Moving from DataStage to SQL in ETL mode ELT mode with a containerized buffer database
Moving from DataStage to SQL in ETL mode ELT mode with a containerized buffer database Some companies are considering moving away from DataStage, IBM's popular ETL. The reasons are sometimes linked to licensing costs or process maintainability issues. But this shift mainly responds to an increasingly pressing need for performance and scalability : processes managed by historical ETLs (such as DataStage) tend to decline in favor of simple SQL or quasi-SQL processing in modern databases (such as BigQuery, Snowflake, Redshift, etc.), or via lighter ETL processes. It is possible to automate the transition from DataStage to simple SQL or enriched SQL, in ELT mode. However, issues of readability and efficiency of the target database may arise. They can be addressed by parallelizing processes on a third-party container, within modern databases, in ETL mode. We'll explain it to you. Stages 1: Convertin...
