EvidentDB

EvidentDB is an event store for use in event sourcing. It is written in Kotlin and built atop pluggable backend storage systems, including Apache Kafka.

Status

EvidentDB is currently ALPHA quality software, and shouldn't be used in production, and so we're not yet publishing builds to artifact repositories. The API is mostly stable, but is still subject to change before we begin publishing our BETA and stable releases.

Building & Running the Server

EvidentDB uses Gradle as its build system, with some tasks orchestrated in the top-level Makefile.

make            # builds an application uber-JAR and native-executable binaries
make run        # Runs local kafka cluster, creates topics, and runs application
make perf       # Runs a quick and dirty perf test
make clean      # Cleans the build artifacts
make clean-all  # Cleans up all Kafka cluster and Streams state

Building & installing the Java/Kotlin client JAR

To use the EvidentDB JVM client, you'll need to build it and install to your local Maven repo:

make install-client

Then include the dependency in your build config.

Gradle:

implementation("com.evidentdb:client:0.1.0-alpha-SNAPSHOT")

Maven:

<dependency>
    <groupId>com.evidentdb</groupId>
    <artifactId>client</artifactId>
    <version>0.1.0-alpha-SNAPSHOT</version>
</dependency>

For more information on client usage, see the JVM client README.
