Hi all, have given one more push to my DS clone [0] and have reached the point where it is plug'n'play compatible with the old one except in the two following aspects:
1.- has no support for removable devices, 2.- all metadata properties are just strings. Regarding 1, I really hope we move that stuff out from the DS, because supporting multiple backends adds a lot of complexity and puts at risk our main use case: robust journal support in NAND. I don't think that we have the resources to do this correctly in the short or medium term. About 2, this DS lets activities specify their own metadata properties, but as we don't have namespaces, one activity may add one property in one format and another activity specify the same property as another format. In which format should the DS return those properties in the future? I would like to let activities themselves deal with decoding the values, so that's why to the DS metadata values are opaque byte arrays. I hope this DS will be more maintainable, faster, more robust and prepare the landing of some long needed features. I have written a bit about the goals and some design aspects in [1], I would appreciate comments and questions. I'm pretty sure that I have made some choices that are not the best ones and there will be better alternatives that aren't a big amount of work. I'll be more than happy in rewriting whatever is needed to accommodate improvements, so just shoot. Just remember that this is something that needs to land in the next release and that we cannot break everything else.
