Precise item size for list and map in Dynamodb












0















According to https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/CapacityUnitCalculations.html, the size of a List or Map is (length of attribute name) + sum (size of nested elements) + (3 bytes). The size of an empty List or Map is (length of attribute name) + (3 bytes).



I am curious about the size of the delimiter. In JSON expression, the delimiter of list is , and for map the KV delimiter is : and node delimiter is :. Will these delimiters cost Dynamodb storage space?



How does Dynamodb actually store these nested data type?
