Thanks for the info. We're trying to maintain some level of HA/horizontal scaling capabilities for our blob storage as well, so the file system isn't really a practical alternative for us. When in the Amazon cloud, we could use S3, but we're trying to have a consistent approach for on-premise, embedded, and cloud scenarios. I suppose we could incorporate something like CloudDB, MongoDB, but I'm trying to keep in the Java domain if possible. Does anyone have any experience with Jackrabbit?

This paragraph should have been completed: As a general practice I would advice against storing large data values as properties in Neo4j. A few odd ones can be ok, but for storing a lot of large blobs it is better to store that in some other persistance mechanism. For example on the file system.
