+.. _swh-graph-grpc-api:
+
+==================
+Using the GRPC API
+==================
+
+The GRPC API is the core API used to query the graph remotely. It uses the
+`GRPC framework <https://grpc.io/>`_ to provide high-performance graph
+traversal methods with server streaming.
+
+It is more expressive than the :ref:`HTTP API <swh-graph-api>` (which itself
+uses the GRPC API under the hood to serve queries), however it can only be
+used internally or with a local setup, and is never exposed publicly.
+
+Its major features include: returning node and edge properties, performing BFS
+traversals, including traversals with more than one starting node, finding
+shortest paths, common ancestors, etc.
+
+Quickstart
+==========
+
+Starting the server
+-------------------
+
+The GRPC server is automatically started on port 50091 when the HTTP server
+is started with ``swh graph rpc-serve``. It can also be started directly with
+Java, instead of going through the Python layer, by using the fat-jar shipped
+with swh-graph:
+
+.. code-block:: console
+
+ $ java -cp swh-graph-XXX.jar org.softwareheritage.graph.rpc.GraphServer <graph_basename>
+
+(See :ref:`swh-graph-java-api` and :ref:`swh-graph-memory` for more
+information on Java process options and JVM tuning.)
+
+Running queries
+---------------
+
+The `gRPC command line tool
+<https://github.com/grpc/grpc/blob/master/doc/command_line_tool.md>`_
+can be an easy way to query the GRPC API from the command line. It is
+invoked with the ``grpc_cli`` command. Of course, it is also possible to use
+a generated RPC client in any programming language supported by GRPC.
+
+All RPC methods are defined in the service ``swh.graph.TraversalService``.
+The available endpoints can be listed with ``ls``:
+
+.. code-block:: console
+
+ $ grpc_cli ls localhost:50091 swh.graph.TraversalService
+ Traverse
+ FindPathTo
+ FindPathBetween
+ CountNodes
+ CountEdges
+ Stats
+ GetNode
+
+A RPC method can be called with the ``call`` subcommand.
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.Stats ""
+ connecting to localhost:50091
+ num_nodes: 21
+ num_edges: 23
+ compression: 1.412
+ bits_per_node: 8.524
+ [...]
+ Rpc succeeded with OK status
+
+The ``--json-output`` flag can also be used to make the results easier to
+parse.
+
+.. code-block:: console
+
+ $ grpc_cli --json_output call localhost:50091 swh.graph.TraversalService.Stats ""
+ connecting to localhost:50091
+ {
+ "numNodes": "21",
+ "numEdges": "23",
+ [...]
+ }
+ Rpc succeeded with OK status
+
+
+**Note**: grpc_cli's outputs in this document are slightly modified for
+readability's sake.
+
+Simple queries
+==============
+
+For a full documentation of all the endpoints, as well as the request and
+response messages, see :ref:`swh-graph-grpc-api-protobuf`.
+
+Querying a single node
+----------------------
+
+The **GetNode** endpoint can be used to return information on a single
+node of the graph, including all its node properties, from its SWHID. Here
+are a few examples from the test graph:
+
+Content
+~~~~~~~
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "swh:1:cnt:0000000000000000000000000000000000000001"'
+
+.. code-block:: javascript
+
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000001"
+ cnt {
+ length: 42
+ is_skipped: false
+ }
+
+Revision
+~~~~~~~~
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "swh:1:rev:0000000000000000000000000000000000000009"'
+
+.. code-block:: javascript
+
+ swhid: "swh:1:rev:0000000000000000000000000000000000000009"
+ rev {
+ author: 2
+ author_date: 1111140840
+ author_date_offset: 120
+ committer: 2
+ committer_date: 1111151950
+ committer_date_offset: 120
+ message: "Add parser"
+ }
+
+Release
+~~~~~~~
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "swh:1:rel:0000000000000000000000000000000000000010"'
+
+.. code-block:: javascript
+
+ swhid: "swh:1:rel:0000000000000000000000000000000000000010"
+ rel {
+ author: 0
+ author_date: 1234564290
+ author_date_offset: 120
+ message: "Version 1.0"
+ }
+
+Origin
+~~~~~~
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "swh:1:ori:83404f995118bd25774f4ac14422a8f175e7a054"'
+
+.. code-block:: javascript
+
+ swhid: "swh:1:ori:83404f995118bd25774f4ac14422a8f175e7a054"
+ ori {
+ url: "https://example.com/swh/graph"
+ }
+
+
+Checking the presence of a node
+-------------------------------
+
+The **GetNode** endpoint can also be used to check if a node exists in the
+graph. The RPC will return the ``INVALID_ARGUMENT`` code, and a detailed error
+message.
