XDGBench: 3rd party benchmark results against graph databases by Luca Garulli.
From the post:
Toyotaro Suzumura and Miyuru Dayarathna from the Department of Computer Science of the Tokyo Institute of Technology and IBM Research published an interesting research about a benchmark between Graph Databases in the Clouds called:
“XGDBench: A Benchmarking Platform for Graph Stores in Exascale Clouds”
This research conducts a performance evaluation of four famous graph data stores AllegroGraph, Fuseki, Neo4j, an OrientDB using XGDBench on Tsubame 2.0 HPC cloud environment. XGDBench is an extension of famous Yahoo! Cloud Serving Benchmark (YCSB).
OrientDB is the faster Graph Database among the 4 products tested. In particular OrientDB is about 10x faster (!) than Neo4j in all the tests.
Look at the Presentation (25 slides) and Research PDF.
Researchers are free to pick any software packages for comparison but the selection here struck me as odd before reading a comment on the original post asking for ObjectivityDB be added to the comparison.
For that matter, where are GraphChi, Infinite Graph, Dex, Titan, FlockDB? Just to call a few of the other potential candidates out.
Will be interesting when a non-winner on such a benchmark cites it for the proposition that easy of use, reliability, lower TOC outweighs brute speed in a benchmark test.

A Comparison of 7 Graph Databases by Alex Popescu.
Alex links to a graphic from InfiniteGraph that compares Infinite Graph, Neo4j, AllegroGraph, Titan, FlockDB, Dex and OrientDB.
The graphic is nearly unreadable so Alex embeds and points to a GoogleDoc spreadsheet by Peter Karussell that you will find easier to view.
Thanks Alex and Peter!

Gephi Blueprints plugin by David Suvee.
From the homepage:
The Gephi Blueprints plugin allows a user to import graph-data from any graph database that implements the Tinkerpop Blueprints generic graph API. Out of the box, the plugin provides support for TinkerGraph, Neo4j, OrientDB, Dex and RexterGraph. Additionally, it also provides support for the FluxGraph temporal graph database.
Excellent!
Not to mention having a short list of interesting graph software to boot!

Persistent Graphs with OrientDB by Luca Molino.
Description:
This talk will present OrientDB open source project and its capability to handle persistent graphs in different ways. OrientDB presentation Java Graph Native API SQL+graph extensions HTTP API Blueprints API Gremlin usage Console tool Studio web tool.
Having the slides would make this presentation much easier to follow.
The phrase “persistent graph” is used in this and other presentations with no readily apparent definition.
Wikipedia was up today so I checked the term Persistent Data Structure, but nothing in that article had anything in common (other than data, data structure) with the presentation.
I suspect that “persistent graph” is being used to indicate that data is being stored and different queries can be run against the data (without changing the data). I am not sure that merits an undefined term.

NuvolaBase.com
I was surprised to see this at the end of the OrientDB slides on the multi-master architecture, “the first graph database on the Cloud,” but I am used to odd things in slide decks. 
From the FAQ:
What is the technology behind NuvolaBase?
NuvolaBase is a cloud of several OrientDB servers deployed in multiple data centers around the globe.
What is the architecture of your cloud?
The cloud is based on multiple servers in different server farms around the globe. This guarantee low latency and high availability. Today we have three server farms, two in Europe and one in USA. We’ve future plans to expand the cloud in China and South America.
Oh, did I mention that during the beta test is it free?

