Have a TTL on Table Storage rows, so temporary data gets deleted
Say you are storing details about logs / orders / page views. You may not care about them after 2 weeks / 1 month / 1 year.
To save money it would be great to have a job run daily that deletes this data when it is deemed out of data by the system designer.
AWS has this in DynamoDB where you create a column for an expiration date on tables that will accumulate data that might be temporary by nature. When you create a row you populate this column with the timestamp in the future you want this deleted. AWS then runs a job periodically to delete those rows where the expirary date is in the past - you are not charged for data older than the expiry date http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html
