Summary
In this chapter, we looked at how data federation helps organizations quickly fetch data using a single pane of glass from multiple heterogeneous source systems.
We looked at how different connectors in Amazon Athena allow for a quick and easy way to join datasets from other sources. Athena’s connectors make it a seamless and transparent user experience where reports can be created just by writing SQL statements inside Athena, to join datasets from the underlying data stores.
We also looked at how Amazon Redshift can assist in federated queries, by fetching data stored in ODS systems such as MySQL and PostgreSQL. A use case that typically gets solved by this mechanism is querying live operational data that’s constantly getting updated in the ODS.
The next chapter is critical in our modern data platform journey as we will discuss everything about predictive analytics and how it helps organizations think big with their data.
