What is core api and callback api?
In MongoDB, the Core API and Callback API are approaches to handle transactions, enabling operations across multiple documents or collections as a single atomic unit. Here’s an explanation of both and their differences
Core API: The Core API is a lower-level interface for managing MongoDB transactions. It provides explicit control over the transaction lifecycle, requiring developers to:
Start a transaction.
Handle errors manually.
Commit or abort the transaction explicitly.
Callback API: The Callback API is a higher-level abstraction that simplifies transaction management. It automates aspects like retrying on transient errors and handling unknown commit results.
Reduces developer effort by automating retries and commit handling
Recommended for most general use cases to simplify transaction workflows.
Automatically incorporates error-handling logic for TransientTransactionError and UnknownTransactionCommmitResult.
