Elasticsearch Icon Elasticsearch ODBC Driver

The Elasticsearch ODBC Driver is a powerful tool that allows you to connect with live Elasticsearch document databases, directly from any applications that support ODBC connectivity.

Access Elasticsearch like you would a database - read, write, and update through a standard ODBC Driver interface.

Create Informatica Mappings From/To an ODBC Data Source for Elasticsearch


Create an ODBC connection to Elasticsearch in Informatica and browse and transfer Elasticsearch data.

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData ODBC Driver for Elasticsearch, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to transfer and browse Elasticsearch data in Informatica PowerCenter.

Connect to Elasticsearch as an ODBC Data Source

Information for connecting to Elasticsearch follows, along with different instructions for configuring a DSN in Windows and Linux environments.

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.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for Elasticsearch in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData Elasticsearch Source] Driver = CData ODBC Driver for Elasticsearch Description = My Description Server = 127.0.0.1 Port = 9200 User = admin Password = 123456

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a Linked Table to Orders Data

Follow the steps below to create a linked table, which enables you to access live Orders data.

Create the ODBC Connection

Follow the steps below to connect to Elasticsearch in Informatica PowerCenter:

  1. In the Informatica Developer tool connect to your repository and create a project.
  2. In the Connection Explorer pane, right-click and click Create a Connection.
  3. In the New Database Connection wizard that is displayed, enter a name and Id for the connection and in the Type menu select ODBC.
  4. In the Connection String property, enter the DSN.

NOTE: If you are working in a Linux operating system, set the Driver Manager for Linux property to unixODBC 2.3.x.

Create the Elasticsearch Data Object

After you have created an ODBC connection to Elasticsearch, you can now access Elasticsearch entities in Informatica. Follow the steps below to add Orders entities to your project.

  1. In the Object Explorer, right-click your project and then click New -> Data Object.
  2. In the wizard that is displayed, select the Relational Data Object option.
  3. Click the Browse button next to the Connection box and select the ODBC connection you created in the previous step.
  4. Select the option to create a data object from an existing resource and click the Browse button next to the Resource box.
  5. In the dialog that is displayed, clear the Show Default Schema Only option and expand the node for the ODBC connection. Select the entity that you want.

You can now browse the table in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.

Create the Mapping

Follow the steps below to add the Elasticsearch source to a mapping:

  1. In the Object Explorer, right-click your project and then click New -> Mapping.
  2. Expand the node for the Elasticsearch connection and then drag the data object for the table onto the editor.
  3. In the dialog that appears, select the Read option.

Follow the steps below to map Elasticsearch columns to a flat file:

  1. In the Object Explorer, right-click your project and then click New -> Data Object.
  2. Select Flat File Data Object -> Create as Empty -> Fixed Width.
  3. In the properties for the Elasticsearch object, select the rows you want, right-click, and then click copy. Paste the rows into the flat file properties.
  4. Drag the flat file data object onto the mapping. In the dialog that appears, select the Write option.
  5. Click and drag to connect columns.

To transfer Elasticsearch data, right-click in the workspace and then click Run Mapping.
