Access and process Zoom data in Apache Airflow using the CData JDBC Driver.
Apache Airflow supports the creation, scheduling, and monitoring of data engineering workflows. When paired with the CData API Driver for JDBC, Airflow can work with live Zoom data. This article describes how to connect to and query Zoom data from an Apache Airflow instance and store the results in a CSV file.
With built-in optimized data processing, the CData JDBC driver offers unmatched performance for interacting with live Zoom data. When you issue complex SQL queries to Zoom, the driver pushes supported SQL operations, like filters and aggregations, directly to Zoom 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 Zoom data using native data types.
Configuring the Connection to Zoom
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Zoom 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 Zoom Profile on disk (e.g. C:\profiles\Zoom.apip). Next, set the ProfileSettings connection property to the connection string for Zoom (see below).
Zoom API Profile Settings
To authenticate to Zoom, you can use the OAuth standard to connect to your own data or to allow other users to connect to their data.
First you will need to create an OAuth app. To do so, navigate to https://marketplace.zoom.us/develop/create and click Create under the OAuth section. Select whether or not the app will be for individual users or for the entire account, and uncheck the box to publish the app. Give the app a name and click Create. You will then be given your Client Secret and Client ID
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to OAuth.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
- OAuthClientID: Set this to the OAuth Client ID that is specified in your app settings.
- OAuthClientSecret: Set this to the OAuth Client Secret that is specified in your app settings.
- CallbackURL: Set this to the Redirect URI you specified in your app settings.
To host the JDBC driver in clustered environments or in the cloud, you will need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.
The following are essential properties needed for our JDBC connection.
Property | Value |
---|---|
Database Connection URL | jdbc:api:RTK=5246...;Profile=C:\profiles\Zoom.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;InitiateOAuth=GETANDREFRESH |
Database Driver Class Name | cdata.jdbc.api.APIDriver |
Establishing a JDBC Connection within Airflow
- Log into your Apache Airflow instance.
- On the navbar of your Airflow instance, hover over Admin and then click Connections.
- Next, click the + sign on the following screen to create a new connection.
- In the Add Connection form, fill out the required connection properties:
- Connection Id: Name the connection, i.e.: api_jdbc
- Connection Type: JDBC Connection
- Connection URL: The JDBC connection URL from above, i.e.: jdbc:api:RTK=5246...;Profile=C:\profiles\Zoom.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;InitiateOAuth=GETANDREFRESH)
- Driver Class: cdata.jdbc.api.APIDriver
- Driver Path: PATH/TO/cdata.jdbc.api.jar
- Test your new connection by clicking the Test button at the bottom of the form.
- After saving the new connection, on a new screen, you should see a green banner saying that a new row was added to the list of connections:
Creating a DAG
A DAG in Airflow is an entity that stores the processes for a workflow and can be triggered to run this workflow. Our workflow is to simply run a SQL query against Zoom data and store the results in a CSV file.
- To get started, in the Home directory, there should be an "airflow" folder. Within there, we can create a new directory and title it "dags". In here, we store Python files that convert into Airflow DAGs shown on the UI.
- Next, create a new Python file and title it zoom_hook.py. Insert the following code inside of this new file:
import time from datetime import datetime from airflow.decorators import dag, task from airflow.providers.jdbc.hooks.jdbc import JdbcHook import pandas as pd # Declare Dag @dag(dag_id="zoom_hook", schedule_interval="0 10 * * *", start_date=datetime(2022,2,15), catchup=False, tags=['load_csv']) # Define Dag Function def extract_and_load(): # Define tasks @task() def jdbc_extract(): try: hook = JdbcHook(jdbc_conn_id="jdbc") sql = """ select * from Account """ df = hook.get_pandas_df(sql) df.to_csv("/{some_file_path}/{name_of_csv}.csv",header=False, index=False, quoting=1) # print(df.head()) print(df) tbl_dict = df.to_dict('dict') return tbl_dict except Exception as e: print("Data extract error: " + str(e)) jdbc_extract() sf_extract_and_load = extract_and_load()
- Save this file and refresh your Airflow instance. Within the list of DAGs, you should see a new DAG titled "zoom_hook".
- Click on this DAG and, on the new screen, click on the unpause switch to make it turn blue, and then click the trigger (i.e. play) button to run the DAG. This executes the SQL query in our zoom_hook.py file and export the results as a CSV to whichever file path we designated in our code.
- After triggering our new DAG, we check the Downloads folder (or wherever you chose within your Python script), and see that the CSV file has been created - in this case, account.csv.
- Open the CSV file to see that your Zoom data is now available for use in CSV format thanks to Apache Airflow.
