How many records can be included in a batch when using the Batch API?

When utilizing the Batch API in Salesforce, you can include up to 10,000 records in a single batch request. This allows for efficient processing of large datasets, minimizing overhead by reducing the number of API calls needed. The design of the Batch API is to handle bulk operations effectively, which is particularly beneficial when dealing with significant volumes of data, as it improves performance and reduces latency compared to making individual requests for each record.

The limit of 10,000 records is set to balance performance and system resource usage, ensuring that the server can process incoming requests without being overwhelmed while still allowing users to perform substantial data manipulations efficiently. Therefore, the choice indicating 10,000 records accurately reflects the operational capacity of the Batch API.
