Method: projects.locations.reservations.assignments.delete

Deletes a assignment. No expansion will happen.


  • Organization organizationA contains two projects, project1 and project2.
  • Reservation res1 exists and was created previously.
  • assignments.create was used previously to define the following associations between entities and reservations: <organizationA, res1> and <project1, res1>

In this example, deletion of the <organizationA, res1> assignment won't affect the other assignment <project1, res1>. After said deletion, queries from project1 will still use res1 while queries from project2 will switch to use on-demand mode.
