Extract and Load Architecture
1. Extract and Load Architecture
The extract and load data pipeline pattern focuses on the tools and options to bring data into BigQuery by eliminating the need for upfront transformation. Extract and load greatly simplifies data ingestion into BigQuery. Extract and load leverages tools like 'bq load' and Data Transfer Service to directly load data from various sources or uses external tables and BigLake tables to make data accessible via BigQuery. This pattern also offers scheduling capabilities and eliminates the need for data copying, promoting efficiency in data pipelines. BigQuery provides extensive flexibility in data handling. It supports loading data from various formats like Avro, Parquet, ORC, CSV, JSON, as well as Firestore exports. Similarly, you can export BigQuery artifacts, including query results and table data, into formats like CSV, JSON, Avro, and Parquet, facilitating easy integration with other tools and systems. BigQuery offers two ways to load data: through its friendly user interface for file uploads, or via the LOAD DATA SQL statement. The UI simplifies the process, allowing you to select files, specify formats, and even auto-detect schema. LOAD DATA provides more control, ideal for automation and appending or overriding existing tables.2. Let's practice!
