While DAX offers numerous benefits, there are also some challenges to consider:
Consistency Models: DAX is designed for eventually consistent reads. If your application requires strongly consistent reads, you may need to implement additional logic. Cache Misses: If the data is not already cached in DAX, it will fetch it from DynamoDB, which can introduce some latency. Operational Overhead: Although DAX is fully managed, you still need to monitor its performance and handle scaling and failover scenarios.
