Moving from DataStage to SQL in ETL mode ELT mode with a containerized buffer database
Migrating from DataStage to SQL using ETL , or with a containerized buffer database Some companies are considering leaving DataStage, IBM's famous ETL. The reasons are sometimes related to licensing costs or process maintainability issues. But this shift primarily responds to an increasingly pressing need for performance and scalability : processes managed by legacy ETL tools (such as DataStage) are tending to decline in favor of processing using simple SQL or quasi-SQL 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 rich SQL, in ELT mode. However, issues regarding the readability and efficiency of the target database may arise. These can be addressed by parallelizing processes on a third-party container within modern databases, using ETL mode. We'll expla...
