Databricks Assistant: AI Copilot for SQL & ETL

Data engineers and analysts spend a significant portion of their time writing SQL queries, transforming data, and debugging pipelines. Even experienced professionals often struggle with complex joins, aggregations, or transformations.

Databricks Assistant acts as an AI Copilot, helping teams write SQL, automate ETL tasks, and gain insights faster. It integrates seamlessly into the Databricks environment, making AI assistance accessible directly within SQL notebooks and pipelines.


Why Databricks Assistant Matters

Imagine a scenario where you need to generate a complex revenue report across multiple regions and product categories:

  • Writing the SQL query manually could take hours.
  • Testing and debugging joins across multiple tables is error-prone.
  • ETL tasks for cleaning or aggregating data add more complexity.

Databricks Assistant addresses these challenges by offering:

  • AI-generated SQL queries based on natural language
  • Automated ETL recommendations for data transformations
  • Instant suggestions for joins, filters, and aggregations
  • Context-aware insights using your data schema

How Databricks Assistant Works

  1. Understand Context: Assistant reads your schema, table metadata, and current notebook context.
  2. Natural Language Queries: You describe your task in plain English.
  3. Generate SQL or ETL Code: Assistant provides executable code, ready for testing.
  4. Iterate & Refine: You can tweak suggestions or let Assistant optimize queries further.

Example 1: Generate SQL Query from Natural Language

Instruction:


"Get total revenue per product category for Q4 2025 and order by descending revenue"

Databricks Assistant Output:

SELECT product_category, SUM(revenue) AS total_revenue
FROM sales_data
WHERE sale_date BETWEEN '2025-10-01' AND '2025-12-31'
GROUP BY product_category
ORDER BY total_revenue DESC;

Example Output Table:

product_categorytotal_revenue
Electronics1,500,000
Apparel1,200,000
Home Goods950,000

Example 2: ETL Task Recommendation

Suppose you have messy customer_feedback data. Assistant can suggest a cleaning and aggregation pipeline:

# Databricks Assistant suggested ETL
cleaned_feedback = (
spark.read.table("customer_feedback")
.withColumn("feedback_clean", F.regexp_replace("feedback", "[^a-zA-Z0-9 ]", ""))
.groupBy("customer_id")
.agg(F.collect_list("feedback_clean").alias("all_feedback"))
)

Example Input/Output:

Input Table:

customer_idfeedback
1"Great service!!!"
1"Fast delivery, thanks"
2"Product broke :("

Output Table:

customer_idall_feedback
1["Great service", "Fast delivery thanks"]
2["Product broke"]
