/3.0/PROTOCOL.md:
--------------------------------------------------------------------------------
  1 | # Protocol 3.0 (rev. 2)
  2 | 
  3 | This documentation describes the communication protocol between Moleculer nodes.
  4 | 
  5 | **Variables in topic names:**
  6 | 
  7 | - `<namespace>` - Namespace from broker options
  8 | - `<nodeID>` - Target nodeID
  9 | - `<action>` - Action name. E.g.: `posts.find`
 10 | - `<group>` - Event group name. E.g.: `users`
 11 | - `<event>` - Event name. E.g.: `user.created`
 12 | 
 13 | ## Subscriptions
 14 | 
 15 | After the client is connected to the message broker (NATS, Redis, MQTT), it subscribes to the following topics:
 16 | 
 17 | | Type                 | Topic name              |
 18 | | -------------------- | ----------------------- |
 19 | | Event                | `MOL.EVENT.<nodeID>`    |
 20 | | Event (balanced)     | `MOL.EVENTB.<event>`    |
 21 | | Request              | `MOL.REQ.<nodeID>`      |
 22 | | Request (balanced)   | `MOL.REQB.<action>`     |
 23 | | Response             | `MOL.RES.<nodeID>`      |
 24 | | Discover             | `MOL.DISCOVER`          |
 25 | | Discover (targetted) | `MOL.DISCOVER.<nodeID>` |
 26 | | Info                 | `MOL.INFO`              |
 27 | | Info (targetted)     | `MOL.INFO.<nodeID>`     |
 28 | | Heartbeat            | `MOL.HEARTBEAT`         |
 29 | | Ping                 | `MOL.PING`              |
 30 | | Ping (targetted)     | `MOL.PING.<nodeID>`     |
 31 | | Pong                 | `MOL.PONG.<nodeID>`     |
 32 | | Disconnect           | `MOL.DISCONNECT`        |
 33 | 
 34 | > If `namespace` is defined, the topic prefix is `MOL-namespace` instead of `MOL`. For example: `MOL-dev.EVENT` if the namespace is `dev`.
 35 | 
 36 | ## Discovering
 37 | 
 38 | After subscriptions, the client broadcasts a `DISCOVER` packet. In response to this, all connected nodes send back `INFO` packet to the sender node. From these responses, the client builds its own service registry. At last, the client broadcasts own INFO packet to all other nodes.
 39 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_discover.png)
 40 | 
 41 | ## Heartbeat
 42 | 
 43 | The client has to broadcast `HEARTBEAT` packets periodically. The period value comes from broker options (`heartbeatInterval`). The default value is 5 secs.
 44 | If the client does not receive `HEARTBEAT` for `heartbeatTimeout` seconds from a node, marks it broken and doesn't route requests to this node.
 45 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_heartbeat.png)
 46 | 
 47 | ## Request-reply
 48 | 
 49 | When you call the `broker.call` method, the broker sends a `REQUEST` packet to the targetted node. It processes the request and sends back a `RESPONSE` packet to the requester node.
 50 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_request.png)
 51 | 
 52 | ## Event
 53 | 
 54 | When you call the `broker.emit` method, the broker sends an `EVENT` packet to the subscriber nodes. The broker groups & balances the subscribers, so only one instance per service receives the event. If you call the `broker.broadcast` method, the broker sends an `ĘVENT` packet to all subscriber nodes. It doesn't group & balance the subscribers.
 55 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_event.png)
 56 | 
 57 | ## Ping-pong
 58 | 
 59 | When you call the `broker.ping` method, the broker sends a `PING` packet to the targetted node. If node is not defined, it sends to all nodes. If the client receives the `PING` packet, sends back a `PONG` response packet. If it receives, broker broadcasts a local `$node.pong` event to the local services.
 60 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_pong.png)
 61 | 
 62 | ## Disconnect
 63 | 
 64 | When a node is stopping, it broadcasts a `DISCONNECT` packet to all nodes.

