The document discusses the Fluentd logging system. It includes an explanation of how Fluentd buffers and queues log data before outputting it. The emit method is used to add log data to a chunk, and if the chunk limit is reached a new chunk is created and added to the queue. Once data is in the queue it can be output by the configured plugin.Read less
