Description

As of #8896, Frontier.Flush() writes tiles serially with no retries. Ideally we should write tiles in parallel, have per-attempt timeouts shorter than the overall context deadline, and do retries. Since tile writing is on the sequencing path, this will strongly influence how long sequencing takes, which in turn influences how frequently we can sequence.

Part of #8738

Research direction

Start at Frontier.Flush and review the context from #8896 and the broader work in #8738. Determine how tile writes currently occur on the sequencing path, then define completion around parallel writes, per-attempt timeouts shorter than the overall deadline, and retries without delaying sequencing unnecessarily.