/5.0/PROTOCOL.md:
--------------------------------------------------------------------------------
  1 | # Protocol 5.0 (rev. 1)
  2 | 
  3 | This protocol is used to communicate between the Moleculer nodes.
  4 | 
  5 | ## Concept
  6 | 
  7 | ### Subscriptions
  8 | 
  9 | After the client is connected to the message broker (NATS, Redis, MQTT), it subscribes to the following topics:
 10 | 
 11 | | Type                | Topic name              |
 12 | | ------------------- | ----------------------- |
 13 | | Event               | `MOL.EVENT.<nodeID>`    |
 14 | | Event (balanced)    | `MOL.EVENTB.<event>`    |
 15 | | Request             | `MOL.REQ.<nodeID>`      |
 16 | | Request (balanced)  | `MOL.REQB.<action>`     |
 17 | | Response            | `MOL.RES.<nodeID>`      |
 18 | | Discover            | `MOL.DISCOVER`          |
 19 | | Discover (targeted) | `MOL.DISCOVER.<nodeID>` |
 20 | | Info                | `MOL.INFO`              |
 21 | | Info (targeted)     | `MOL.INFO.<nodeID>`     |
 22 | | Heartbeat           | `MOL.HEARTBEAT`         |
 23 | | Ping                | `MOL.PING`              |
 24 | | Ping (targeted)     | `MOL.PING.<nodeID>`     |
 25 | | Pong                | `MOL.PONG.<nodeID>`     |
 26 | | Disconnect          | `MOL.DISCONNECT`        |
 27 | 
 28 | > If `namespace` is defined, the topic prefix is `MOL-<namespace>` instead of `MOL`. E.g.: `MOL-dev.EVENT` when the namespace is `dev`.
 29 | 
 30 | **Variables in topic names:**
 31 | 
 32 | - `<namespace>` - Namespace from broker options
 33 | - `<nodeID>` - Target nodeID
 34 | - `<action>` - Action name. E.g.: `posts.find`
 35 | - `<group>` - Event group name. E.g.: `users`
 36 | - `<event>` - Event name. E.g.: `user.created`
 37 | 
 38 | ### Discovering
 39 | 
 40 | After subscribing, the transporter broadcasts a `DISCOVER` packet. In response to this, all connected nodes send back `INFO` packet to the sender node. From these responses, the client builds its own service registry. At last, the client broadcasts own INFO packet to all other nodes.
 41 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_discover.png)
 42 | 
 43 | ### Heartbeat
 44 | 
 45 | The client has to broadcast `HEARTBEAT` packets periodically. The period value comes from broker options (`heartbeatInterval`). The default value is 5 secs.
 46 | If the client does not receive `HEARTBEAT` for `heartbeatTimeout` seconds from a node, marks it broken and doesn't route requests to this node.
 47 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_heartbeat.png)
 48 | 
 49 | ### Request-reply
 50 | 
 51 | When you call the `broker.call` method, the broker sends a `REQUEST` packet to the targeted node. It processes the request and sends back a `RESPONSE` packet to the requester node.
 52 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_request.png)
 53 | 
 54 | ### Event
 55 | 
 56 | When you call the `broker.emit` method, the broker sends an `EVENT` packet to the subscriber nodes. The broker groups & balances the subscribers, so only one instance per service receives the event. If you call the `broker.broadcast` method, the broker sends an `ĘVENT` packet to all subscriber nodes. It doesn't balance the subscribers.
 57 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_event.png)
 58 | 
 59 | ### Ping-pong
 60 | 
 61 | When you call the `broker.ping` method, the broker sends a `PING` packet to the targeted node. If node is not defined, it sends to all nodes. If the client receives the `PING` packet, sends back a `PONG` response packet. If it receives, broker broadcasts a local `$node.pong` event to the local services.
 62 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_pong.png)
 63 | 
 64 | ### Disconnect
 65 | 
 66 | When a node is stopping, it broadcasts a `DISCONNECT` packet to all nodes.
 67 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_disconnect.png)
 68 | 
 69 | ## Protocol messages
 70 | 
 71 | ### `DISCOVER`
 72 | 
 73 | When the transporter established the connection with the message broker, it broadcasts a `DISCOVER` message to all other nodes.
 74 | 
 75 | **Topic name:**
 76 | 
 77 | - `MOL.DISCOVER` (if broadcasts)
 78 | - `MOL.DISCOVER.node-1` (if sent only to `node-1`)
 79 | - `MOL-dev.DISCOVER` (if namespace is `dev`)
 80 | 
 81 | **Fields:**
 82 | 
 83 | | Field    | Type     | Required | Description       |
 84 | | -------- | -------- | -------- | ----------------- |
 85 | | `ver`    | `string` | ✔        | Protocol version. |
 86 | | `sender` | `string` | ✔        | Sender nodeID.    |
 87 | 
 88 | **Example with JSON serializer**
 89 | 
 90 | ```json
 91 | {
 92 |   "ver": "5",
 93 |   "sender": "node-100"
 94 | }
 95 | ```
 96 | 
 97 | ### `INFO`
 98 | 
 99 | When the node receives an `INFO` packet, it sends an `INFO` packet which contains all mandatory information about the nodes and the loaded services.
100 | 
101 | **Topic name:**
102 | 
103 | - `MOL.INFO` (if broadcasts)
104 | - `MOL.INFO.node-1` (if sent only to `node-1`)
105 | - `MOL-dev.INFO` (if namespace is `dev`)
106 | 
107 | **Fields:**
108 | 
109 | | Field                | Type       | Required | Description                                           |

