Appenders allow users to append configuration that is already built with the help of either templates or builders. Appenders can be configured to be applied only when a required condition is matched. The kind of configuration that is applied is specific to each appender.
The config appender can apply a config on top of the config that was generated by templates or builders. The config is applied whenever a provided condition is matched. It is always applied if there is no condition provided.
