Читать книгу Data Lakes For Dummies - Alan R. Simon - Страница 25

You load your data into the bronze zone when the data first enters the data lake. First, you extract the data from a source application (the E part of ELT), and then the data is transmitted into the bronze zone in raw form (thus, one of the alternative names for this zone). You don’t correct any errors or otherwise transform or modify the data at all. The original operational data should look identical to the copy of that data now in the bronze zone.

Your catchphrase for loading data into the bronze zone is “the need for speed.” You may be trickling one piece of data at a time or bulk-loading hundreds of gigabytes or even terabytes of data. Your objective is to transmit the data into the data lake environment as quickly as possible. You’ll worry about checking out and refining that data later.
