title: DynamoDB extra table to keep inactive data
body: <p>Does it make sense in DynamoDB to store inactive / expired data in a separate table to cut cost (scans / queries)?</p>
  
  <p>My plan is to have object with 7 day TTL. When item is removed from DynamoDB it will trigger a Lambda that will put removed record to a new table (not frequently scanned / queried). Or it doesn't really make any difference and i should keep everything in one place?</p>
  
  <p>thanks!</p>
