A design request says uploads should be instant but does not separate transfer time from extraction completion.
Estimated field mix
The first sketch lets the API parse uploaded documents and write arbitrary worker status into the upload row.
Estimated field mix
The team is choosing whether large document bytes should pass through the API or go directly to controlled object storage.
Estimated field mix
A retry currently moves a completed document back to processing because delivery events are mistaken for authoritative transitions.
Estimated field mix
An accepted upload can be stranded if the API commits metadata and crashes before calling the processing provider.
Estimated field mix
A provider times out after accepting work; blindly retrying may launch duplicate expensive processing.
Estimated field mix
Product wants frequent status updates, but the proposal polls the external parser on every customer request.
Estimated field mix
The design has no answer for how long a backlog takes to drain after the parser is unavailable for an hour.
Estimated field mix
Stakeholders disagree about queueing because one alternative is evaluated only on its happy path.
Estimated field mix
An existing local prototype parses in its request handler; the team needs an incremental path to the agreed boundary.
Estimated field mix
The regional-read proposal treats a public tracking estimate and an address-change confirmation as equally cacheable.
Estimated field mix
A proposal promises a faster dashboard without separating network time, database time and sequential request dependencies.
