com.facebook.presto.jdbc.internal.netty.channel.ChannelFutureListener
Listens to the result of a {@link ChannelFuture}. The result of the asynchronous {@link Channel} I/O operation is notified once this listeneris added by calling {@link ChannelFuture#addListener(ChannelFutureListener)}.
Return the control to the caller quickly
{@link #operationComplete(ChannelFuture)} is directly called by an I/Othread. Therefore, performing a time consuming task or a blocking operation in the handler method can cause an unexpected pause during I/O. If you need to perform a blocking operation on I/O completion, try to execute the operation in a different thread using a thread pool.
