I think [4] has a pretty simple implementation. When a user wants to save to disk, just create a temporary FileStore, and copy all the key-values from the Off-Heap-Store into the FileStore map(s), and the commit and close. This could be built into to the OffHeapStore as a function: public void saveToFile(fileName), and a corresponding loadFromFile(fileName) that does the reverse. But it could just as easily be done by the applilcation programmer instead of being built into the OffHeapStore class. -Adam On Monday, October 17, 2016 at 7:27:43 PM UTC-4, Adam McMahon wrote: > > Hi, > > I am a long time user of H2, but I am now just exploring the MVstore map > api.
