Answer 1

To calculate the total partitions needed in DynamoDB, divide the total number of items in the table by the maximum number of items per partition.

Step-by-step explanation:

To calculate the total partitions needed in DynamoDB, you would divide the total number of items in the table by the maximum number of items per partition.

For example:

If you have a table with 1000 items and the maximum number of items per partition is 200, you would divide 1000 by 200 to get 5 partitions.

Calculation:

1000 / 200 = 5 partitions
