Project context
A fictional logistics platform lists shipments for partner dashboards. Offset pagination duplicates records during updates, while unrestricted filters create expensive database queries.
Setup prerequisites
- Create a local shipment dataset with synthetic tenants, equal timestamps, and concurrent update fixtures.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- BAPIPAGE-101 · Define supported shipment filters and their exact semantics
- BAPIPAGE-102 · Validate bounded sort options instead of accepting SQL fragments
- BAPIPAGE-103 · Enforce tenant scope before applying user filters
- BAPIPAGE-104 · Encode opaque cursors bound to the normalized query
- BAPIPAGE-105 · Use keyset traversal for shipments sharing timestamps
- BAPIPAGE-106 · Define how mutable shipment updates affect an active traversal
- BAPIPAGE-107 · Bound total-count work independently of result pagination
- BAPIPAGE-108 · Review query plans for supported high-cardinality filters
- BAPIPAGE-109 · Provide a resumable iterator that stops on cursor expiry
Acceptance criteria
- State ordering, freshness, and traversal guarantees.
- List unsupported snapshot assumptions.
- Show the appropriate restart and bounded export approach.
Implementation constraints
- No legal or financial completeness claims.
Verification to include
- Follow the guide for a changing dashboard list.
- Identify a use case requiring a separate snapshot export.
Deliverables
- Query API usage guide.
Rollout and recovery
Keep examples aligned with implemented consistency behavior.
Value of the work
For the engineer: Practice cursor design, query contracts, and consistency/performance tradeoffs.
For the team: Provide predictable list APIs that remain bounded and preserve tenant scope.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
