Posted by ok...@apache.org.
came up with a clever idea for maintaining order in a distributed traversal. OrdereredTraverser is a wrapper around a Traverser where all methods are delegated to the internal traverser. However, OrderedTraverser has an order() method which returns an int. This allows an ordered stream of traversers to be distributed across machines and then, on return, ordered accordingly. This is much better than the GraphComputer model we have. With OrderedTraverser, we have now exposed OrderTest, DedupTest, and TailTest to gremlin-akka. The final obstacle is nested group()s. There is something super fishy going on with cloning and I'm scared of just banging my head against the wall all morning so I will just let it simmer.

[15/50] [abbrv] tinkerpop git commit: Mark one of the Peer Pressure
tests as non-deterministic.
Posted by ok...@apache.org.
Mark one of the Peer Pressure tests as non-deterministic.
This test tends to fail on certain systems like Travis. By marking it as non-deterministic it will only run when a special system variable is included with the build. CTR

So much. withProcessor(Processor). No more Compute. Process.submit(Graph) as we are now staging it so that every Processor (GraphComputer/GraphAgents) can work over any Graph. This will all be via Partitioner. withComputer() deprecated. Lots of cool stuff with Process strategies -- ProcessorTraveralStrategy like VertexProgramStratgegy and ActorProgramStrategy work directly with TraversalStrategies.GlobalCache. So much other stuf... I forget. Check the CHANGELOG. This was a massive undertaking but, thank god, its all backwards compatible (though with deprecation).

TinkerPop 3.3.0 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* Added `Partitioner` which provides information about how a `Graph` is partitioned.
+* Added `Graph.partitioner()` to access the graph's `Partitioner`.
+* Added `Partition` which is accessible from `Partitioner` and provides `Vertex` and `Edge` iterators for partitions of the `Graph`.
+* Added `GraphActors` which is an asynchronous, partition-centric, distributed, message passing graph processing framework.
+* Added `akka-gremlin/` module which is an Akka implementation of `GraphActors`.
+* Added `Processor` interface and both `GraphActors` and `GraphComputer` extend it.
+* Deprecated `TraversalSource.withComputer()` in favor of `TraversalSource.withProcessor()`.
+* Added `ProcessTraversalStrategy` which is used to get cached strategies associated with a `Processor`.
+* Deprecated `Computer` in favor of `GraphComputer.open()`.
+* Deprecated `Graph.compute()` and `GraphComputer.submit()` in favor of `GraphComputer.submit(Graph)`.
* Updated Docker build scripts to include Python dependencies (NOTE: users should remove any previously generated TinkerPop Docker images).
* Added "attachment requisite" `VertexProperty.element()` and `Property.element()` data in GraphSON serialization.
* Added `Vertex`, `Edge`, `VertexProperty`, and `Property` serializers to Gremlin-Python and exposed tests that use graph object arguments.

TinkerPop 3.2.4 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* Changed behavior of `ElementHelper.areEqual(Property, Property)` to not throw exceptions with `null` arguments.
* Added `GryoVersion` for future flexibility when introducing a new verison of Gryo and moved serializer registrations to it.
* Fixed Gryo serialization of `ConnectiveP` instances.
* Lessened the severity of Gremlin Server logging when it encounters two or more serializers addressing the same mime type.

Created AkkaGremlinPlugin so you can import akka-gremlin into GremlinConsole (and GremlinServer--not sure). The concept of an Actor Address now has to identifies -- the physical location of the actor and the unique (provider specific) guid of the actor. By knowing the physical location and knowing if its local to the sending actor, then detachment/attachment isn't required. Also added TraversalSource.withProcessor(Description). Computer implements Description and now a new Actors implements Description. Both GraphComputer and GraphActors implement a marker interface called Processor. So, g.withProcessor(Actors.of(AkkaGraphActors).partitioner(...)).

-* Bumped to support Spark 2.0.0.
++* Bumped to support Spark 2.0.0 with Scala 2.11.
+ * Added `UnshadedKryoShimService` as the new default serializer model for `SparkGraphComputer`.
+ * `GryoRegistrator` is more efficient than the previous `GryoSerializer` model in `SparkGraphComputer`.
+ * Added support for `IoRegistry` custom serialization in Spark/Giraph and provided a general `hadoop-gremlin` test suite.
* Replaced term `REST` with `HTTP` to remove any confusion as to the design of the API.
* Moved `gremlin-benchmark` under `gremlin-tools` module.
* Added `gremlin-tools` and its submodule `gremlin-coverage`.

