When using eventually consistent reads in DynamoDB, how many reads does each item up to 4 KB count as?

When using eventually consistent reads in DynamoDB, each item that is up to 4 KB in size counts as one read. However, if the item exceeds 4 KB, it will count as an additional read for every 4 KB increment. For example, if an item is 5 KB in size, it actually counts as two reads: one for the first 4 KB and another for the additional 1 KB.

Since the answer provided suggests that each item up to 4 KB counts as two reads, this is not correct. An item of up to 4 KB will be counted as one read when it is accessed with eventually consistent reads. If the item size were more than 4 KB, then it would count as additional reads based on the total size divided by 4 KB increments, rounding up if necessary.

This understanding is crucial when designing applications that interact with DynamoDB, as it directly affects the read capacity units consumed and therefore the cost associated with reading data. In scenarios where optimization and cost management are critical, having a clear grasp of how data size translates to read units can significantly influence design decisions.