444 | ## Graceful starting & stopping
445 | 
446 | ### Start
447 | 
448 | The broker starts by establishing connection with the `transporter` (e.g., NATS server, MQTT broker). After successfully establishing the connection, it starts all services, i.e., calls service `started` handlers. Once all services have started successfully, broker publishes the local service list to remote nodes. Hence remote nodes will send requests only after all local service have started properly.
449 | 
450 | **Start lifecycle sequence**
451 | 
452 | ![image](media/broker-start.svg)
453 | 
454 | ### Stop
455 | 
456 | When broker is stopping, it starts by publishing an empty service list to all remote nodes. This is done to inform all remote nodes that the node and it's service will be shut down. Next, broker starts stopping all local services. After that, the transporter disconnects.
457 | 
458 | **Stop lifecycle sequence**
459 | 
460 | ![image](media/broker-stop.svg)
461 | 
462 | ## Streams
463 | 
464 | While transferring streams, sequence number (`seq`) field is used to keep track of the chunks and their order. This is especially important in "multi-threaded systems" that can shuffle the packets before sending them. If packets arrive unordered they are stored in a pool until previous chucks arrive.
465 | > The `seq = 0` is the first initial package and it has `params`, `headers` and `meta` properties. This package doesn't contain stream data.
466 | 
467 | ## Disabled built-in balancer mode
468 | 
469 | When built-in load balancing mechanisms are disabled, the balancing is done by the brokers (e.g., NATS, RabbitMQ). This means that there are no local calls in actions and events. All requests are transferred to transporter that will be responsible for choosing the destination of the request and delivery of the message.
470 | 
471 | ## Changes from version `4`
472 |

  1 | # Protocol 4.0 (rev. 1)
  2 | 
  3 | This protocol is used to communicate between the Moleculer nodes.
  4 | 
  5 | ## Concept
  6 | 
  7 | ### Subscriptions
  8 | 
  9 | After the client is connected to the message broker (NATS, Redis, MQTT), it subscribes to the following topics:
 10 | 
 11 | | Type                | Topic name              |
 12 | | ------------------- | ----------------------- |
 13 | | Event               | `MOL.EVENT.<nodeID>`    |
 14 | | Event (balanced)    | `MOL.EVENTB.<event>`    |
 15 | | Request             | `MOL.REQ.<nodeID>`      |
 16 | | Request (balanced)  | `MOL.REQB.<action>`     |
 17 | | Response            | `MOL.RES.<nodeID>`      |
 18 | | Discover            | `MOL.DISCOVER`          |
 19 | | Discover (targeted) | `MOL.DISCOVER.<nodeID>` |
 20 | | Info                | `MOL.INFO`              |
 21 | | Info (targeted)     | `MOL.INFO.<nodeID>`     |
 22 | | Heartbeat           | `MOL.HEARTBEAT`         |
 23 | | Ping                | `MOL.PING`              |
 24 | | Ping (targeted)     | `MOL.PING.<nodeID>`     |
 25 | | Pong                | `MOL.PONG.<nodeID>`     |
 26 | | Disconnect          | `MOL.DISCONNECT`        |
 27 | 
 28 | > If `namespace` is defined, the topic prefix is `MOL-<namespace>` instead of `MOL`. E.g.: `MOL-dev.EVENT` when the namespace is `dev`.
 29 | 
 30 | **Variables in topic names:**
 31 | 
 32 | - `<namespace>` - Namespace from broker options
 33 | - `<nodeID>` - Target nodeID
 34 | - `<action>` - Action name. E.g.: `posts.find`
 35 | - `<group>` - Event group name. E.g.: `users`
 36 | - `<event>` - Event name. E.g.: `user.created`
 37 | 
 38 | ### Discovering
 39 | 
 40 | After subscribing, the transporter broadcasts a `DISCOVER` packet. In response to this, all connected nodes send back `INFO` packet to the sender node. From these responses, the client builds its own service registry. At last, the client broadcasts own INFO packet to all other nodes.

 42 | 
 43 | ### Heartbeat
 44 | 
 45 | The client has to broadcast `HEARTBEAT` packets periodically. The period value comes from broker options (`heartbeatInterval`). The default value is 5 secs.
 46 | If the client does not receive `HEARTBEAT` for `heartbeatTimeout` seconds from a node, marks it broken and doesn't route requests to this node.

