+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+Kafka: Gerrit event producer for Apache Kafka
+=======================
+
+* Author: GerritForge
+* Repository: https://gerrit.googlesource.com/plugins/kafka
+* CI/Release: https://gerrit-ci.gerritforge.com/search/?q=kafka
+
+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`
+* `Buck`
+
+Build
+---------------------
+
+Clone or link this plugin to the plugins directory of Gerrit's source
+tree, and issue the command:
+
+
+    buck build plugins/kafka
+
+The output is created in
+
+    buck-out/gen/plugins/kafka/kafka.jar
+
+Minimum Configuration
+---------------------
+Assuming a running Kafka broker on the same Gerrit host, add the following
+settings to gerrit.config:
+
+```
+  [plugin "kafka"]
+    server = localhost:9092
+    topic = gerrit-events
+```

+Build
+=====
+
+This plugin is built with Buck.
+
+Build in Gerrit tree
+--------------------
+
+Clone or link this plugin to the plugins directory of Gerrit's source
+tree, and issue the command:
+
+```
+  buck build plugins/kafka-events
+```
+
+The output is created in
+
+```
+  buck-out/gen/plugins/kafka-events/kafka-events.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+  ./tools/eclipse/project.py
+```
+
+How to build the Gerrit Plugin API is described in the [Gerrit
+documentation](../../../Documentation/dev-buck.html#_extension_and_plugin_api_jar_files).

+Apache Kafka Configuration
+======================
+
+Some parameters can be configured using Gerrit config file.
+
+Sample config
+---------------------
+
+```
+[plugin "kafka-events"]
+        bootstrapServers = localhost:9092
+```
+
+All the Apache Kafka properties configuration needs to
+be defined in gerrit.config using a lower camel-case notation.
+
+Example: bootstrapServers correspond to the Apache Kafka property
+bootstrap.servers.
+
+See [Apache Kafka Producer Config](http://kafka.apache.org/documentation.html#producerconfigs)
+for a full list of available settings and the values allowed.
+
+Default Values
+-----------------
+
+|name                 | value
+|:--------------------|:------------------
+| acks                | all
+| retries             | 0
+| batchSize           | 16384
