Blobstore for MongoDB

This is intended to be a simple replacement for binary object storage in MongoDB. GridFS does not play well with transactions, and it looks too much like a file system so using it for generic BLOB storage is usually inconvenient. This Go library provides a simple replacement for it.

Create a blob store using:

store := &blobstore.Store {
   Collection: coll,
}

Make sure indexes are created for the store. This will run once for the lifetime of the store.

store.EnsureIndex(context.Background())

You can simple write to a BLOB with its id. You have to generate an ID yourself:

	err := store.Write(context.Background(), blobID, bytes.NewReader(data))

And read from it:

	rd, err := store.Read(context.Background(), blobID)

You have to close the returned reader. You can close it midway if you are not interested in the whole stream.
