Could BLOBs/large varchar be stored externally?
Sep 25, 2010
If an application would be "agreeable" to VoltDB "limitations", but would also require BLOBs/large varchar which would be too expensive to be stored in memory (for example images), how difficult would it be to stored them externally? Either in files or some other type of database. The problem with handling this in the application logic, is that you then get distributed transactions, and I don't think VoltDB support them yet. Having some kind of transparent swap to external storage would simplify the client code.
