#21: OpenStack Swift On File

Swift on File enables the swift object store hosted over clustered file system to have file as well as object access for the same data. Such multi protocol access enables various use-cases where data can be ingested via object and processed for analytics over file protocols (SMB/NFS/POSIX). In another manifestation, data can be accessed or shared by the user interchangeable via different protocols enabling user data sync n share across protocols. For some of these use-cases, there is a strong need to have common User Identity management across object and file protocols so that one can leverage the underlying common file system features like quota management per user or group, per user/group placement policies on data or even have common authorisation across file and object . In order to achieve this, the approaches need to ensure that objects created by an user via Swift is associated with the user's user ID (UID) and group ID (GID) which is same when the object is accessed by that user via file protocols like NFS/SMB/POSIX (where typically the ID's are stored in a centrally ID mapping server like Microsoft AD or LDAP). This presentation discusses in detail the various issues and nuances associated with having common ID management across Swift object access and file access and presents an approach to solve them without changes in core Swift code by leveraging powerful SWIFT middleware framework. Learning Objectives: 1) Understanding Openstack SWIFT Object Store and File access challanges, 2) Learning about OpenStack middleware which will help developers on its usage, 3) Learning ID management concepts for File and Object, 4) Learning the different approaches to solve SWIFT on File ID management problem, 5) Learning the algorithm that developers can deploy to have common ID management between object (SWIFT) and FILE.
