What is the PRIMARY benefit of this action?
Improves legibility and stylistic convention
Takes advantage of runtime environment reuse
Provides better error handling
Creates a new SDK instance for each invocation
Explanations:
Initializing the SDK outside of the Lambda handler function does not primarily improve legibility or stylistic convention. While it may have minor effects on code organization, this is not the main benefit.
Initializing the SDK outside of the Lambda handler takes advantage of the Lambda execution environment reuse, allowing the SDK instance to be reused across multiple invocations. This reduces initialization time and improves performance.
While initializing the SDK outside the handler may allow for centralized error handling in some cases, it does not inherently provide better error handling compared to initializing it within the handler. Error handling is more related to how the code is structured rather than where the SDK is initialized.
Creating a new SDK instance for each invocation is not the benefit of initializing the SDK outside the handler. In fact, initializing it outside allows for reusing the same instance across multiple invocations, thus avoiding unnecessary overhead.
