CNAME: CNAME records can be used to alias one name to another. CNAME stands for Canonical Name.

...

• Plugins loading in editors & packing as part of ECAR.

• Generation of pre-signed URL used by Editors

• ECAR files will be having absolute paths (Need discussion on how to solve)

• Data stored in the DB’s

  streamingUrl

  • downloadUrl

  • variants

  ----------------

  • previewUrl

  • appIcon

  • posterImage

  • artifactUrl

  • toc_url

  • thumbnail

  • assetMap

...

Don’t store the absolute paths in the DB’s. Always store the path with CNAME as prefix.

example:

https://store.diksha.gov.inin/tpntp-content-production/content/assets/do_31329674183946240014126/a-boy-animation-1.mp4

Configure the service with CNAME value as shown below

...

The list of CNAME_properties can be configured by any adopters as per their schema properties.

Challenges:

...

• We can handle only CNAME as part of this scope. Any domain name changes requires data migration as the DB stores the full path with CNAME+Domain.
  Note: This can be generalised by handling the CNAME+Domain on service side while sending the responses by storing only relative paths in the DB.

• ECAR is packaged with CNAME values. So any domain change required data migration by republishing the ECAR’s(Content republish).

• StreamingUrl will required the data migration as it is specific to CSP providers. This may requires regeneration of all streaming URL’s with new CSP provider.
