+/**
+ * <h1>Non-blocking streaming with netty</h1>
+ * This document describes the implementation details of streaming protocol. A listener for a streaming
+ * session listens on the same socket as internode messaging, and participates in the same handshake protocol
+ * That protocol is described in the package-level documentation for {@link org.apache.cassandra.net.async}, and
+ * thus not here.
+ *
+ * Streaming 2.0 was implemented as CASSANDRA-5286. Streaming 2.0 used (the equivalent of) a single thread and
+ * a single socket to transfer sstables sequentially to a peer (either as part of a repair, bootstrap, and so on).
+ * Part of the motivation for switching to netty and a non-blocking model as to enable file transfers to occur
+ * in parallel for a given session.
+ *
+ * Thus, a more detailed approach is required for stream session management.
+ *
+ * <h2>Session setup and management</h2>
+ *
+ * The full details of the session lifecycle are documented in {@link org.apache.cassandra.streaming.StreamSession}.
+ *
+ *
+ * <h2>File transfer</h2>
+ *
+ * When tranferring whole or subsections of an sstable, only the DATA component is shipped. To that end,
+ * there are three "modes" of an sstable transfer that need to be handled somewhat differently:
+ *
+ * 1) uncompressed sstable - data needs to be read into user space so it can be manipulated: checksum validation,
+ * apply stream compression (see next section), and/or TLS encryption.
+ *
+ * 2) compressed sstable, transferred with SSL/TLS - data needs to be read into user space as that is where the TLS encryption
+ * needs to happen. Netty does not allow the pretense of doing zero-copy transfers when TLS is in the pipeline;
+ * data must explicitly be pulled into user-space memory for TLS encryption to work.
+ *
+ * 3) compressed sstable, transferred without SSL/TLS - data can be streamed via zero-copy transfer as the data does not
+ * need to be manipulated (it can be sent "as-is").
+ *
+ * <h3>Compressing the data</h3>
+ * We always want to transfer as few bytes as possible of the wire when streaming a file. If the
+ * sstable is not already compressed via table compression options, we apply an on-the-fly stream compression
+ * to the data. The stream compression format is documented in
+ * {@link org.apache.cassandra.streaming.async.StreamCompressionSerializer}
+ *
+ * You may be wondering: why implement your own compression scheme? why not use netty's built-in compression codecs,
+ * like {@link io.netty.handler.codec.compression.Lz4FrameEncoder}? That makes complete sense if all the sstables
+ * to be streamed are non using sstable compression (and obviously you wouldn't use stream compression when the sstables
+ * are using sstable compression). The problem is when you have a mix of files, some using sstable compression
+ * and some not. You can either:
+ *
+ * - send the files of one type over one kind of socket, and the others over another socket
+ * - send them both over the same socket, but then auto-adjust per each file type.
+ *
+ * I've opted for the latter to keep socket/channel management simpler and cleaner.

+/**
+ * Represents a ready and post-handshake channel that can send outbound messages. This class groups a netty channel
+ * with any other channel-related information we track and, most importantly, handles the details on when the channel is flushed.
+ *
+ * <h2>Flushing</h2>
+ *
+ * We don't flush to the socket on every message as it's a bit of a performance drag (making the system call, copying
+ * the buffer, sending out a small packet). Thus, by waiting until we have a decent chunk of data (for some definition
+ * of 'decent'), we can achieve better efficiency and improved performance (yay!).
+ * <p>
+ * When to flush mainly depends on whether we use message coalescing or not (see {@link CoalescingStrategies}).
+ * <p>
+ * Note that the callback functions are invoked on the netty event loop, which is (in almost all cases) different
+ * from the thread that will be invoking {@link #write(QueuedMessage, boolean)}.
+ *
+ * <h3>Flushing without coalescing</h3>
+ *
+ * When no coalescing is in effect, we want to send new message "right away". However, as said above, flushing after
+ * every message would be particularly inefficient when there is lots of message in our sending queue, and so in
+ * practice we want to flush in 2 cases:
+ * 1) After any message <b>if</b> there is no pending message in the send queue.
+ * 2) When we've filled up or exceeded the netty outbound buffer (see {@link ChannelOutboundBuffer})
+ * <p>
+ * The second part is relatively simple and handled generically in {@link MessageOutHandler#write(ChannelHandlerContext, Object, ChannelPromise)} [1].
