Chapter 1: Introduction to the Integration

For many, the long-awaited integration of Google BigQuery with Apache Spark has finally arrived. This new feature allows users to execute stored procedures in Google BigQuery SQL that utilize Apache Spark.

Spark is designed to execute data queries on extensive datasets from various sources, offering high-speed performance through its distributed architecture and cluster computing capabilities. Google has now announced that users can create and execute Apache Spark stored procedures written in Python within BigQuery. This process is as straightforward as running SQL stored procedures, allowing for a seamless experience. A stored procedure in BigQuery is essentially a series of statements callable from other queries or stored procedures, capable of accepting input parameters and returning output values.

Before diving into coding, it is essential to establish a connection to Apache Spark. Fortunately, this setup is quite simple:

Once the connections are set up, users can begin coding and create stored procedures utilizing Apache Spark. Here’s a sample blueprint:

CREATE PROCEDURE YOUR_PROJECT_ID.YOUR_DATASET.PROCEDURE_NAME(PROCEDURE_ARGUMENT)

WITH CONNECTION CONNECTION_NAME

OPTIONS (

engine="SPARK",

main_file_uri=["URI"]);

LANGUAGE PYTHON [AS PYSPARK_CODE]

Apache Spark is well-suited for a multitude of applications within the Big Data landscape due to its speed and versatility in handling large datasets from various origins. This initiative by Google is indeed a logical step forward. As a well-established Big Data framework, Apache Spark is widely adopted by numerous users and organizations. Consequently, customers leveraging Apache Spark can now also benefit from the capabilities of BigQuery, allowing for a more integrated experience.

Key application areas for Apache Spark include:

• Data Integration
• Ad Hoc Analysis of Big Data
• Machine Learning

These areas align perfectly with the strengths of BigQuery, making this development exciting news for users.

Additionally, Google has introduced several other significant updates in recent weeks:

• Now Available: Multi Statement Transactions in BigQuery
• BigQuery SQL now supports Multi Statement Transactions
• Is Google BigLake the New Challenger to Snowflake, Redshift, and Others?
• How the New Service Facilitates Platform-Independent Data Analysis
• Enhanced Integration of BigQuery and Colab
• Discover how you can now effortlessly use Python within Google BigQuery.
