Working with JSON and Array data in BigQuery 2.5 | Qwiklabs | Data Engineer Learning path
This lab is an in-depth walkthrough of working with semi-structured data (ingesting JSON, Array data types) inside of BigQuery. Denormalizing your schema into a single table with nested and repeated fields can yield performance improvements, but the SQL syntax for working with array data can be tricky. You will practice loading, querying, troubleshooting, and unnesting various semi-structured datasets.
In this lab, you learn about the following:
Loading semi-structured JSON into BigQuery
Creating and querying arrays
Creating and querying structs
Querying nested and repeated fields
