Hi Vitor, you can use FST with http://prevayler.org/old_wiki/ThereCanOnlyBeOne.html , to avoid issues with class versioning. A limitation from the FST home page: "reads/writes to a temporary buffer in memory to speed up things. This might impose a problem when reading/writing huge objects > 100MB". Not clear if he means huge arrays or huge graphs.