+ * The first part however is made a little more complicated by how netty's event loop executes. It is woken up by
+ * external callers to the channel invoking a flush, via either {@link Channel#flush} or one of the {@link Channel#writeAndFlush}
+ * methods [2]. So a plain {@link Channel#write} will only queue the message in the channel, and not wake up the event loop.
+ * <p>
+ * This means we don't want to simply call {@link Channel#write} as we want the message processed immediately. But we
+ * also don't want to flush on every message if there is more in the sending queue, so simply calling
+ * {@link Channel#writeAndFlush} isn't completely appropriate either. In practice, we handle this by calling
+ * {@link Channel#writeAndFlush} (so the netty event loop <b>does</b> wake up), but we override the flush behavior so
+ * it actually only flushes if there are no pending messages (see how {@link MessageOutHandler#flush} delegates the flushing
+ * decision back to this class through {@link #onTriggeredFlush}, and how {@link SimpleChannelWriter} makes this a no-op;
+ * instead {@link SimpleChannelWriter} flushes after any message if there are no more pending ones in
+ * {@link #onMessageProcessed}).
+ *
+ * <h3>Flushing with coalescing</h3>
+ *
+ * The goal of coalescing is to (artificially) delay the flushing of data in order to aggregate even more data before
+ * sending a group of packets out. So we don't want to flush after messages even if there is no pending messages in the
+ * sending queue, but we rather want to delegate the decision on when to flush to the {@link CoalescingStrategy}. In
+ * pratice, when coalescing is enabled we will flush in 2 cases:
+ * 1) When the coalescing strategies decides that we should.
+ * 2) When we've filled up or exceeded the netty outbound buffer ({@link ChannelOutboundBuffer}), exactly like in the
+ * no coalescing case.
+ * <p>
+ * The second part is handled exactly like in the no coalescing case, see above.
+ * The first part is handled by {@link CoalescingChannelWriter#write(QueuedMessage, boolean)}. Whenever a message is sent, we check
+ * if a flush has been already scheduled by the coalescing strategy. If one has, we're done, otherwise we ask the
+ * strategy when the next flush should happen and schedule one.
+ *
+ *<h2>Message timeouts and retries</h2>
+ *
+ * The main outward-facing method is {@link #write(QueuedMessage, boolean)}, where callers pass a
+ * {@link QueuedMessage}. If a message times out, as defined in {@link QueuedMessage#isTimedOut()},
+ * the message listener {@link #handleMessageFuture(Future, QueuedMessage, boolean)} is invoked
+ * with the cause being a {@link ExpiredException}. The message is not retried and it is dropped on the floor.
+ * <p>
+ * If there is some {@link IOException} on the socket after the message has been written to the netty channel,
+ * the message listener {@link #handleMessageFuture(Future, QueuedMessage, boolean)} is invoked
+ * and 1) we check to see if the connection should be re-established, and 2) possibly createRetry the message.
+ *
+ * <h2>Failures</h2>
+ *
+ * <h3>Failure to make progress sending bytes</h3>
+ * If we are unable to make progress sending messages, we'll receive a netty notification
+ * ({@link IdleStateEvent}) at {@link MessageOutHandler#userEventTriggered(ChannelHandlerContext, Object)}.
+ * We then want to close the socket/channel, and purge any messages in {@link OutboundMessagingConnection#backlog}
+ * to try to free up memory as quickly as possible. Any messages in the netty pipeline will be marked as fail
+ * (as we close the channel), but {@link MessageOutHandler#userEventTriggered(ChannelHandlerContext, Object)} also
+ * sets a channel attribute, {@link #PURGE_MESSAGES_CHANNEL_ATTR} to true. This is essentially as special flag
+ * that we can look at in the promise handler code ({@link #handleMessageFuture(Future, QueuedMessage, boolean)})
+ * to indicate that any backlog should be thrown away.
+ *
+ * <h2>Notes</h2>
+ * [1] For those desperately interested, and only after you've read the entire class-level doc: You can register a custom
+ * {@link MessageSizeEstimator} with a netty channel. When a message is written to the channel, it will check the
+ * message size, and if the max ({@link ChannelOutboundBuffer}) size will be exceeded, a task to signal the "channel
+ * writability changed" will be executed in the channel. That task, however, will wake up the event loop.
+ * Thus if coalescing is enabled, the event loop will wake up prematurely and process (and possibly flush!) the messages
+ * currently in the queue, thus defeating an aspect of coalescing. Hence, we're not using that feature of netty.
