plugin.@PLUGIN@.groupId : Kafka consumer group for receiving messages. Default: Gerrit instance-id
plugin.@PLUGIN@.pollingIntervalMs : Polling interval in msec for receiving messages from Kafka topic subscription. Default: 1000
plugin.@PLUGIN@.numberOfSubscribers : The number of consumers that are expected to be executed. This number will be used to allocate a thread pool of a suitable size. Default to 6. This is to allow enough resources to consume all relevant gerrit topics in a multi-site deployment: batchIndexEventTopic streamEventTopic, gerritTopic, projectListEventTopic, cacheEventTopic, indexEventTopic
plugin.@PLUGIN@.sendAsync : Send messages to Kafka asynchronously, detaching the calling process from the acknowledge of the message being sent. Default: true
plugin.@PLUGIN@.topic : Send all gerrit stream events to this topic (when sendStreamEvents is set to true). Default: gerrit
plugin.@PLUGIN@.sendStreamEvents : Whether to send stream events to the topic topic. Default: false
The @PLUGIN@ plugin provides an init step that helps to set up the configuration.
