Data engineering·Moving data out of the source
you dumped the source table into the warehouse untouched and did all the shaping afterwards, in SQL, where everyone could read it.
ELT
Also calledextract load transform
Extract from the source, load it raw, then transform inside the warehouse itself. Cheap elastic warehouse compute is what made this the default: the transform is now SQL in version control that any analyst can read, and the raw landing tables are still there when the definition changes. The bill moves with the work — you are now storing everything and paying to re-read it — which is why ELT shops end up caring about partitioning and incremental models far earlier than ETL shops did.
