Elasto is a cloud storage client project that has been developed across a number of SUSE Hack Weeks.<br /> It currently supports Amazon S3 and Microsoft Azure REST storage protocols, and includes a POSIX like file API.<br /> For Hack Week 12 I plan to extend Elasto in the following ways:

  • Add support for the Ceph RADOS Gateway<br />
    • RADOS Gateway is capable of processing S3 requests, but Elasto is currently hard-coded to use Amazon hosts, and makes certain assumptions about request and response formats.<br />
  • Extend the file API, which currently only uses the Azure Blob service backend.<br />
    • Azure File service support should also be implemented.<br />
    • An S3 back-end could also be implemented, with write-at-offset constraints.<br />
    • Directory handle operations still need to be finished.<br />
  • The project tracker should be moved to off of Google Project Hosting, which will be discontinued.
  • Cleanup and push the cURL->libevent http client conversion changes.

    I completed the following Elasto tasks during Hack Week 12:

    • Moved elastocloud.org from Google code to GitHub
    • Added a new readdir API call for account, container and blob enumeration
    • Azure lease handling improvements
      • Added support container level leasing
      • Lease status processing during during blob / container enumeration
    • Fixed a few bugs in the libevent based connection and message dispatch code-path
    • Added support for account and container fstat requests
    • Added a location constraint parameter for creations
    • Implemented an Amazon S3 Elasto libfile back-end
    • Improved cmocka test suite coverage
    • Added support for cloud_proto://hostname/path/to/object URIs
      • This serves as the basis for Ceph RADOS gateway support, e.g. s3://radosgw_host/bucket/object
      • Changes to fully propagate these URIs though the client and request layer still need to be cleaned up and pushed
