I think I will need to write my own blobstore, but I do not know from where
to start =(
Do you have any recomendation or links?
The challenge I am working is to write blocks, send it to some cloud and
delete from my filesystem. When I want to read the files I will restore
these blocks from the cloud.
About Swift, I thinks is very specific for openstack, since I am using a
different cloud (private cloud).
About Riak CS I didn't find much information.
