The StructType and StructField classes in PySpark are used to define the schema to the DataFrame and create complex columns such as nested struct, array, and map columns. StructType is a collection of StructField objects that determines column name, column data type, field nullability, and metadata. appName('ProjectPro').getOrCreate()

A data catalog is a constantly updated inventory of the universe of data assets within an organization. It uses metadata to create a picture of the data, as well as the relationships between data assets of diverse sources, and the processing that takes place as data moves through systems.

This could just as easily have been Snowflake or Redshift, but I chose BigQuery because one of my data sources is already there as a public dataset. dbt seeds data from offline sources and performs necessary transformations on data after it's been loaded into BigQuery.

It can be challenging when a team is expected to take full responsibility for a key data product when there are no guarantees around the upstream data quality. Without clear management of each transformation step stretching back to source systems, teams may be unwilling to bear the responsibility of contracts.

Since they share most parts of the user journey, it was natural to explore if the Apps could benefit from a system based on Entities and Renderers, too. We want to avoid unwanted data coupling and allow Renderers to be reused in other contexts with minimal risks. We knew it would be too much of a stretch for Mosaic fragments.
