DiceDB
DiceDB is a redis-compliant, in-memory, real-time, and reactive database optimized for modern hardware and for building and scaling truly real-time applications.
We are looking for Early Design Partners, so, if you want to evaluate DiceDB, block our calendar. always up for a chat.
Note: DiceDB is still in development and it supports a subset of Redis commands. So, please do not use it in production. But, feel free to go through the open issues and contribute to help us speed up the development.
Want to contribute?
We have multiple repositories where you can contribute. So, as per your interest, you can pick one and build a deeper understanding of the project on the go.
- dicedb/dice for core database features and engine / Stack - Go
- dicedb/dicedb-cli command line interface for DiceDB / Stack - Go
- dicedb/playground-mono backend APIs for DiceDB playground / Stack - Go
- dicedb/alloy frontend and marketplace for DiceDB playground / Stack - NextJS
How is it different from Redis?
Although DiceDB is a drop-in replacement of Redis, which means almost no learning curve and switching does not require any code change, it still differs in two key aspects and they are
- DiceDB is multithreaded and follows shared-nothing architecture.
- DiceDB supports
.WATCH
commands likeGET.WATCH
,ZRANGE.WATCH
, etc. that lets clients listen to data changes and get the result set in real-time whenever something changes.
.WATCH
commands are pretty handy when it comes to building truly real-time applications like Leaderboard.
Get started
Setting up DiceDB with Docker
The easiest way to get started with DiceDB is using Docker by running the following command.
docker run -p 7379:7379 dicedb/dicedb --enable-multithreading --enable-watch
The above command will start the DiceDB server running locally on the port 7379
and you can connect
to it using DiceDB CLI and SDKs.
Setting up CLI
The best way to connect to DiceDB is using DiceDB CLI and you can install it by running the following command
sudo su
curl -sL https://raw.githubusercontent.com/DiceDB/dicedb-cli/refs/heads/master/install.sh | sh
If you are working on unsupported OS (as per above script), you can always follow the installation instructions mentioned in the dicedb/cli repository.
For development and contributions
To run DiceDB for local development or running from source, you will need
- Golang
- Any of the below supported platform environments:
- Linux based environment
- OSX (Darwin) based environment
- WSL under Windows
git clone https://github.com/dicedb/dice
cd dice
go run main.go --enable-multithreading --enable-watch
You can skip passing the two flags if you are not working with multi-threading or .WATCH
features.
- Install GoLangCI
sudo su
curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s -- -b /bin v1.60.1
Live Development Server
DiceDB provides a hot-reloading development environment, which allows you to instantly view your code changes in a live server. This functionality is supported by Air
To Install Air on your system you have the following options.
- If you're on go 1.22+
go install github.com/air-verse/air@latest
- Install the Air binary
# binary will be installed at $(go env GOPATH)/bin/air
curl -sSfL https://raw.githubusercontent.com/air-verse/air/master/install.sh | sh -s -- -b $(go env GOPATH)/bin
Once air
is installed you can verify the installation using the command air -v
To run the live DiceDB server for local development:
git clone https://github.com/dicedb/dice
cd dice
air
Local Setup with Custom Config
By default, DiceDB will look for the configuration file at /etc/dice/config.toml
. (Linux, Darwin, and WSL)
# set up configuration file # (optional but recommended)
sudo mkdir -p /etc/dice
sudo chown root:$USER /etc/dice
sudo chmod 775 /etc/dice # or 777 if you are the only user
git clone https://github.com/DiceDB/dice.git
cd dice
go run main.go -init-config
For Windows Users:
If you're using Windows, it is recommended to use Windows Subsystem for Linux (WSL) or WSL 2 to run the above commands seamlessly in a Linux-like environment.
Alternatively, you can:
Create a directory at C:\ProgramData\dice
and run the following command to generate the configuration file:
go run main.go -init-config
For a smoother experience, we highly recommend using WSL.
Additional Configuration Options:
If you'd like to use a different location, you can specify a custom configuration file path with the -c flag
:
go run main.go -c /path/to/config.toml
If you'd like to output the configuration file to a specific location, you can specify a custom output path with the -o flag
:
go run main.go -o /path/of/output/dir
Setting up CLI
The best way to connect to DiceDB is using DiceDB CLI and you can install it by running the following command
sudo su
curl -sL https://raw.githubusercontent.com/DiceDB/dicedb-cli/refs/heads/master/install.sh | sh
If you are working on unsupported OS (as per above script), you can always follow the installation instructions mentioned in the dicedb/cli repository.
Running Tests
Unit tests and integration tests are essential for ensuring correctness and in the case of DiceDB, both types of tests are available to validate its functionality.
For unit testing, you can execute individual unit tests by specifying the name of the test function using the TEST_FUNC
environment variable and running the make unittest-one
command. Alternatively, running make unittest
will execute all unit tests.
Executing one unit test
TEST_FUNC=<name of the test function> make unittest-one
TEST_FUNC=TestByteList make unittest-one
Running all unit tests
make unittest
Integration tests, on the other hand, involve starting up the DiceDB server and running a series of commands to verify the expected end state and output. To execute a single integration test, you can set the TEST_FUNC
environment variable to the name of the test function and run make test-one
. Running make test
will execute all integration tests.
Executing a single integration test
TEST_FUNC=<name of the test function> make test-one
TEST_FUNC=TestSet make test-one
Running all integration tests
make test
Work to add more tests in DiceDB is in progress, and we will soon port the test Redis suite to this codebase to ensure full compatibility.
Running Benchmark
go test -test.bench <pattern>
go test -test.bench BenchmarkListRedis -benchmem
Getting Started
To get started with building and contributing to DiceDB, please refer to the issues created in this repository.
Docs
We use Astro framework to power the dicedb.io website and Starlight to power the docs. Once you have NodeJS installed, fire the following commands to get your local version of dicedb.io running.
cd docs
npm install
npm run dev
Once the server starts, visit http://localhost:4321/ in your favourite browser. This runs with a hot reload which means any changes you make in the website and the documentation can be instantly viewed on the browser.
To build and deploy
cd docs
npm run build
Docs directory structure
-
docs/src/content/docs/commands
is where all the commands are documented -
docs/src/content/docs/tutorials
is where all the tutorials are documented
The story
DiceDB started as a re-implementation of Redis in Golang and the idea was to - build a DB from scratch and understand the micro-nuances that come with its implementation. The database does not aim to replace Redis, instead, it will fit in and optimize itself for multicore computations running on a single-threaded event loop.
