Paginate Nimble API results with offset and limit to avoid timeouts

The problem with pulling everything at once

Requesting a full Nimble data set in a single call risks timeouts, memory pressure on the client, and rate limit errors. The useful takeaway is to pull in bounded batches using offset and limit, with a stable sort key, and stop when a batch returns fewer items than the limit.

This draft assumes Nimble API v1 supports offset/limit pagination on list endpoints. Verify current documentation before use; pagination semantics change between versions.

Desired outcome

Reliably retrieve a complete, non-duplicated result set in pages of a fixed size, with the ability to resume after an interruption without re-fetching data.

Prerequisites

• An API key with read permission for the resource you are paging, stored securely and not logged.
• Knowledge of a stable, monotonically increasing sort field for the resource, e.g., created_at or id. Offset pagination requires a deterministic order.
• A client environment where you can run HTTP requests and store the last successful offset. Run commands from a secure workstation with network access to the Nimble API base URL.
• Placeholder values for {nimble_api_base}, {api_key}, {resource_path}, {limit}, {offset}, and {sort_field}.

Focused procedure

Choose page size and sort

Pick a limit that balances latency and rate limits. Keep the sort order explicit and identical for every request. Changing sort between pages can cause duplicates or gaps.

Request a page

Run the request from a terminal or script with permission to read the API key from environment variables.

curl -s -H "Authorization: Bearer {api_key}" \
  "{nimble_api_base}/{resource_path}?limit={limit}&offset={offset}&sort={sort_field}"

Replace placeholders with actual values. The limit controls the maximum number of items returned, analogous to setMaxResults in ORM pagination. The offset controls the first item to return, analogous to setFirstResult.

Iterate with offset

Increment offset by the number of items actually returned, not by the requested limit. Stop when the returned batch size is less than limit or zero.

• Record the last successful offset and the highest sort key seen.
• If a transient error occurs, retry the same offset with backoff rather than advancing.

Expected checks

• Result size is ≤ limit for each page.
• Items are ordered by the chosen sort field and do not overlap with the previous page.
• Total items accumulated matches the count reported by a separate count endpoint, if available.

A practical verification is to run two consecutive pages and assert that the first item of page N+1 follows the last item of page N in sort order, and that no ids repeat. Do not claim the example was tested.

Limitations and recovery options

Offset based pagination degrades with large offsets because the backend must scan and discard rows. For very large data sets, keyset pagination using a last seen sort value is often preferred.

Pagination may not behave predictably with aggregate filters, distinct queries, or server-side search that reorders results between calls. If filters are applied, ensure they are identical on every request.

Recovery options:

• Resume from the last successfully persisted offset instead of restarting from zero.
• On rate limit responses, pause and retry with exponential backoff.
• If a page returns an unexpected size or out-of-order items, re-request that offset with the same parameters before advancing.

Rollback is not applicable for read-only pagination. If you are writing checkpoints to persistent storage, keep previous checkpoints until the full run is confirmed complete.

Mark for review: current Nimble API endpoint names, parameter names, authentication scheme, and maximum allowed limit need verification against live documentation.
