Lineage
Data lineage is the process of visualizing and understanding the flow of data within your data lake. Lineage is critical for data engineers and analysts to understand how data is processed and transformed within the data lake. This section covers the tools Glue provides in regard to lineage.
Glue DataBrew
Glue DataBrew (https://aws.amazon.com/glue/features/databrew/) is a serverless data lineage tool integrated within the AWS Glue ecosystem. DataBrew provides a visual and interactive way of visualizing, transforming, and automating data processing within a Glue data lake.
There are a few key components of DataBrew, as outlined here:
- Datasets: In order to work with data in DataBrew, it must be registered as a dataset. This can be an S3 location, a JDBC database, or a Glue table.
- Projects: A project is a visualization environment that loads a sample of a dataset and allows you to apply transformations and see their results live. Once the user is happy with...
