Hi, When it comes to maintenance outage, flume needs to be shutdown and offline for a while. We want to make sure flume's WAL is completed before we shut down the process. Is there anyway or any metrics exposed can indicate WAL is fully processed so that it's safe to bring it down gracefully?
Of coz, the assumption here is that, the source of flume is not writing any new data, flume only has a certain size backlog needs to be cleaned up. -- All the best, Shengjie Min
