A developer has written an application that writes data to Amazon DynamoDB. The DynamoDB table has been configured to use conditional writes. During peak usage times, writes are failing due to a ConditionalCheckFailedException error. How can the developer increase the application's reliability when multiple clients are attempting to write to the same record?
A) Write the data to an Amazon SNS topic.
B) Increase the amount of write capacity for the table to anticipate short-term spikes or bursts in write operations.
C) Implement a caching solution, such as DynamoDB Accelerator or Amazon ElastiCache.
D) Implement error retries and exponential backoff with jitter.