+ * [2]: The netty event loop is also woken up by it's internal timeout on the epoll_wait() system call.

/**
* Handles the streaming a one or more section of one of more sstables to and from a specific
- * remote node.
+ * remote node. The sending side performs a block-level transfer of the source sstable, while the receiver
+ * must deserilaize that data stream into an partitions and rows, and then write that out as an sstable.
*
- * Both this node and the remote one will create a similar symmetrical StreamSession. A streaming
+ * Both this node and the remote one will create a similar symmetrical {@link StreamSession}. A streaming
* session has the following life-cycle:
*
- * 1. Connections Initialization
+ * 1. Session Initialization
*
- * (a) A node (the initiator in the following) create a new StreamSession, initialize it (init())
- * and then start it (start()). Start will create a {@link ConnectionHandler} that will create
- * two connections to the remote node (the follower in the following) with whom to stream and send
- * a StreamInit message. The first connection will be the incoming connection for the
- * initiator, and the second connection will be the outgoing.
- * (b) Upon reception of that StreamInit message, the follower creates its own StreamSession,
- * initialize it if it still does not exist, and attach connecting socket to its ConnectionHandler
- * according to StreamInit message's isForOutgoing flag.
- * (d) When the both incoming and outgoing connections are established, StreamSession calls
- * StreamSession#onInitializationComplete method to start the streaming prepare phase
- * (StreamResultFuture.startStreaming()).
+ * (a) A node (the initiator in the following) create a new {@link StreamSession},
+ * initialize it {@link #init(StreamResultFuture)}, and then start it ({@link #start()}).
+ * Starting a session causes a {@link StreamInitMessage} to be sent.
+ * (b) Upon reception of that {@link StreamInitMessage}, the follower creates its own {@link StreamSession},
+ * and initializes it if it still does not exist.
+ * (c) After the initiator sends the {@link StreamInitMessage}, it invokes
+ * {@link StreamSession#onInitializationComplete()} to start the streaming prepare phase.
*
* 2. Streaming preparation phase
*
- * (a) This phase is started when the initiator onInitializationComplete() method is called. This method sends a
- * PrepareMessage that includes what files/sections this node will stream to the follower
- * (stored in a StreamTransferTask, each column family has it's own transfer task) and what
- * the follower needs to stream back (StreamReceiveTask, same as above). If the initiator has
- * nothing to receive from the follower, it goes directly to its Streaming phase. Otherwise,
- * it waits for the follower PrepareMessage.
- * (b) Upon reception of the PrepareMessage, the follower records which files/sections it will receive
- * and send back its own PrepareMessage with a summary of the files/sections that will be sent to
- * the initiator (prepare()). After having sent that message, the follower goes to its Streamning
- * phase.
- * (c) When the initiator receives the follower PrepareMessage, it records which files/sections it will
- * receive and then goes to his own Streaming phase.
+ * (a) A {@link PrepareSynMessage} is sent that includes a) what files/sections this node will stream to the follower
+ * (stored locally in a {@link StreamTransferTask}, one for each table) and b) what the follower needs to
+ * stream back (stored locally in a {@link StreamReceiveTask}, one for each table).
+ * (b) Upon reception of the {@link PrepareSynMessage}, the follower records which files/sections it will receive
+ * and send back a {@link PrepareSynAckMessage}, which contains a summary of the files/sections that will be sent to
+ * the initiator.
+ * (c) When the initiator receives the {@link PrepareSynAckMessage}, it records which files/sections it will
+ * receive, and then goes to it's Streaming phase (see next section). If the intiator is to receive files,
+ * it sends a {@link PrepareAckMessage} to the follower to indicate that it can start streaming to the initiator.
+ * (d) (Optional) If the follower receives a {@link PrepareAckMessage}, it enters it's Streaming phase.
*
* 3. Streaming phase
*
- * (a) The streaming phase is started by each node (the sender in the follower, but note that each side
- * of the StreamSession may be sender for some of the files) involved by calling startStreamingFiles().
- * This will sequentially send a FileMessage for each file of each SteamTransferTask. Each FileMessage
- * consists of a FileMessageHeader that indicates which file is coming and then start streaming the
- * content for that file (StreamWriter in FileMessage.serialize()). When a file is fully sent, the
- * fileSent() method is called for that file. If all the files for a StreamTransferTask are sent
- * (StreamTransferTask.complete()), the task is marked complete (taskCompleted()).
