beta1 is a major development milestone that has major public API changes,
upgrades Titanium to Titan
0.3, provides a separate Clojure library for
working with any Blueprints-compatible graph database and introduces
a new powerful way of querying graphs: Ogre, a dialect of Gremlin.
Towards Making Clojure A Great Ecosystem For Graph Analysis
When we first introduced Titanium a few months ago, the response was very positive. People liked Titan features, swappable storage and straightforward transaction support.
Back then, Titanium wasn’t the only Titan-related Clojure project on the block. Zack Maril has been working on another project called Hermes for a while. Then Zack released Ogre, a Clojure library for querying Blueprints graphs.
Titanium and Hermes were largely solving the same problem and after
discussing it for some time, we decided to join forces with Zack and
continue working together on
Titanium. Ogre and
Archimedes are now
ClojureWerkz projects and Titanium
1.0.0-beta1 is based on them.
We would like to thank Zack for considering joining the team and all the work he has been doing on Titanium and related Clojure graph libraries.
Moving to Titan 0.3
Titan is still a young project and is actively being worked on. In version 0.3, Titan introduces several breaking API changes and new features such as
- Full text search (indexing)
- Better caching layer
- Lots of optimizations
- Properties on vertices can have properties on them which is very useful for version, timestamping, etc
Titanium closely follows these developments and
1.0.0-beta1 is based on Titan
0.3. Not all
new Titan features are available in Titanium
1.0.0-beta1 but it won’t take long.
1.0.0-beta1 includes a major documentation overhaul
to adapt to the Titan 0.3 changes and separation into multiple libraries.
In addition, Ogre documentation site is now also live
and uses our standard documentation toolchain.
It’s not a ClojureWerkz project if it is not documented well!
Changes between Titanium 1.0.0-alpha2 and 1.0.0-beta1
Archimedes For Working With Blueprints Graphs
Titanium now relies a separate library called Archimedes for graph operations on any Blueprints-compatible graph database.
Ogre For Graph Querying
Titanium depends on Ogre, a powerful Clojure library for querying Blueprints-compatible graphs (a dialect of the Gremlin query language).
clojurewerkz.titanium.gpipe query DSL.
Titan Types Support
In Titan, edge and vertex properties can have custom types. Titanium now supports said custom types.
The documentation guide above provides more information.
Titanium change log is available on GitHub.
