PR Summary

• Enhancements to stored_query.rb

  • The code in app/graphql/api/v2/stored_query.rb now tracks additional key bits of information related to Dossier, String Value, and File fragments for better data transparency and sortability:
    • The type of these fragments (__typename)
    • The time when specific String Value and File fragments were last updated or created (updatedAt, createdAt)
  • The PageInfoFragment now logs the startCursor, improving page navigation and item location in large datasets.

• Improvement in attachment.rb

  • Updates to app/graphql/extensions/attachment.rb ensure better data effectiveness and memory utilization:
    • The after_resolve method now compacts the attachments array after resolution, which means it removes any null or unnecessary values, hence optimizing memory usage.
