cayley v0.6.1 Release NotesRelease Date: 2017-04-12 // about 3 years ago
🚀 This release marks community build number three. It includes all the pending features that can be merged before v0.7, which will be a major release to introduce Reification, and may cause breaking changes.
🚀 The storage format was not changed for this release. Existing databases should work properly without any migration needed.
👍 Cayley now supports multiple SQL flavors, including MySQL and CockroachDB.
🚀 This release introduces an experimental GraphQL implementation. Note that it only shares a similar syntax and does not support schema yet. It's a preview feature, so the implementation or API may change in following releases.
⚡️ The import and export formatter system is now modular and can be easily extended. Cayley now supports JSON-LD, Graphviz (aka DOT; export only) and custom binary formats for better import speed. The HTTP API was updated (v2) to support the new formatter system and allows for the streaming of large amounts of data in single request.
The recursive iterator is finally available via the Go path library and Gizmo. It allows traversal of a path recursively to potentially unlimited depth.
A new Schema library was implemented to allow developers to save and load complex Go objects with a single method call.
- 👌 Support for MySQL and CockroachDB.
- Gizmo query language with faster ES5.1-complaint VM (supersedes Gremlin).
- Experimental GraphQL-like query language.
- Modular import/export formats system.
- 👌 Support for JSON-LD, Graphviz (DOT) and Cayley-specific binary format.
- 🐎 HTTP API v2 with better import/export performance for large data files.
- 👍 Recursive iterator support (FollowRecursive).
- Schema lib (aka ORM or Object Persistence Layer).
- IRI prefix registration.
