The @PLUGIN@ plugin must be installed in both instances and the following fields should be specified in the corresponding Gerrit configuration file:
[plugin “@PLUGIN@”] : url = target_instance_url : user = username : password = password : sharedDirectory = /directory/accessible/from/both/instances
plugin.@PLUGIN@.url : Specify the URL for the secondary (target) instance.
plugin.@PLUGIN@.user : Username to connect to the secondary (target) instance.
plugin.@PLUGIN@.password : Password to connect to the secondary (target) instance. This value can also be defined in secure.config.
plugin.@PLUGIN@.sharedDirectory : Path to a directory accessible from both master instances.
@PLUGIN@ plugin uses REST API calls to keep the target instance in-sync. It is possible to customize the parameters of the underlying http client doing these calls by specifying the following fields:
@PLUGIN@.connectionTimeout : Maximum interval of time in milliseconds the plugin waits for a connection to the target instance. When not specified, the default value is set to 5000ms.
@PLUGIN@.socketTimeout : Maximum interval of time in milliseconds the plugin waits for a response from the target instance once the connection has been established. When not specified, the default value is set to 5000ms.
@PLUGIN@.maxTries : Maximum number of times the plugin should attempt when calling a REST API in the target instance. Setting this value to 0 will disable retries. When not specified, the default value is 5. After this number of failed tries, an error is logged.
@PLUGIN@.retryInterval : The interval of time in milliseconds between the subsequent auto-retries. When not specified, the default value is set to 1000ms.
@PLUGIN@.indexThreadPoolSize : Maximum number of threads used to send index events to the target instance. Defaults to 1.
@PLUGIN@.eventThreadPoolSize : Maximum number of threads used to send stream events to the target instance. Defaults to 1.
@PLUGIN@.cacheThreadPoolSize : Maximum number of threads used to send cache evictions to the target instance. Defaults to 1.
