake ¶
To get a glimpse into CMake decesion process, add
to the build command.
CMake stores its intermediate files in
Afterwards, one can use:
cd build make -n
cd build make V=1
to further diagnose the build process.
Running Redis with RedisTimeSeries ¶
The following will run
and load RedisTimeSeries module.
You can open
in another terminal to interact with it.
Running tests ¶
The module includes a basic set of unit tests and integration tests:
* C unit tests, located in
, run by
* Python integration tests (enabled by RLTest), located in
, run by
One can run all tests by invoking
make unittests test
A single test can be run using the
make test TEST=regex
To build for debugging (enabling symbolic information and disabling optimization), run
One can the use
make run DEBUG=1
In addition to the usual way to set breakpoints in
, it is possible to use the
macro to set a breakpoint inside RedisTimeSeries code. It will only have an effect when running under
Similarly, Python tests in a single-test mode, one can set a breakpoint by using the
function inside a test.
