    October 15, 2019

    🚀 This patch release fixes a bug shipped in v0.7.6 that assets deprecation warning pops up even though the assets flag is not provided.

  • v0.7.6

    October 14, 2019

    🚀 The long anticipated release brings a lot of bug fixes and some performance improvements, especially for KV backends.

    Highlights

    Backends

    • 🆕 New SQLite backend (#751).
    • KV and NoSQL backends migrated to Hidalgo.
    • 🎉 Initial import to KV backends should be much faster now (#803).

    Query languages

    • A new Order() iterator and corresponding method for Gizmo (#796).
    • Set of changes to Gizmo to make it more Gremlin-compatible (#822, #849, #859).
    • Gizmo can now emit JSON-LD via HTTP API if appropriate Accept header is set (#821).

    🐛 Bug fixes

    • 👀 A lot of bug fixes for queries, backends, etc. See the full changelog for details.

    Go library

  • v0.7.0

    December 24, 2017

    🚀 Release covers nearly 8 months of work, mostly on implementing meta-backends, new query optimizer, performance improvements and bug fixes.

    Note: From now on we plan to release point releases on regular basis to push fixes and new features faster.

    ⬆️ Storage format for backends received an upgrade bringing backward incompatible changes. Check migration guide for more details. It only affects the database format, HTTP API remains backward-compatible.

    🚀 This release defines new internal interfaces (meta-backends) for working with various database kinds. Currently three of them are defined: KV, NoSQL, SQL. Each of them significantly simplifies a process of implementing a new backend, as well as allows us to lower maintenance overhead by sharing most optimizations, read and write paths, etc. This also means that optimization work on one backend will be automatically applied to other backends of the same kind in the future.

    Part of this effort was an implementation of new query representation that we call "shapes". All optimizations like query rewrites and reordering are now done on a generic level, without any backend-specific code. It will allow us to save query stats, make more complex optimizations and even store query templates in the database, or split it to be executed in distributed manner by multiple backends. Since new representation can be manipulated more easily, most backends will now rewrite complex query types into their native query language (SQL, for example).

    Highlights

    • 👍 ElasticSearch support
    • 🆕 New query optimizer (aka query shapes)
    • 🆕 New command line interface
    • KV meta-backend + port of Bolt and LevelDB to it
    • NoSQL meta-backend, + port of Mongo and ElasticSearch to it
    • 🗄 "Raw" value type is deprecated
    • 🔦 Exposed node delete API for HTTP
    • Consistent behavior for all backends on node delete
    • 🆕 New query types in Gizmo: Labels, SaveInPredicates, SaveOutPredicates, see docs
    • 👍 Has traversal now supports value filters
    • FollowRecursive can be limited to a maximal depth
    • 👍 GraphQL now supports quad labels
    • ⚡️ SQL query optimizer improvements
    • SQL backends now has their own names: postgres, mysql, cockroach (no need to specify flavor)
    • 🐎 Significant performance improvements
    • 🐳 Smaller Docker image
    • 💻 Minor UI improvements

    💥 Breaking changes

    • Bolt, LevelDB and Mongo backends were rewritten and database format has changed. Old implementations are still available under bolt1, leveldb1 and mongo1 names. Old backends will be removed in next minor release. c266392
    • SQL table structure has changed 31b0f48, #617
    • 0️⃣ Cayley now ignores duplicated quads by default 9cb0eef
    • 🗄 Gremlin is deprecated and dropped in favor of Gizmo #519
    • Count in gizmo is now a 'final' instead of traversal and returns result #576

    💥 Breaking changes (Go)

    🔀 As always, we expect users to pin a specific Cayley version tag with a dependency manager and sync with following changes in the code:

    • Cayley uses Go version 1.9+
    • Bolt, LevelDB and Mongo backends were rewritten and database format has changed. Old implementations are still available under old paths, but will be dropped in next minor release. Users are encouraged to update imports to kv/bolt, kv/leveldb and nosql/mongo.
    • SQL flavors moved to their own packages and needs to be imported separately (sql/postgres for example). sql backend name will be deprecated in next major release. 48e7946
    • 🗄 "Raw" value type (quad.Raw and quad.MakeRaw) is deprecated and replaced with a helper to preserve at least some compatibility. It's strongly recommended to switch to quad.String or IRI and quad.Make. 41bf496
    • 🏗 Iterator optimizations for backends are mostly disabled. It is recommended to build queries with new graph/shape package and run optimizations on it.
    • ✂ Removed unused methods from QuadStore: Horizon, FixedIterator, Type d994e2a, b63faea, #631
    • ✂ Removed graph.PrimaryKey type d994e2a
    • graph.Value is now type-safe e4ab526
    • ✂ Removed ID and Timestamp fields from graph.Delta - they will be assigned by server 524c8e2
    • 🚚 RemoveNode type changed to quad.Value to match other methods #607
    • 🚚 Quad writers produced by graph.NewWriter and NewRemover now requires Flush to be called a420e62
    • Iterator now accepts context for Next, NextPath and Contains f3e814f
    • 🚚 Describe method was removed from Iterator and replaced by String method on iterator and graph.DescribeIterator b491f41
    • Iterator type is now a string instead of enum and registration is not necessary anymore

  • v0.6.1

    April 12, 2017

    🚀 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.

    🐎 To avoid further confusion, our Gremlin-style query language was renamed to Gizmo to emphasize that it's not fully Gremlin-compliant. We also switched to the Goja JavaScript VM for better performance and ES5.1 support. Error handling was also improved for our query language.

    🚀 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.

    Highlights:

    • 👌 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.
