ELT is really 2 steps EL (Extract-Load) and T (Transform). The EL step is also commonly referred to as “replication” where data is extracted from source systems and loaded into a date warehouse, keeping it in raw or as-close-to raw state as possible (View Highlight)
By reimagining Extract-Load as a standalone “data replication” system, we drastically simplify the data movement problem. Now we only really need two things: source credentials and destination credentials. All other decisions can be delegated to the EL system. The job of data replication (aka the “EL” system) is to replicate efficiently, securely, and with high fidelity. (View Highlight)
