Migrating Amazon Redshift Users to BigQuery

(1 day)

 

In this course, you will learn how to translate various concepts in Amazon Redshift to the analogous concepts in BigQuery. You will learn how the high-level architectures of Amazon Redshift and BigQuery compare, understand differences in how to configure datasets and tables, map data types in Amazon Redshift to data types in BigQuery, understand schema mapping from Amazon Redshift to BigQuery, optimize your new schemas in BigQuery, and do a high-level comparison of SQL dialects in Amazon Redshift and BigQuery.

Course Objectives

  • Comparing architecture and provisioning of resources in Amazon Redshift and BigQuery
  • Configuring datasets and tables in BigQuery
  • Mapping data types in Amazon Redshift to data types in BigQuery
