Goblin OGM on top of TinkerPop 3

Licensed under the Apache Software License v2

The original Goblin was a TinkerPop 3 ready port of Cody Lee's mogwai, an excellent library that had been developed for use with pre-TinkerPop 3 versions of Titan. We designed Goblin to provide asynchronous programming abstractions that would work using any version of Python 2.7 + with a variety of asynchronous I/O libraries (Tornado, Asyncio, Trollius). While in theory this was great, we found that in our effort to promote compatibility we lost out on many of the features the newer Python versions provide to help developers deal with asynchronous programming. Our code base became large and made heavy use of callbacks, and nearly all methods and functions returned some sort of Future. This created both a clunky user API, and a code base that was difficult to reason about and maintain.

So, we decided to rewrite Goblin from scratch...

Goblin is built directly on top of TinkerPop and allows access to all of the internals. This ensures all the TinkerPop features are available to the end-user. The TinkerPop stack provides several tools which can be used to work with Goblin.

  • Gremlin, a database agnostic query language for Graph Databases.
  • Gremlin Server, a server that provides an interface for executing Gremlin on remote machines.
  • a data-flow framework for splitting, merging, filtering, and transforming of data
  • Graph Computer, a framework for running algorithms against a Graph Database.
  • Support for both OLTP and OLAP engines.
  • TinkerGraph a Graph Database and the reference implementation for TinkerPop.
  • Native Gephi integration for visualizing graphs.
  • Interfaces for most major Graph Compute Engines including Hadoop M/R. Spark, and Giraph.

Goblin also supports any of the many databases compatible with TinkerPop including the following.

Some unique feature provided by the Goblin OGM include:

  • High level asynchronous Object Graph Mapper (OGM)
  • Integration with the official gremlin-python Gremlin Language Variant (GLV) - now provided by aiogremlin
  • Native Python support for asynchronous programing including coroutines, iterators, and context managers as specified in PEP 492
  • Asynchronous Python driver for the Gremlin Server - now provided by aiogremlin
  • Async Graph implementation that produces native Python GLV traversals - now provided by aiogremlin
