EventStoreDB is a new category of operational database that has evolved from the Event Sourcing community. Powered by the state-transition data model, events are stored with the context of why they have happened. Providing flexible, real-time data insights in the language your business understands.

Event Store Cloud is a fully managed cloud offering that's designed to make it easy for developers to build and run highly available and secure applications that incorporate EventStoreDB without having to worry about managing the underlying infrastructure. You can provision EventStoreDB clusters in AWS, Azure, and GCP, and connect these services securely to your own cloud resources.

For guidance on installation, development, deployment, and administration, see the User Documentation.

Follow the getting started guide.

Event Store can manage EventStoreDB for you, so you don't have to run your own clusters. See the online documentation: Getting started with Event Store Cloud.

This guide shows you how to get started with EventStoreDB by setting up an instance or cluster and configuring it. EventStoreDB supports two protocols: gRPC and TCP(legacy).

EventStoreDB supported gRPC clients

• Python: pyeventsourcing/esdbclient
• Node.js (javascript/typescript): EventStore/EventStore-Client-NodeJS
• Java: (EventStore/EventStoreDB-Client-Java
• .NET: EventStore/EventStore-Client-Dotnet
• Go: EventStore/EventStore-Client-Go

Development is done on the master branch. We attempt to do our best to ensure that the history remains clean and to do so, we generally ask contributors to squash their commits into a set or single logical commit.

If you want to switch to a particular release, you can check out the release branch for that particular release. For example:
git checkout release/oss-v22.10

EventStoreDB is written in a mixture of C# and JavaScript. It can run on Windows, Linux and macOS (using Docker) using the .NET Core runtime.

Prerequisites

• .NET Core SDK 8.0

Once you've installed the prerequisites for your system, you can launch a Release build of EventStore as follows:

dotnet build -c Release src

The build scripts: build.sh and build.ps1 are also available for Linux and Windows respectively to simplify the build process.

To start a single node, you can then run:

dotnet ./src/EventStore.ClusterNode/bin/x64/Release/net8.0/EventStore.ClusterNode.dll --dev --db ./tmp/data --index ./tmp/index --log ./tmp/log

You can launch the tests as follows:

dotnet test src/EventStore.sln

You can also build a Docker image by running the command:

docker build --tag myeventstore . \
--build-arg CONTAINER_RUNTIME={container-runtime}
--build-arg RUNTIME={runtime}

For instance:

docker build --tag myeventstore . \
--build-arg CONTAINER_RUNTIME=bookworm-slim \
--build-arg RUNTIME=linux-x64

Note: Because of the Docker issue, if you're building a Docker image on Windows, you may need to set the DOCKER_BUILDKIT=0 environment variable. For instance, running in PowerShell:

$env:DOCKER_BUILDKIT=0; docker build --tag myeventstore . `
--build-arg CONTAINER_RUNTIME=bookworm-slim `
--build-arg RUNTIME=linux-x64

Currently, we support the following configurations:

1. Bookworm slim:

• CONTAINER_RUNTIME=bookworm-slim
• RUNTIME=linux-x64

2. Jammy:

• CONTAINER_RUNTIME=Jammy
• RUNTIME=linux-x64

3. Alpine:

• CONTAINER_RUNTIME=alpine
• RUNTIME=linux-musl-x64

You can verify the built image by running:

docker run --rm myeventstore --insecure --what-if
