Your DynamoDB table has approximately 25GB of data and 1000 RCUs. How many partitions can we expect for this table?
The answer is 3 but it marks as correct the "unable to determine with the given information"
The formula for number of partitions is ( readCapacityUnits / 3,000 ) + ( writeCapacityUnits / 1,000 ) = initialPartitions (rounded up)
Also the max size of partition is 10 GB. So for 25 GB it would at least be 3 partitions.
We know RCU but not WCU – so in theory we can say – not enough information to determine.
