Abstract
A blob transaction component is a tiered middleware framework component that facilitates data transactions across arbitrary data blobs in an optimistically consistent manner. The component receives a request to transact data across multiple stored data blobs. For each stored data blob, the component creates a duplicate data blob. The component then creates a record blob that includes a pointer to the duplicate data blob. The stored data blob is then modified by the component to point to the record blob using optimistic locking. The component then creates a new data blob that includes modified data. The component further updates the record blob to include a pointer to the new data blob using optimistic locking. Following locking of the record blob, the stored data blob is updated with the modified data by the component, and the record blob, the duplicate data blob, and the new data blobs are deleted.