 48 | 
 49 | ### Request-reply
 50 | 
 51 | When you call the `broker.call` method, the broker sends a `REQUEST` packet to the targeted node. It processes the request and sends back a `RESPONSE` packet to the requester node.
 52 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_request.png)
 53 | 
 54 | ### Event
 55 | 
 56 | When you call the `broker.emit` method, the broker sends an `EVENT` packet to the subscriber nodes. The broker groups & balances the subscribers, so only one instance per service receives the event. If you call the `broker.broadcast` method, the broker sends an `ĘVENT` packet to all subscriber nodes. It doesn't balance the subscribers.
 57 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_event.png)
 58 | 
 59 | ### Ping-pong
 60 | 
 61 | When you call the `broker.ping` method, the broker sends a `PING` packet to the targeted node. If node is not defined, it sends to all nodes. If the client receives the `PING` packet, sends back a `PONG` response packet. If it receives, broker broadcasts a local `$node.pong` event to the local services.
 62 | ![](http://moleculer.services/images/protocol-v2/moleculer_protocol_pong.png)
 63 | 
 64 | ### Disconnect
 65 | 
 66 | When a node is stopping, it broadcasts a `DISCONNECT` packet to all nodes.

 68 | 
 69 | ## Protocol messages
 70 | 
 71 | ### `DISCOVER`
 72 | 
 73 | When the transporter established the connection with the message broker, it broadcasts a `DISCOVER` message to all other nodes.
 74 | 
 75 | **Topic name:**
 76 | 
 77 | - `MOL.DISCOVER` (if broadcasts)
 78 | - `MOL.DISCOVER.node-1` (if sent only to `node-1`)

 94 | }
 95 | ```
 96 | 
 97 | ### `INFO`
 98 | 
 99 | When the node receives an `INFO` packet, it sends an `INFO` packet which contains all mandatory information about the nodes and the loaded services.

459 | ## Graceful starting & stopping
460 | 
461 | ### Start
462 | 
463 | The broker starts by establishing connection with the `transporter` (e.g., NATS server, MQTT broker). After successfully establishing the connection, it starts all services, i.e., calls service `started` handlers. Once all services have started successfully, broker publishes the local service list to remote nodes. Hence remote nodes will send requests only after all local service have started properly.
464 | 
465 | **Start lifecycle sequence**
466 | 
467 | ![image](media/broker-start.svg)
468 | 
469 | ### Stop
470 | 
471 | When broker is stopping, it starts by publishing an empty service list to all remote nodes. This is done to inform all remote nodes that the node and it's service will be shut down. Next, broker starts stopping all local services. After that, the transporter disconnects.
472 | 
473 | **Stop lifecycle sequence**
474 | 
475 | ![image](media/broker-stop.svg)
476 | 
477 | ## Streams
478 | 
479 | While transferring streams, sequence number (`seq`) field is used to keep track of the chunks and their order. This is especially important in "multi-threaded systems" that can shuffle the packets before sending them. If packets arrive unordered they are stored in a pool until previous chucks arrive.
480 | 
481 | ## Disabled built-in balancer mode
482 | 
483 | When built-in load balancing mechanisms are disabled, the balancing is done by the brokers (e.g., NATS, RabbitMQ). This means that there are no local calls in actions and events. All requests are transferred to transporter that will be responsible for choosing the destination of the request and delivery of the message.
484 | 
485 | ## Changes from version `3`
486 | 
487 | **INFO**
488 | - added `instanceID: string`
489 | - added `metadata: object` specific to each nodes
490 | 
491 | **PING / PONG**
492 | - added messaged ID `id: string` on both message types
493 | 
494 | **REQUEST**
495 | - `params` now is not required anymore 
496 | - removed `metrics` property and added `tracing: boolean` whether tracing events is needed
497 | - new `paramsType: enum` needed for schema-based serializers
498 | - new `caller: string` property for action name of the caller
499 | - new `seq: int32` to have better tracking of stream request
500 | 
501 | **RESPONSE**
502 | - new `dataType: enum` needed for schema-based serializers
503 | - new `seq: int32` to have better tracking of stream request
504 | 
505 | **EVENT**
506 | - added context ID `id: string` in the payload
507 | - new `dataType: enum` needed for schema-based serializers
508 | - new `meta: object` that represents `ctx.meta` object
509 | - added `level: int32` as level of the event
510 | - added `tracing: boolean` whether tracing events is needed
511 | - new `caller: string` property for action/event name of the caller
512 | - added parent context ID `parentID: string`
513 | - added `requestID` from context in the payload
514 | - handled stream requests, hence we have new properties `stream: boolean` whether it's a stream request and `seq: int32` to have better tracking
