What is TrogonDB

TrogonDB 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.

Building TrogonDB

TrogonDB 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

Running the tests

You can launch the tests as follows:

dotnet test src/EventStore.sln

Build TrogonDB Docker image

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. Noble:

• CONTAINER_RUNTIME=noble
• RUNTIME=linux-x64

You can verify the built image by running:

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