Pilot
From the readme file:
Pilot is a graph database operator that allows you to perform common application-level operations on graph databases without delving into the details of their implementation or requiring knowledge of the component technologies.
Pilot aims to support graph databases conforming to the property graph model. Pilot employs technologies from the Tinkerpop stack — specifically Blueprints and Gremlin — for general access and manipulation of the underlying graph database, but also uses native graph database APIs to further optimize performance for certain operations. In addition, Pilot also handles multithreading and transaction management, while keeping all of these abstracted away from the calling application. As such, Pilot is ideally suited for use in concurrent web applications.
- Supported graph database providers:
- OrientDB
- Neo4j
-
Tinkergraph (the Blueprints in-memory reference implementation)
- (others may be added in future if there is demand)
- Some of the functionality currently supported by Pilot include:
- Get edges between given vertices
- Get neighbors of a given vertex
- Retrieving vertices corresponding to some properties (see Property Graph Model)
- Transaction management
- Thread synchronization for multithreaded access
- Large commit optimization
- Application profiling
Graph databases aren’t a new idea. I don’t have the reference at hand but once ran across a relational database that was implemented as a hypergraph. It may be that computing power has finally gotten to the point that graph databases, or at least their capabilities, will be the common expectation.

OrientDB version 1.0rc6
From the post:
Hi all,
after some delays the new release is between us: OrientDB 1.0rc6. This is supposed to be the latest SNAPSHOT before official the 1.0.
Before to go in deep with this release I’d like to report you the chance to hack all together against OrientDB & Graph stuff at the next Berlin GraphDB Dojo event: http://www.graph-database.org/2011/09/28/call-for-participations-berlin-dojo/.
Direct download links
OrientDB embedded and server: http://code.google.com/p/orient/downloads/detail?name=orientdb-1.0rc6.zip
OrientDB Graph(ed): http://code.google.com/p/orient/downloads/detail?name=orientdb-graphed-1.0rc6.zip
List of changes
- SQL engine: improved link navigation (issue 230)
- Console: new “list databases” command (issue 389)
- Index: supported composite indexes (issue 405), indexing of collections (issue 554)
- JPA: supported @Embedded (issue 436) and @Transient annotations
- Object Database: Disable/Enable lazy loading (issue 563)
- Server: new Automatic backup task (issue 556), now installable as Windows Service (issue 61)
- Client: Load balancing in clustered configuration (issue 557)
- 34 issues closed
This looks great!
I want to call your attention to the composite indexes issue (issue 405). An index built across multiple fields. Hmmm, composite identifiers anyone?

I don’t have a link (yet) but @lgarulli reports that OrientDB’s new index has a measured growth factor of 0,000006 per entry stored.
Will update when more information becomes available.
See OrientDB.
Although for the new index you will need the sources I suspect: OrientDB sources.
Lars suggested the correction when this post appeared but I never quite got around to changing it. Preserved the original as I dislike content that changes under foot.

OrientDB v1.0rc4
In case you haven’t read about OrientDB before:
OrientDB is a new Open Source NoSQL DBMS born with the best features of all the others. It’s written in Java and it’s amazing fast: can store up to 150,000 records per second on common hardware. Even if it’s Document based database the relationships are managed as in Graph Databases with direct connections among records. You can travere entire or part of trees and graphs of records in few milliseconds. Supports schema-less, schema-full and schema-mixed modes. Has a strong security profiling system based on user and roles and support the SQL between the query languages. Thank to the SQL layer it’s straightforward to use it for people skilled in Relational world.
The list of latest changes.
From the latest announcement:
Please help OrientDB to be more famous by writing a short review in your Blog, Magazines and Mailing Lists. The magic formula is: More users = More test = More stable = More support (drivers, plugins, etc).
That’s clear enough!

bulbflow: a Python framework for the graph era
From the Overview:
Bulbs is an open-source Python persistence framework for graph databases and the first piece of a larger Web-development toolkit that will be released in the upcoming weeks.
It’s like an ORM for graphs, but instead of SQL, you use the graph-traveral language Gremlin to query the database.
You can use it to connect to any Blueprints-enabled
database, including TinkeGraph, Neo4j, OrientDB, Dex, and OpenRDF (and there is an InfiniteGraph implementation in development).
This means your code is portable because you can to plug into different graph database backends without worrying about vendor lock in.
Bulbs was developed in the process of building Whybase, a startup that will open for preview this fall. Whybase needed a persistence layer to model its complex relationships, and Bulbs is an open-source version of that framework.
You can use Bulbs from within any Python Web-development framework, including Flask, Pyramid, and Django.
Will be watching for future developments!