^^^^^^^^^^^^^^^^^^
The switch name has changed for installing dependencies. `-i` has been deprecated and replaced by `install`.
+
+ SparkGraphComputer GryoRegistrator
+ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ Historically, `SparkGraphComputer` has used `GryoSerializer` to handle the serialization of objects in Spark. The reason
+ this exists is because TinkerPop uses a shaded version of Kryo and thus, couldn't use the standard `KryoSerializer`-model
+ provided by Spark. However, a "shim model" was created which allows for the shaded and unshaded versions of Kryo to
+ interact with one another. To this end, `KryoSerializer` can now be used with a `GryoRegistrator`. The properties file
+ for a `SparkGraphComputer` now looks as follows:
+
+ ```
+ spark.serializer=org.apache.spark.serializer.KryoSerializer
+ spark.kryo.registrator=org.apache.tinkerpop.gremlin.spark.structure.io.gryo.GryoRegistrator
+ ```
+
+ If the old `GryoSerializer` model is desired, then the properties file should simply look as before:
+
+ ```
+ spark.serializer=org.apache.tinkerpop.gremlin.spark.structure.io.gryo.GryoSerializer
-```

OMG. That was a 3+ hour bug. The bug was not in Actors, but in GroupStep cloning.... So painful. Renamed Actors to GraphActors so its like GraphComputer. Renamed ActorStep to TraversalActorProgramStep so its like TraversalVertexProgramStep. Next up, get rid of GraphComputing and add PushBased as that is the more general categorization. In push-based execution engines, certain steps need to do certain things. What a day -- so much was accomplished and at the same time, what a hellish code-hole nightmare.

Posted by ok...@apache.org.
We now have PartitionInputFormat which allows an Hadoop-based GraphComputer to pull data from any Graph implementation. PartitionInputSplit is basically a wrapper around Partition so that data access is data-local and thus, for distributed Graph databases, it will simply Partition.vertices() and turn them into VertxWritables. I have a test case that have SparkGraphComputer working over TinkerGraph. Pretty neato. Still lots more cleaning and work to do, but this is a good breather point.

* Added `ProcessTraversalStrategy` which is used to get cached strategies associated with a `Processor`.
* Deprecated `Computer` in favor of `GraphComputer.open()`.
* Deprecated `Graph.compute()` and `GraphComputer.submit()` in favor of `GraphComputer.submit(Graph)`.
+* Added `PartitionerInputFormat` which allows `SparkGraphComputer` and `GiraphGraphComputer` to pull data from any `Graph` implementation.
+* Added `PartitionerInputRDD` which allows `SparkGraphComputer` to pull data from any `Graph` implementation.
* Updated Docker build scripts to include Python dependencies (NOTE: users should remove any previously generated TinkerPop Docker images).
* Added "attachment requisite" `VertexProperty.element()` and `Property.element()` data in GraphSON serialization.
* Added `Vertex`, `Edge`, `VertexProperty`, and `Property` serializers to Gremlin-Python and exposed tests that use graph object arguments.

with process.computer interfaces. ActorStep and ActorStrategy are now
generalized to work with Actors interface
Posted by ok...@apache.org.
started on the process.actor interfaces in gremlin-core. Really cool as the naming/model lines up nicely with process.computer interfaces. ActorStep and ActorStrategy are now generalized to work with Actors interface and now live in gremlin-core. Pretty easy.

TinkerPop 3.2.4 (Release Date: NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* `TinkerGraph` Gryo and GraphSON deserialization is now configured to use multi-properties.
* Changed behavior of `ElementHelper.areEqual(Property, Property)` to not throw exceptions with `null` arguments.
* Added `GryoVersion` for future flexibility when introducing a new verison of Gryo and moved serializer registrations to it.
* Fixed Gryo serialization of `ConnectiveP` instances.

+TinkerGraph Deserialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A TinkerGraph deserialized from Gryo or GraphSON is now configured with multi-properties enabled. This change allows
+TinkerGraphs returned from Gremlin Server to properly return multi-properties, which was a problem seen when
+subgraphing a graph that contained properties with a setting other than `Cardinality.single`.
+
+This change could be considered breaking in the odd chance that a TinkerGraph returned from Gremlin Server was later
+mutated, because calls to `property(k,v)` would default to `Cardinality.list` instead of `Cardinality.single`. In the
+event that this is a problem, simple change calls to `property(k,v)` to `property(Cardinality.single,k,v)` and
+explicitly set the `Cardinality`.
+
+See: link:https://issues.apache.org/jira/browse/TINKERPOP-1587[TINKERPOP-1587]

Posted by ok...@apache.org.
added Pushing and Distributing which are currently the two constructs of GraphComputing. GraphComputing is now deprecated with its corresponding methods calling the respective Pushing/Distributing methods. Pushing means the step is using push-based semantics. Distributing means that the step must be aware of whether it is executing in a master or worker traversal. Came up with a much cleaner way to configure these that doesn't rely on using VerificationStrategies and step-by-step setting. In short, once on a master or worker machine, configure yourself accordingly. Duh.

we now have a full generalized process/actor interface system where akka-gremlin/ implements those interfaces. Next, we have ActorProgram with TraversalActorProgram exectuing a traversal. This is identical in form to GraphComputer where people can submit arbitrary ActorPrograms. This is really clean and consistent with our other work.
