title: what is the best way to re-create relational database from change log(data lake) in AWS S3?
body: <p>I have stored changelogs(data with information about data) from non-relational schemaless data tables to S3. now I want some structured relational database to query on all the data. So I need to create a database from S3. Now I am confused about what should I do, whether using another S3 or using some traditional database!!!</p>
