Process & Analyze SpaceX Data 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 SpaceX data. This article explains how to host the CData JDBC Driver in AWS, as well as connect to and process live SpaceX data in Databricks.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SpaceX data. When you issue complex SQL queries to SpaceX, the driver pushes supported SQL operations, like filters and aggregations, directly to SpaceX 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 SpaceX data using native data types.
Install the CData JDBC Driver in Databricks
To work with live SpaceX data in Databricks, install the driver on your Databricks cluster.
- Navigate to your Databricks administration screen and select the target cluster.
- On the Libraries tab, click "Install New."
- Select "Upload" as the Library Source and "Jar" as the Library Type.
- Upload the JDBC JAR file (cdata.jdbc.api.jar) from the installation location (typically C:\Program Files\CData[product_name]\lib).
Access SpaceX Data in your Notebook: Python
With the JAR file installed, we are ready to work with live SpaceX data 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 SpaceX, and create a basic report.
Configure the Connection to SpaceX
Connect to SpaceX by referencing the JDBC Driver class and constructing a connection string to use in the JDBC URL. Additionally, you will need to set the RTK 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.api.APIDriver" url = "jdbc:api:RTK=5246...;Profile=C:\profiles\SpaceX.apip;"
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the SpaceX JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.api.jar
Fill in the connection properties and copy the connection string to the clipboard.
Start by setting the Profile connection property to the location of the SpaceX Profile on disk (e.g. C:\profiles\SpaceX.apip). Next, set the ProfileSettings connection property to the connection string for SpaceX (see below).
SpaceX API Profile Settings
No authentication is required to access SpaceX data — the SpaceX API is publicly available. Simply set the Profile connection property to the path of the SpaceX profile file.
Load SpaceX Data
Once you configure the connection, you can load SpaceX data 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" , "Capsules") \ .load ()
Display SpaceX Data
Check the loaded SpaceX data by calling the display function.
Step 3: Checking the result
display (remote_table.select ("CapsuleSerial"))
Analyze SpaceX Data 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 SpaceX data for reporting, visualization, and analysis.
% sql SELECT CapsuleSerial, CapsuleId FROM SAMPLE_VIEW ORDER BY CapsuleId DESC LIMIT 5
The data from SpaceX 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" )
