@inverted-capital This is something we are actively working on in simplifying and offering this through a single consistency header that can then be used for PUT, GET, LIST, and DELETE operations, offering strong consistency in cases where it is needed. I’m optimistic that we’ll have this ready within a week. To answer your original question, the CAS header that you’re using won’t be sufficient for deletes, which is why we’re streamlining it to just have one header.
