TinkerPop3 CHANGELOG

TinkerPop 3.4.0 (Avant-Gremlin Construction #3 for Theremin and Flowers)

TinkerPop 3.4.0 (Release Date: January 2, 2019)

This release also includes changes from 3.3.3.

• Changed Python "bindings" to use an actual Bindings object rather than a 2-tuple.

• Improved the Gremlin.NET driver: It now uses request pipelining and its ConnectionPool has a fixed size.

• Implemented IndexStep which allows to transform local collections into indexed collections or maps.

• Made valueMap() aware of by and with modulators and deprecated valueMap(boolean) overloads.

• Use Compare.eq in Contains predicates to ensure the same filter behavior for numeric values.

• Added OptionsStrategy to allow traversals to take arbitrary traversal-wide configurations.

• Added text predicates.

• Added ReferenceElementStrategy to auto-detach elements to "reference" from a traversal.

• Added initial release of the GraphBinary serialization format with Java support.

• Allowed ImportCustomizer to accept fields.

• Removed groovy-sql dependency.

• Modified Mutating steps so that they are no longer marked as final.

• Rewrote ConnectiveStrategy to support an arbitrary number of infix notations in a single traversal.

• GraphSON `MessageSerializer`s will automatically register the GremlinServerModule to a provided GraphSONMapper.

• Removed support for -i option in Gremlin Server which was previously deprecated.

• Implemented ShortestPathVertexProgram and the shortestPath() step.

• AbstractGraphProvider uses g.io() for loading test data.

• Added the io() start step and read() and write() termination steps to the Gremlin language.

• Added GraphFeatures.supportsIoRead() and GraphFeatures.supportsIoWrite().

• Deprecated Graph.io() and related infrastructure.

• GraphMLReader better handles edge and vertex properties with the same name.

• Maintained order of annotations in metrics returned from profile()-step.

• Modified Java and Gremlin.Net ResponseException to include status code and status attributes.

• Modified Python GremlinServerError to include status attributes.

• Modified the return type for IGremlinClient.SubmitAsync() to be a ResultSet rather than an IReadOnlyCollection.

• Deprecated two submit()-related methods on the Java driver Client class.

• Added Client.submit() overloads that accept per-request RequestOptions.

• Replaced Parameterizing.addPropertyMutations() with Configuring.configure().

• Changed interface hierarchy for Parameterizing and Mutating interfaces as they are tightly related.

• Introduced the with(k,v) and with(k) step modulators which can supply configuration options to Configuring steps.

• Allowed GraphProvider to expose a cached Graph.Feature object so that the test suite could re-use them to speed test runs.

• Fixed a bug in ReducingBarrierStep, that returned the provided seed value despite no elements being available.

• Changed the order of select() scopes. The order is now: maps, side-effects, paths.

• Moved TraversalEngine to gremlin-test as it has long been only used in testing infrastructure.

• Nested loop support added allowing repeat() steps to be nested.

• Added idleConnectionTimeout and keepAliveInterval to Gremlin Server that enables a "ping" and auto-close for seemingly dead clients.

• Fixed a bug where lambdas in gremlin-python would trigger a failure if steps using python-only symbols were present (such as as_()).

• Fixed a bug in NumberHelper that led to wrong min/max results if numbers exceeded the Integer limits.

• Delayed setting of the request identifier until RequestMessage construction by the builder.

• ReferenceElement avoids UnsupportedOperationException handling in construction thus improving performance.

• Improved error messaging for failed serialization and deserialization of request/response messages.

• Fixed handling of Direction.BOTH in Messenger implementations to pass the message to the opposite side of the StarGraph.

• Removed hardcoded expectation in metrics serialization test suite as different providers may have different outputs.

• Added IndexedTraverserSet which indexes on the value of a Traverser thus improving performance when used.

• Utilized IndexedTraverserSet in TraversalVertexProgram to avoid extra iteration when doing Vertex lookups.

• Bumped to Netty 4.0.56.Final.

• Fixed .NET GraphSON serialization of P.Within() and P.without() when passing a Collection as an argument.

• Fixed a bug in Gremlin Console which prevented handling of gremlin.sh flags that had an "=" between the flag and its arguments.

• Fixed bug where SparkMessenger was not applying the edgeFunction from MessageScope.

• Fixed a bug in ComputerAwareStep that didn’t handle reset() properly and thus occasionally produced some extra traversers.

• Removed TraversalPredicate class in Gremlin.Net. It is now included in the P class instead.
