If two or more clients try to store an object with the same name at the same time, what happens depends on whether versioning is enabled for the target bucket:

  • If versioning is enabled, HCP creates one version of the object for each PUT request. The versions are numbered in the order in which HCP received the requests, regardless of the order in which HCP finished processing the requests.
  • If versioning is disabled and the bucket doesn’t already contain an object with the specified name, HCP creates the object for the first PUT request. In response to each subsequent PUT request, HCP returns a 409 (Conflict) status code and does not create an object. This happens regardless of whether HCP has finished processing the first request.
