### Fields

When adding new fields, make sure to think about how it will affect the performance and efficiency of your system. Remember these guidelines.

* **Avoid duplicate code**: Ensure that the handlers for different fields do not contain duplicated code. Fields may rely on each other, so organize dependencies logically without causing loops.
* **Reduce record duplication**: Reduce record processing by removing duplicates at the start to avoid unnecessary data retrieval.
* **Manage dependencies wisely**: Ensure your `dependencies` array includes only the fields you need. Extra dependencies can slow down processing and add unnecessary complexity.
* **Use batch API calls**: When working with arrays of records and using `.map()`, it's more efficient to make batch API calls rather than separate requests for each item.
* **Leverage relationships**: Leverage the `dependencies` array to link data whenever possible. This minimizes the need for additional queries.
* **Limit external queries**: Reduce external service queries to minimize performance issues.
* **Consider field quantity**: Think about the impacts of adding more fields to your handler. Extra fields may harm performance.
* **Use emulation cautiously:** Activating fields emulation demands fetching all records individually, leading to increased performance costs that scale linearly with record numbers.
