Does dynamodb provisioned capacity price consider the data storage?

Solution for Does dynamodb provisioned capacity price consider the data storage?
is Given Below:

I am reading this article about using dynamodb to store time series data https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-time-series.html

it suggests to split the table based on time period. In order to save cost, it suggests to provision low RCU/WCU on old tables.

consider two cases:

  1. I provisioned 1000 RCU and 1000 WCU on one table to include all periods of data.

  2. provision 1000 RCU and 1000 WCU on latest table and provision 5 RCU and 1 WCU on old tables.

In above two cases, the first solution is to use one table, will it be cheaper? Based on the price https://aws.amazon.com/dynamodb/pricing/provisioned/ it only charges based on RCU and WCU. This means I have to pay extra 5 RCU and 1 WCU if I choose the second solution. And the cost will increase if I have more than one old tables.

Am I understand correct?

If yes, can I say create table per time-period will increase the cost?
