Build Pipelines with Live Elasticsearch Data in Google Cloud Data Fusion (via CData Connect Cloud)


Use CData Connect Cloud to connect to Elasticsearch from Google Cloud Data Fusion, enabling the integration of live Elasticsearch data into the building and management of effective data pipelines.

Google Cloud Data Fusion simplifies building and managing data pipelines by offering a visual interface to connect, transform, and move data across various sources and destinations, streamlining data integration processes. When combined with CData Connect Cloud, it provides access to Elasticsearch data for building and managing ELT/ETL data pipelines. This article explains how to use CData Connect Cloud to create a live connection to Elasticsearch and how to connect and access live Elasticsearch data from the Cloud Data Fusion platform.

About Elasticsearch Data Integration

Accessing and integrating live data from Elasticsearch has never been easier with CData. Customers rely on CData connectivity to:

  • Access both the SQL endpoints and REST endpoints, optimizing connectivity and offering more options when it comes to reading and writing Elasticsearch data.
  • Connect to virtually every Elasticsearch instance starting with v2.2 and Open Source Elasticsearch subscriptions.
  • Always receive a relevance score for the query results without explicitly requiring the SCORE() function, simplifying access from 3rd party tools and easily seeing how the query results rank in text relevance.
  • Search through multiple indices, relying on Elasticsearch to manage and process the query and results instead of the client machine.

Users frequently integrate Elasticsearch data with analytics tools such as Crystal Reports, Power BI, and Excel, and leverage our tools to enable a single, federated access layer to all of their data sources, including Elasticsearch.

Getting Started


Configure Elasticsearch Connectivity for Cloud Data Fusion

Connectivity to Elasticsearch from Cloud Data Fusion is made possible through CData Connect Cloud. To work with Elasticsearch data from Cloud Data Fusion, we start by creating and configuring a Elasticsearch connection.

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "Elasticsearch" from the Add Connection panel
  3. Enter the necessary authentication properties to connect to Elasticsearch.

    Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.

    The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.

    Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.

  4. Click Create & Test
  5. Navigate to the Permissions tab in the Add Elasticsearch Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Elasticsearch data from Cloud Data Fusion.

Connecting to Elasticsearch from Cloud Data Fusion

Follow these steps to establish a connection from Cloud Data Fusion to Elasticsearch through the CData Connect Cloud JDBC driver:

  1. Download and install the CData Connect Cloud JDBC driver:
    1. Open the Client Tools page of CData Connect Cloud.
    2. Search for JDBC or Cloud Data Fusion.
    3. Click on Download and select your operating system (Mac/Windows/Linux).
    4. Once the download is complete, run the setup file.
    5. When the installation is complete, the JAR file can be found in the installation directory (inside the lib folder).
  2. Log into Cloud Data Fusion.
  3. Click the green "+" button at the top right to add an entity.
  4. Under Driver, click Upload.
  5. Now, upload the CData Connect Cloud JDBC driver (JAR file).
  6. Enter the driver settings:
    • Name: Enter the name of the driver
    • Class name: Enter "cdata.jdbc.connect.ConnectDriver"
    • Version: Enter the driver version
    • Description (optional): Enter a description for the driver
  7. Click on Finish.
  8. Enter source configuration settings:
    • Label: Helps to identify the connection
    • JDBC driver name: Enter the JDBC driver name to identify the driver configured in Step 6.
    • Connection string: Enter the JDBC connection string and include the following parameters in it: jdbc:connect:AuthScheme=Basic;User=[User];Password=[Password];
    • User: Enter your CData Connect Cloud username, displayed in the top-right corner of the CData Connect Cloud interface. For example, "test@cdata.com"
    • Password: Enter the PAT you generated on the Settings page.
  9. Click Validate in the top right corner.
  10. If the connection is successful, you can manage the pipeline by editing it through the UI.
  11. Run the pipepline created.

Troubleshooting

Please be aware that there is a known issue in Cloud Data Fusion where "int" types from source data are automatically cast as "long".

Live Access to Elasticsearch Data from Cloud Applications

Now you have a direct connection to live Elasticsearch data from from Google Cloud Data Fusion. You can create more connections to ensure a smooth movement of data across various sources and destinations, thereby streamlining data integration processes - all without replicating Elasticsearch data.

To get real-time data access to 100+ SaaS, Big Data, and NoSQL sources (including Elasticsearch) directly from your cloud applications, explore the CData Connect Cloud.