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "swh:1:ori:ffffffffffffffffffffffffffffffffffffffff"'
+ Rpc failed with status code 3, error message: Unknown SWHID: swh:1:ori:ffffffffffffffffffffffffffffffffffffffff
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "invalidswhid"'
+ Rpc failed with status code 3, error message: malformed SWHID: swh:1:ori:ffffffffffffffffffffffffffffffffffffffff
+
+
+Selecting returned fields with FieldMask
+----------------------------------------
+
+Many endpoints, including **GetNode**, contain a ``mask`` field of type
+`FieldMask
+<https://developers.google.com/protocol-buffers/docs/reference/java/com/google/protobuf/FieldMask.html>`_,
+which can be used to select which fields should be returned in the response.
+
+This is particularly interesting for traversal queries that return a large
+number of nodes, because property access is quite costly from the compressed
+graph (at least compared to regular node access). It is therefore recommended
+that clients systematically use FieldMasks to only request the properties that
+they will consume.
+
+A FieldMask is represented as a set of "field paths" in dotted notation. For
+instance, ``paths: ["swhid", "rev.message"]`` will only request the swhid and
+the message of a given node. An empty mask will return an empty object.
+
+Example:
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "swh:1:rev:0000000000000000000000000000000000000009", mask: {paths: ["swhid"]}'
+ swhid: "swh:1:rev:0000000000000000000000000000000000000009"
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.GetNode \
+ 'swhid: "swh:1:rev:0000000000000000000000000000000000000009", mask: {paths: ["swhid", "rev.message", "rev.author"]}'
+ swhid: "swh:1:rev:0000000000000000000000000000000000000009"
+ rev {
+ author: 2
+ message: "Add parser"
+ }
+
+
+Getting statistics on the graph
+-------------------------------
+
+The **Stats** endpoint returns overall statistics on the entire compressed
+graph. Most notably, the total number of nodes and edges, as well as the
+range of indegrees and outdegrees, and some compression-related statistics.
+
+.. code-block:: console
+
+ $ grpc_cli --json_output call localhost:50091 swh.graph.TraversalService.Stats ""
+
+.. code-block:: json
+
+ {
+ "numNodes": "21",
+ "numEdges": "23",
+ "compression": 1.412,
+ "bitsPerNode": 8.524,
+ "bitsPerEdge": 7.783,
+ "avgLocality": 2.522,
+ "indegreeMax": "3",
+ "indegreeAvg": 1.0952380952380953,
+ "outdegreeMax": "3",
+ "outdegreeAvg": 1.0952380952380953
+ }
+
+
+Graph traversals
+================
+
+Breadth-first traversal
+-----------------------
+
+The **Traverse** endpoint performs a breadth-first traversal from a set of
+source nodes, and `streams
+<https://grpc.io/docs/what-is-grpc/core-concepts/#server-streaming-rpc>`_ all
+the nodes it encounters on the way. All the node properties are stored in the
+result nodes. Additionally, the *edge properties* (e.g., directory entry names
+and permissions) are stored as a list in the ``successor`` field of each node.
