How Do I Implement Cursor-based Pagination that Survives Mid-sync Failures and Rate-limit Pauses?
Blog post from Prismatic
Cursor-based pagination retrieves large API datasets sequentially through continuation tokens, often avoiding the shifting-record problems of offset pagination, but it does not by itself guarantee consistent snapshots, prevent duplicates, or avoid missed records when data changes during traversal. Reliable integrations must follow each provider’s cursor contract, preserve filters and sort order, use stable unique ordering where available, retry failed requests without advancing progress, process writes idempotently, and save durable checkpoints only after a page is fully processed. Pagination cursors track progress through a result set, whereas incremental-sync watermarks track changes over time, so recurring syncs benefit from bounded time windows, overlapping queries, deduplication, and periodic reconciliation. Systems should also address rate limits, cursor expiration, concurrent runs, partial failures, and monitoring of throughput and checkpoint lag. API providers can improve reliability by offering documented, opaque or protected cursor tokens, keyset-based queries, stable ordering with tie-breakers, clear termination metadata, and explicit constraints on cursor lifetime and query parameters; platforms such as Prismatic support page-level processing and batching but cannot alter the underlying API’s consistency guarantees.
