[SAA + SAP] 09. DynamoDB

  • S3 is not good at searching object
  • We can use DynamoDB to save the metadata of S3 object
  • Then do the search in DyanmoDB

  • If you need to get data directly from DynamoDB, DAX is good for that
  • If you need to perform some calucation which needs quite a bit time to complete, then save the result in ElasticCache, next time can fetch result directly from ElasticCache instead of doing calcuation in DAX or DyanmoDB again.
