Fantastic presentation from Jon Moore on why Comcast (enterprises?) is
not interested in NoSQL databases:
- it is not for massive scale
- it is not for high performance
- it is not for handling Big Data
- NoSQL databases still carry risks and require more ramp-up and investment
- it is for the distributed nature of NoSQL databases, including multi-data center support
- it is for operational scalability and operational friendliness of NoSQL databases

Darren Wood presentation containing a mix of details on distributed graph databases and graph databases use cases:
According to Darren distributed graph databases characteristics are:
- High performance distributed persistence
- Ability to deal with remote data reads (fast)
- Intelligent local cache of subgraphs
- Distributed navigation processing
- Distributed, multi-source concurrent ingest
- Write modes supporting both strict and eventually consistency
You might want to check Marko Rodrigues’ Graph Databases: more than an introduction for a more complete list of possible graph databases use cases.

From ☞ DBMS2:
eBay sees Hadoop as an interesting tool for certain special purposes:
- eBay likes Hadoop for certain tasks such as image analysis.
- eBay doesn’t like Hadoop for anything that requires data movement, such as a join.
- Similarly, eBay doesn’t like HBase.
But based on reports from Hadoop World it looks like eBay usage of Hadoop is quite wide:
- eBay had a 4 node cluster in 2007, a 28 and a 10 node cluster in 2009, a 500+ nodes cluster in 2010
- 4200 processors, 4.3 PB of data on CentOS 1U 48 GB RAM datanodes.
- production cluster will be 8500 procs, 16PB

Peter Neubauer’s slides on Neo4j use cases in the Telecom market:
In the Telecommunications sector, there are a lot of complex data sets and problems that are well suited for graph models and the use of graph databases like Neo4j. This talk gives just some ideas on where Neo4j currently is used within the TelCo sector.
Some of the Neo4j usecases mentioned:
- call data records analysis
- social graphs
- master data management
- spatial and LBS
- network topology analysis