OrientDB 1.0rc3 – Graph(Ed)
From the webpage:
This is a special edition of OrientDB with these TinkerPop technologies in bundle:
- Blueprints provides a collection of interfaces and implementations to common, complex data structures. In short, Blueprints provides a one stop shop for implemented interfaces to help developers create software without being tied to particular underlying data management systems.
- Gremlin is a Turing-complete, graph-based programming language designed for key/value-pair multi-relational graphs. Gremlin makes use of an XPath-like syntax to support complex graph traversals. This language has application in the areas of graph query, analysis, and manipulation.
- Pipes is a graph-based data flow framework for Java 1.6+. A process graph is composed of a set of process vertices connected to one another by a set of communication edges. Pipes supports the splitting, merging, and transformation of data from input to output.
The graph community just keeps getting stronger.

NoSQL Databases: Why, what and when by Lorenzo Alberton.
When I posted RDBMS in the Social Networks Age I did not anticipate returning the very next day with another slide deck from Lorenzo. But, after viewing this slide deck, I just had to post it.
It is a very good overview of NoSQL databases and their underlying principles, with useful graphics as well (as opposed to the other kind).
I am going to have to study his graphic technique in hopes of applying it to the semantic issues that are at the core of topic maps.

NoSQL Tapes: A filmed compilation of interviews, explanations & case studies
From the email announcement by Tim Anglade:
Late last year, as the NOSQL Summer drew to a close, I got the itch to start another NOSQL community project. So, with the help of vendors Scality and InfiniteGraph, I toured around the world for 77 days to meet and record video interviews with 40+ NOSQL vendors, users and dudes-you-can-trust.
….
My original goals were to attempt to map a comprehensive view of the NOSQL world, its origins, its current trends and potential future. NOSQL knowledge seemed to me to be heavily fragmented and hard to reconcile across projects, vendors & opinions. I wanted to try to foster more sharing in our community and figure out what people thought ‘NOSQL’ meant. As it happens, I ended up learning quite a lot in the process (as I’m sure even seasoned NOSQLers on this list will too).
I’d like to take this opportunity to thank everybody who agreed to participate in this series: 10gen, Basho, Cloudant, CouchOne, FourSquare, Ben Black, RethinkDB, MarkLogic, Cloudera, SimpleGeo, LinkedIn, Membase, Ryan Rawson, Cliff Moon, Gemini Mobile, Furuhashi-san, Luca Garulli, Sergio Bossa, Mathias Meyer, Wooga, Neo4J, Acunu (and a few other special guests I’m keeping under wraps for now); I couldn’t have done it without them and learned by leaps & bounds for every hour I spent with each of them.
I’d also like to thank my two sponsors, Scality & InfiniteGraph, from the bottom of my heart. They were supportive in a way I didn’t think companies could be and let me total control of the shape & content of the project. I’d encourage you to check them out if you haven’t done so already.
As always, I’ll be glad to take any comments or suggestions you may have either by email (tim@nosqltapes.com) or on Twitter (@timanglade).
Simply awesome!

Orient: The Database For The Web
Nice slide deck if you need something for the company CTO.
Perhaps to justify a NOSQL conference or further investigation into NOSQL as an option.
I was deeply amused by slide 19′s claim of “Ø Config.”
Maybe true if I am running it on my laptop during a conference presentation.
A bit more thought required for use in or with a topic map system.
Orient is an impressive bit of software and is likely to be used or encountered by topic mappers.
Questions:
- Uses of OrientDB in library contexts? (3-5 pages, citations/links)
- Download and install OrientDB. How do you evaluate it’s claim of “Ø Config?” (3-5 pages, no citations)
- Extra credit: As librarians you will be asked to evaluate vendor claims about software. Develop a finding aid on software evaluation for librarians faced with that task. (3-5 pages, citations)
