Rest API - Rate Limiting and Throttling

How can you combine graceful degradation with caching to improve REST API reliability?

AServe cached partial data when live data fetch fails, with 206 status

BAlways serve cached full data with 200 status, ignoring live failures

CDisable caching to avoid stale data during degradation

DReturn HTTP 500 errors when cache is empty

Step-by-Step Solution

Solution:

Step 1: Understand caching role in graceful degradation
Caching can provide fallback data when live fetch fails, improving reliability.
Step 2: Combine caching with partial success signaling
Serving cached partial data with 206 status informs clients of degraded but usable data.
Final Answer:
Serve cached partial data when live data fetch fails, with 206 status -> Option A
Quick Check:
Caching + 206 status = reliable graceful degradation [OK]

Quick Trick: Use cached partial data with 206 status on failures [OK]
