Abstract
Methods and apparatus for providing consistent data storage in distributed computing systems. A consistent distributed computing file system (consistent DCFS) may be backed by an object storage service that only guarantees eventual consistency, and may leverage a data storage service (e.g., a database service) to store and maintain a file system/directory structure (a consistent DCFS directory) for the consistent DCFS that may be accessed by compute nodes for file/directory information relevant to the data objects in the consistent DCFS, rather than relying on the information maintained by the object storage service. The compute nodes may reference the consistent DCFS directory to, for example, store and retrieve strongly consistent metadata referencing data objects in the consistent DCFS. The compute nodes may, for example, retrieve metadata from consistent DCFS directory to determine whether the object storage service is presenting all of the data that it is supposed to have.