- * (b) On the receiving side, a SSTable will be written for the incoming file (StreamReader in
- * FileMessage.deserialize()) and once the FileMessage is fully received, the file will be marked as
- * complete (received()). When all files for the StreamReceiveTask have been received, the sstables
- * are added to the CFS (and 2ndary index are built, StreamReceiveTask.complete()) and the task
- * is marked complete (taskCompleted())
+ * (a) The streaming phase is started at each node by calling {@link StreamSession#startStreamingFiles(boolean)}.
+ * This will send, sequentially on each outbound streaming connection (see {@link NettyStreamingMessageSender}),
+ * an {@link OutgoingFileMessage} for each file in each of the {@link StreamTransferTask}.
+ * Each {@link OutgoingFileMessage} consists of a {@link FileMessageHeader} that contains metadata about the file
+ * being streamed, followed by the file content itself. Once all the files for a {@link StreamTransferTask} are sent,
+ * the task is marked complete {@link StreamTransferTask#complete(int)}.
+ * (b) On the receiving side, a SSTable will be written for the incoming file, and once the file is fully received,
+ * the file will be marked as complete ({@link StreamReceiveTask#received(SSTableMultiWriter)}). When all files
+ * for the {@link StreamReceiveTask} have been received, the sstables are added to the CFS (and 2ndary indexes/MV are built),
+ * and the task is marked complete ({@link #taskCompleted(StreamReceiveTask)}).
* (b) If during the streaming of a particular file an error occurs on the receiving end of a stream
- * (FileMessage.deserialize), the node will send a SessionFailedMessage to the sender and close the stream session.
- * (c) When all transfer and receive tasks for a session are complete, the move to the Completion phase
- * (maybeCompleted()).
+ * (it may be either the initiator or the follower), the node will send a {@link SessionFailedMessage}
+ * to the sender and close the stream session.
+ * (c) When all transfer and receive tasks for a session are complete, the session moves to the Completion phase
+ * ({@link #maybeCompleted()}).
*
* 4. Completion phase
*
- * (a) When a node has finished all transfer and receive task, it enter the completion phase (maybeCompleted()).
- * If it had already received a CompleteMessage from the other side (it is in the WAIT_COMPLETE state), that
- * session is done is is closed (closeSession()). Otherwise, the node switch to the WAIT_COMPLETE state and
- * send a CompleteMessage to the other side.
+ * (a) When a node enters the completion phase, it sends a {@link CompleteMessage} to the peer, and then enter the
+ * {@link StreamSession.State#WAIT_COMPLETE} state. If it has already received a {@link CompleteMessage}
+ * from the peer, session is complete and is then closed ({@link #closeSession(State)}). Otherwise, the node
+ * switch to the {@link StreamSession.State#WAIT_COMPLETE} state and send a {@link CompleteMessage} to the other side.
+ *
+ * In brief, the message passing looks like this (I for initiator, F for follwer):
+ * (session init)
+ * I: StreamInitMessage
+ * (session prepare)
+ * I: PrepareSynMessage
+ * F: PrepareSynAckMessage
+ * I: PrepareAckMessage
+ * (stream - this can happen in both directions)
+ * I: OutgoingFileMessage
+ * F: ReceivedMessage
+ * (completion)
+ * I/F: CompleteMessage
+ *
+ * All messages which derive from {@link StreamMessage} are sent by the standard internode messaging
+ * (via {@link org.apache.cassandra.net.MessagingService}, while the actual files themselves are sent by a special
+ * "streaming" connection type. See {@link NettyStreamingMessageSender} for details. Because of the asynchronous

+ *
+ * One of the challenges when sending files is we might need to delay shipping the file if:
+ *
+ * - we've exceeded our network I/O use due to rate limiting (at the cassandra level)
+ * - the receiver isn't keeping up, which causes the local TCP socket buffer to not empty, which causes epoll writes to not
+ * move any bytes to the socket, which causes buffers to stick around in user-land (a/k/a cassandra) memory.
+ *
+ * When those conditions occur, it's easy enough to reschedule processing the file once the resources pick up
+ * (we acquire the permits from the rate limiter, or the socket drains). However, we need to ensure that
+ * no other messages are submitted to the same channel while the current file is still being processed.
