      Description

      The bug

      The big is caused by the incomplete implementation of the feature explained in DM-26101.
      The worker-side ingest service that processes requests over the proprietary binary protocol (BOOST ASIO, Google Protobuf) is not recording contributions in the persistent state of the Replication/System when processing the request. This excludes contributions from being properly handled by the system at the transaction commit time and the catalog publishing time. Other algorithms (see DM-28603) relying on the persistent records for the contributions made during the transactions are also affected by the problem.

      The second improvement is to allow passing back to a client the retry_allowed flag that's meant to indicate if a failed contribution could be retried.

      NOTE: the file contributions will be recorded with file URLs adhering to this scheme https://en.wikipedia.org/wiki/File_URI_scheme

            I don't think I'm capable of understanding the big picture here without a lot more discussion, but the changes look fine. There's one small nit about the language in a comment but otherwise looks
