Release v0.17.0

We are glad to announce a number of new features and improvements to GraphScope, alongside the GraphScope 0.17 release. The updates include new releases for Spark-GraphX support, backend engine enhancement, and frontend APIs. Currently, GraphX Pregel algorithms can be seamlessly executed on GraphScope. A lot of new features have also been officially brought into the interactive engine (GIE), including the syntactic sugar of path expansion and expression, the Gremlin steps of id(), label(), coin() and otherV() etc. and the profiling and benchmarking tools for LDBC BI queries.

We highlight the following improvements included in this release:

1. Spark-GraphX support for GAE:

• Support converting GraphX graph to GraphScope Fragment
• Support wrapping Fragment as GraphX Graph.
• Support running GraphX pregel on GraphScope Analytical engine.

2. New language features and enhancement for GIE:

• The syntactic sugar of path expansion. Now user can write out[in|both]('x..y', 'KNOWS') to support path expansion of at least x (included) times and at most y (excluded) times from a certain node. with() step can be followed to configure the path expansion.
• The syntactic sugar of expression, introduced by expr(), can be used along with the where()-step to enable filtering expression. For example, .where(expr("@.name == \"John\"")) help filter out the current entry that has the name of "John". We have updated the README doc for some instructions.
• Provide LDBC benchmarking for BI queries.

3. Enhancement and dependency refinement of Groot to reduce the size of fat-jar.

4. Feature updates:

• Add from_dict / to_dict option for graph schema.
• Add syntactic sugar of path expansion, expr(), and the Gremlin steps of id(), label(), coin(), TextP.startsWith/endsWith... etc.

Full Changelog: v0.16.0...v0.17.0

Release v0.16.0

We are bringing a number of improvements to GraphScope, alongside the GraphScope 0.16.0 release. This release introduces many new features on backend engines and system stability. We enable Jave SDK of Graph Analytics Engine (GAE) on MacOS, and make a series of enhancements on the graph storage Groot. We completely remove a legacy Graph Interactive Engine (GIE), while officially replacing it with the latest version based on an intermediate representation (IR) layer; in addition, we improve GIE via a couple of optimizations, new language features, and bug fixes. The Graph Learning Engine (GLE) now supports real-time sampling on dynamic graphs. Meanwhile, we start to release a nightly version every day, and you can try it with pip3 install graphscope --pre.

We highlight the following improvements included in this release:

1. Enhancements of the graph storage Groot:

• Support load table from partitioned ODPS table;
• Speed up some popular gremlin queries;
• Use the GAIA engine to support queries;
• A series of deployment enhancements.

2. Enhancements of the GIE GAIA engine:

• Completely replacing the legacy GIE engine with the latest version based on IR;
• Optimizing the logic of lazily fetching properties from the graph store, and implementing a new CSR-based storage for experiment purpose;
• New language features including more grouping functions, more options for group/dedup/orderby keys, etc.

3. Dynamic-Graph-Service (DGS) is introduced in GLE.

• DGS is an online inference service, it supports real-time sampling on dynamic graphs with streaming graph updates.

4. Support Java SDK of GAE for MacOS.

5. Bug fixes:

• Fixes potential pointer leak in IR-core FFI functions;
• Duplicate results while scanning with primary keys;
• Error while accessing a tag that does not exist in the record.
• Fixes failure of running clustering algorithm on the property graph.

Release v0.14.0

We are delighted to present the release of GraphScope v0.14.0. This release is composed of many updates on backend engines and system stability. The new Graph Interactive Engine (GIE), GAIA-IR, has supported more operators for diverse graph queries. Meanwhile, the persistent storage of GraphScope is further enhanced with a series of new functions. In addition, we continuously work on improving the performance of GraphScope, and developer usability.

We highlight the following improvements included in this release:

1. New supported operators in Graph Interactive Engine (GIE)

• Support valueMap operator to fetch all properties of vertices in the GAIA engine.
• Enable string oid type support for the GIE GAIA engine.
• Support index query for the GAIA engine.

2. More functions on persistent storage of GraphScope

• Support loading dataset from the OSS.
• Enable local GC for the Groot storage.

3. Bug fixes and other enhancements

• Upgrade the NetworkX version from 2.6 to 2.8.
• A new algorithm named voterank has supported in the analytical engine.
• Fix some problems in the property cache of GIE GAIA IR-Core.
• Support to return an empty map if no property in valueMap operation.

Release v0.12.0

The GraphScope v0.12.0 release is a major update on many aspects of the project including backend engines, APIs, and system stability. It introduces an intermediate representation (IR) layer into the graph interactive engine (GIE) GAIA, to decouple query languages from query execution engines. Meanwhile, this release supports Giraph APIs to allow Giraph apps running on the Graph Analytics Engine (GAE) of GraphScope.

We highlight the following improvements included in this release:

1. Introduce IR layer into GAIA:

• A completely redesigned IR layer to decouple the query language dependency, and further for query optimizations.
• Define the supported Gremlin's grammar via Antlr.
• Support match step in Gremlin, for graph pattern matching.

2. Add Giraph APIs to GAE:

• Support to load graphs with Giraph Formats, e.g., graph = sess.load_from(vertices="p2p-31.v", vformat="giraph:com.example.vformat",edges="p2p-31.e", eformat="giraph:com.example.vformat")
• Support Giraph APIs on GraphScope, and all algorithms implemented towards the original Giraph APIs can run on GraphScope without modifications. For example, to load Giraph app SSSP, users can just invoke giraph_sssp = load_app(algo="giraph:com.alibaba.graphscope.example.giraph.SSSP")
• Users now can add jars by sess.add_lib interface.

3. Bug Fixes or other enhancements:

• Correct the lifecycle management of loaded graphs within a session.
• Make the graphlearn and tensorflow related logs more user-friendly.
• Fix readwrite failed on GraphScope Networkx module.
• Enable to connect to the existed ETCD cluster in GraphScope.
• Support to launch GraphScope on K8s from an inner-pod environment.

Release v0.11.0

We are glad to announce a number of new features and improvements to GraphScope, alongside the GraphScope v0.11.0 release. This major release introduces mutable graphs into GraphScope, and adds GPU supports for the graph analytics engine (GAE). It also focuses on user-friendly improvements, code quality, and a series of bug fixes.

We highlight the following improvements included in this release:

Supporting mutable graphs:

• Providing a set of interfaces (e.g., add_vertex, add_edge and update_vertex) to modify the topology of an existing graph.
• Adopting existing apps to mutable graphs.

Accelerating graph analytics apps with GPUs:

• Adding new fragment, worker, message_manager and apps to utilize GPUs to process graph analytics tasks faster.
• On top of these new infrastructures, 6 example algorithms (BFS, WCC, SSSP, PR, CDLP, LCC) are implemented.

Optimizations and enhancements:

• Stream grpc request(response) to support loading graph(fetching result) from(to) numpy/pandas more than 2GB.
• Accelerating manipulation of graph topology by replacing folly::dynamic with rapidjson::value.
