Description

  • Remove config table
  • Merge xfeature with xfeaturevals table
  • Separate tables for information about current objects and versions:
    - nodes/versions
    - attributes/version_attributes
    - statistics/version_statistics
  • Add account and container to most tables with corresponding indexes
  • Use object UUID as the unique identifier and remove the 'serial' field
