Send/receive Event object instead of EventMessage

Event object contains instance id populated by Gerrit Core. Workaround
with EventMessage using sourceInstanceId field to recognise the event
source node is not needed anymore. Use Event object instead of
EventMessage.

Kafka: Gerrit event producer for Apache Kafka

Build Status

Synopsis

This plugins allows to define a distributed stream of events published by Gerrit.

Events can be anything, from the traditional stream events to the Gerrit metrics.

This plugin requires Gerrit 2.13 or laster.

Environments

  • linux
  • java-1.8
  • Bazel

Build

Kafka plugin can be build as a regular ‘in-tree’ plugin. That means that is required to clone a Gerrit source tree first and then to have the Kafka plugin source directory into the /plugins path. Additionally, the plugins/external_plugin_deps.bzl file needs to be updated to match the Kafka plugin one.

git clone --recursive https://gerrit.googlesource.com/gerrit
git clone https://gerrit.googlesource.com/plugins/events-kafka gerrit/plugins/events-kafka
cd gerrit
rm plugins/external_plugin_deps.bzl
ln -s ./events-kafka/external_plugin_deps.bzl plugins/.

To build the events-kafka plugins, issue the command from the Gerrit source path:

bazel build plugins/events-kafka

The output is created in

bazel-genfiles/plugins/events-kafka/events-kafka.jar

Minimum Configuration

Assuming a running Kafka broker on the same Gerrit host, add the following settings to gerrit.config:

  [plugin "events-kafka"]
    bootstrapServers = localhost:9092
