There's no limit on how big blobs you can store, but performance degrades with bigger blobs. The degradation isn't necessarily gracefully though, since there aren't really much thought or time spent on handling such big properties. I've written apps which stores very long strings (at least several hundred characters each) and it worked quite well. > -----Original Message----- > From: user-boun...@lists.neo4j.org [mailto:user-boun...@lists.neo4j.org] On > Behalf Of Mattias Persson > Sent: Tuesday, June 22, 2010 8:40 AM > To: Neo4j user discussions > Subject: Re: [Neo4j] Store binary data with byte [] > > 2010/6/22 Rick Bullotta <rick.bullo...@burningskysoftware.com> > >> Same question here (since we're storing blobs in Neo today).
