How can you combine caching with asynchronous API calls in Langchain to reduce costs effectively?

AUse async functions with cache.get_or_set to store awaited results

BCache only synchronous calls, async calls cannot be cached

CCall async API twice to ensure cache is updated

DDisable caching for async calls to avoid race conditions

Step-by-Step Solution

Solution:

Step 1: Understand async caching pattern
Async functions can be cached by awaiting results before storing.
Step 2: Use cache.get_or_set with async lambda
Pass async lambda to get_or_set and await result to cache it properly.
Final Answer:
Use async functions with cache.get_or_set to store awaited results -> Option A
Quick Check:
Async caching requires awaiting results [OK]

Quick Trick: Await async calls before caching results [OK]
