Issue number: #3505

Summary

Changes

This pull request introduces a new method current_keys to the Logger utility. The primary objective of this method is to offer a straightforward approach for retrieving the currently configured keys utilized within the logger. Additionally, it serves to prevent mistakes such as overwriting keys.

User experience

from aws_lambda_powertools import Logger
from aws_lambda_powertools.utilities.typing import LambdaContext

logger = Logger()


@logger.inject_lambda_context
def lambda_handler(event: dict, context: LambdaContext) -> str:
    logger.info("Collecting payment")

    if "order" not in logger.get_current_keys():
        logger.append_keys(order=event.get("order"))

    return "hello world"
