Summary
In this chapter, we learned about two new databases offered by AWS – Redshift and DocumentDB. We learned that Redshift is a columnar database store based on PostgreSQL that is fully managed by AWS. We also learned how to use Redshift Spectrum to query data directly from S3 without having to import it.
Regarding DocumentDB, we learned about some of the differences between it and DynamoDB, how it is provisioned, and some key areas regarding its performance. We also learned how to deploy a global cluster, which allows us to run read replicas in multiple regions.
In the next chapter, we are going to learn about three more AWS databases: Neptune, Timestream, and Quantum Ledger DB. By doing this, we will build upon the themes and knowledge we've gained in this chapter.
