      Description

      Table/chunk deletion can be an extended process as some worker nodes may be temporarily down. We need to define a process and its supporting structures in CSS to allow gradual deletion of individual chunks and full tables.

      Deliverable: a design of a system capable of deleting a distributed table (all chunks, all replicas). It should be possible to create a table with the same name after deletion.

            For the record, discussed at Qserv hangout 4/8, decided: introduce small delay, rely on fast synchronization between czars and CSS

            It's been semi-reviewed by AndyS and Daniel. Fritz, please see how it looks. I'd like to close it next week. Maybe we should talk about the call-backs?
