As-is
The UserDailycheck table currently contains 3K items.
Most of them are too old to be shown in the user's daily check-in history (that shows the 4 most recent histories).
To-be
Use DynamoDB's TTL feature. This will remove old items without charge for capacities.
I want to remove items that are seven days old.