+
+For instance, here we run a traversal from a directory that contains two
+contents:
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.Traverse \
+ "src: 'swh:1:dir:0000000000000000000000000000000000000006'"
+
+We get the following stream of nodes: first, the source directory (including
+its properties, successor list and their labels), then the contents themselves
+and their respective properties.
+
+.. code-block:: javascript
+
+ swhid: "swh:1:dir:0000000000000000000000000000000000000006"
+ successor {
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000005"
+ label {
+ name: "parser.c"
+ permission: 33188
+ }
+ }
+ successor {
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000004"
+ label {
+ name: "README.md"
+ permission: 33188
+ }
+ }
+ num_successors: 2
+
+.. code-block:: javascript
+
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000005"
+ cnt {
+ length: 1337
+ is_skipped: false
+ }
+
+.. code-block:: javascript
+
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000004"
+ cnt {
+ length: 404
+ is_skipped: false
+ }
+
+Again, it is possible to use a FieldMask to restrict which fields get returned.
+For instance, if we only care about the SWHIDs:
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.Traverse \
+ "src: 'swh:1:dir:0000000000000000000000000000000000000006', mask: {paths: ['swhid']}"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000006"
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000005"
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000004"
+
+
+Graph direction
+~~~~~~~~~~~~~~~
+
+For many purposes, especially that of finding the provenance of software
+artifacts, it is useful to query the backward (or transposed) graph instead,
+which is the same as the forward graph except all the edges are reversed.
+To achieve this, the ``direction`` field can be used to specify a direction
+from the ``GraphDirection`` enum (either ``FORWARD`` or ``BACKWARD``).
+
+This query returns all the nodes reachable from a given directory in the
+*transposed* (or "backward") graph:
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.Traverse \
+ "src: 'swh:1:dir:0000000000000000000000000000000000000006', direction: BACKWARD, mask: {paths: ['swhid']}"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000006"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000008"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000012"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000009"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000013"
+ swhid: "swh:1:rel:0000000000000000000000000000000000000010"
+ swhid: "swh:1:snp:0000000000000000000000000000000000000020"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000018"
+ swhid: "swh:1:ori:83404f995118bd25774f4ac14422a8f175e7a054"
+ swhid: "swh:1:rel:0000000000000000000000000000000000000019"
+
+
+Edge restrictions
+~~~~~~~~~~~~~~~~~
+
+To constrain the kinds of edges can be followed during the graph traversal, it
+is possible to specify an edge restriction string in the ``edge`` field.
+It is a comma-separated list of edge types that will be followed (e.g.
+``"rev:dir,dir:cnt"`` to only follow revision → directory and directory →
+content edges).
+By default (or when ``"*"`` is provided), all edges can be followed.
+
+This query traverses the parent revisions of a given revision only (i.e., it
+outputs the *commit log* from a given commit):
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.Traverse \
+ "src: 'swh:1:rev:0000000000000000000000000000000000000018', edges: 'rev:rev', mask: {paths: ['swhid']}"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000018"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000013"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000009"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000003"
+
+
+Limiting the traversal
+~~~~~~~~~~~~~~~~~~~~~~
+
+To avoid using up too much memory or resources, a traversal can be limited
+in two different ways:
+
+- the ``max_depth`` attribute defines the maximum depth of the traversal.
+- the ``max_edges`` attribute defines the maximum number of edges that can be
+ fetched by the traversal.
+
+When these limits are reached, the traversal will simply stop. While these
+options have obvious use-cases for anti-abuse, they can also be semantically
+useful: for instance, specifying ``max_depth: 1`` will only return the
+*neighbors* of the source node.
+
+
+Filtering returned nodes
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+In many cases, clients might not want to get all the traversed nodes in the
+response stream. With the ``return_nodes`` field (of type ``NodeFilter``), it
+is possible to specify various *criteria* for which nodes should be sent to the
+stream. By default, all nodes are returned.
+
+One common filter is to only want specific *node types* to be returned, which
+can be done with the ``types`` field of ``NodeFilter``. This field contains a
+node type restriction string (e.g. "dir,cnt,rev"), and defaults to "*" (all).
+For instance, to find the list of origins in which a given directory can be
+found:
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.Traverse \
+ "src: 'swh:1:dir:0000000000000000000000000000000000000006', return_nodes: {types: 'ori'}, direction: BACKWARD, mask: {paths: ['swhid']}"
+ swhid: "swh:1:ori:83404f995118bd25774f4ac14422a8f175e7a054"
+
+
+Traversal from multiple sources
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Traversals can have multiple starting nodes, when multiple source nodes are
+present in the ``src`` field. For instance, this BFS starts from two different
+directories, and explores the graph in parallel from these multiple starting
+points:
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.Traverse \
+ "src: ['swh:1:dir:0000000000000000000000000000000000000006', 'swh:1:dir:0000000000000000000000000000000000000017'], mask: {paths: ['swhid']}"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000006"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000017"
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000005"
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000004"
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000014"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000016"
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000015"
+
+
+Finding a path to a node matching a criteria
+--------------------------------------------
+
+The **FindPathTo** endpoint searches for a shortest path between a set of
+source nodes and any node that matches a specific *criteria*.
+It does so by performing a breadth-first search from the source node,
+until any node that matches the given criteria is found, then follows
+back its parents to return a shortest path from the source set to that
+node.
+
+The criteria can be specified in the ``target`` field of the
+``FindPathToRequest``, which is of type ``NodeFilter``.
+
+As an example, a common use-case for content provenance is to find the shortest
+path of a content to an origin in the transposed graph. This query can be
+run like this:
+
+.. code-block:: console
+
+ $ grpc_cli call localhost:50091 swh.graph.TraversalService.FindPathTo \
+ "src: 'swh:1:cnt:0000000000000000000000000000000000000001', target: {types: 'ori'}, direction: BACKWARD, mask: {paths: ['swhid']}"
+ swhid: "swh:1:cnt:0000000000000000000000000000000000000001"
+ swhid: "swh:1:dir:0000000000000000000000000000000000000008"
+ swhid: "swh:1:rev:0000000000000000000000000000000000000009"
+ swhid: "swh:1:snp:0000000000000000000000000000000000000020"
+ swhid: "swh:1:ori:83404f995118bd25774f4ac14422a8f175e7a054"
+
+As soon as the request finds an origin, it stops and returns the path from the
+source set to this origin.
+
+Similar to the **Traverse** endpoint, it is possible to specify edge
+restrictions, graph directions, as well as multiple source nodes.
+
+
+Finding a path between two sets of nodes
+----------------------------------------
+
+The **FindPathBetween** endpoint searches for a shortest path between a set of
+source nodes and a set of destination nodes.
+
+It does so by performing a *bidirectional breadth-first search*, i.e.,
+two parallel breadth-first searches, one from the source set ("src-BFS")
+and one from the destination set ("dst-BFS"), until both searches find a
+common node that joins their visited sets. This node is called the
+"midpoint node".
+The path returned is the path src -> ... -> midpoint -> ... -> dst,
+which is always a shortest path between src and dst.
+
+The graph direction of both BFS can be configured separately. By
+default, the dst-BFS will use the graph in the opposite direction than
+the src-BFS (if direction = FORWARD, by default direction_reverse =
+BACKWARD, and vice-versa). The default behavior is thus to search for
+a shortest path between two nodes in a given direction. However, one
+can also specify FORWARD or BACKWARD for *both* the src-BFS and the
+dst-BFS. This will search for a common descendant or a common ancestor
+between the two sets, respectively. These will be the midpoints of the
+returned path.
+
+Similar to the **Traverse** endpoint, it is also possible to specify edge
+restrictions.
+
+**Example 1**: shortest path from a snapshot to a content (forward graph):
+
+.. code-block:: console
