Hi, The MVStore is mainly meant to store data on disk. Off-heap memory (in which case the data is stored in a ByteBuffer that was created using ByteBuffer.allocateDirect) can be used in two places: (a) as a large file cache, and (b) as the main 'storage' (using an in-memory file system). Both is possible, I guess (b) is easier to implement (a new file system implementation).
I'm sorry, I thought it was about making Map<byte[],byte[]> > If the application wants to deal with byte arrays then that's possible of course, but in most cases the application (and the database engine) wants to deal with 'real' Java objects to avoid serialization / deserialization for each operation. The database engine will probably use Map<Long, Record> or Map<Long, Object[]> to store records. It is also possible to use Map<Object, ByteBuffer> to avoid copying data, but I guess that's not the normal use case.
