title: Will DynamoDB get Materialized Views?
body: <p>I am considering choosing between DynamoDB and AWS Keyspaces.</p>
  <p>My main issue is still with many-to-many relationship in Dynamo. You don't really have too nice options. Either you do adjecency list for immutable data...but in most scenarios data is gonna change. Other way is making 2 db calls which is really not that great. Third option would be to update data all the time which seems also like a big pain in the a**. Also for batch writes it's up to 25 rows I think.</p>
  <p>However Cassandra provides materialized views where at least I don't have  to manage replication on my own. Also I can do 1 DB call to get all I need.</p>
  <p>I am still relatively new to NoSQL databases so I might be missing a lot of stuff.</p>
  <p>Are there plans for Dynamo to add Materialized Views or is there better way to do it?</p>
  <p>In my eyes it seems like a really good feature. It doesn't even have to create new tables, rather references between columns of items to make it autoupdate.</p>
