Process & Analyze Google Search Results in Databricks (AWS)

Databricks is a cloud-based service that provides data processing capabilities through Apache Spark. When paired with the CData JDBC Driver, customers can use Databricks to perform data engineering and data science on live Google Search results. This article explains how to host the CData JDBC Driver in AWS, as well as connect to and process live Google Search results in Databricks.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Google Search results. When you issue complex SQL queries to Google Search, the driver pushes supported SQL operations, like filters and aggregations, directly to Google Search and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Google Search results using native data types.

Install the CData JDBC Driver in Databricks

To work with live Google Search results in Databricks, install the driver on your Databricks cluster.

1. Navigate to your Databricks administration screen and select the target cluster.
2. On the Libraries tab, click "Install New."
3. Select "Upload" as the Library Source and "Jar" as the Library Type.
4. Upload the JDBC JAR file (cdata.jdbc.googlesearch.jar) from the installation location (typically C:\Program Files\CData[product_name]\lib).

Access Google Search Results in your Notebook: Python

With the JAR file installed, we are ready to work with live Google Search results in Databricks. Start by creating a new notebook in your workspace. Name the notebook, select Python as the language (though Scala is available as well), and choose the cluster where you installed the JDBC driver. When the notebook launches, we can configure the connection, query Google Search, and create a basic report.

Configure the Connection to Google Search

Connect to Google Search by referencing the JDBC Driver class and constructing a connection string to use in the JDBC URL. Additionally, you will need to set the property in the JDBC URL (unless you are using a Beta driver). You can view the licensing file included in the installation for information on how to set this property.

Step 1: Connection Information

driver = "cdata.jdbc.googlesearch.GoogleSearchDriver"
url = "jdbc:googlesearch:RTK=5246...;CustomSearchId=def456;ApiKey=abc123;"

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Google Search JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.googlesearch.jar

Fill in the connection properties and copy the connection string to the clipboard.

To search with a Google custom search engine, you need to set the CustomSearchId and ApiKey connection properties.

To obtain the CustomSearchId property, sign into Google Custom Search Engine and create a new search engine.

To obtain the ApiKey property, you must enable the Custom Search API in the Google API Console.

Load Google Search Results

Once you configure the connection, you can load Google Search results as a dataframe using the CData JDBC Driver and the connection information.

Step 2: Reading the data

remote_table = spark.read.format ( "jdbc" ) \
	.option ( "driver" , driver) \
	.option ( "url" , url) \
	.option ( "dbtable" , "VideoSearch") \
	.load ()

Display Google Search Results

Check the loaded Google Search results by calling the display function.

Step 3: Checking the result

display (remote_table.select ("Title"))

Analyze Google Search Results in Databricks

If you want to process data with Databricks SparkSQL, register the loaded data as a Temp View.

Step 4: Create a view or table

remote_table.createOrReplaceTempView ( "SAMPLE_VIEW" )

With the Temp View created, you can use SparkSQL to retrieve the Google Search results for reporting, visualization, and analysis.

% sql

SELECT Title, ViewCount FROM SAMPLE_VIEW ORDER BY ViewCount DESC LIMIT 5

👁 Displaying Google Search Results

The data from Google Search is only available in the target notebook. If you want to use it with other users, save it as a table.

remote_table.write.format ( "parquet" ) .saveAsTable ( "SAMPLE_TABLE" )
