I recently started noodling with this concept and built a working blob storage
service using node.js and C*. I setup a basic web server using the express web
server where you could POST binary files to the server where they would get
chunked and assigned to a user and bucket, in the spirit of S3. Then when you
retrieved the file with a GET it would reassemble the chunks and push it out.
What was really nice about node.js is I could retrieve all the chunks in
parallel asynchronously. It was just for fun, but we have considered fleshing
it out for use in our organization. Here is the schema I developed:
CREATE TABLE object.users (
name text PRIMARY KEY,
buckets set<text>,
password text
);
CREATE TABLE object.objects (
user text,
bucket text,
name text,
chunks int,
id uuid,
size int,
type text,
PRIMARY KEY ((user, bucket), name)
);
CREATE TABLE object.chunks (
file_id uuid,
num int,
data blob,
PRIMARY KEY (file_id, num)
);
For your purposes you could modify the objects table to keep a revision id or
timeuuid for looking at previous versions. If you want some insight into how
the code worked give me a shout.
