Integrate Elasticsearch Data in Your Informatica Cloud Instance

Informatica Cloud allows you to perform extract, transform, and load (ETL) tasks in the cloud. With the Cloud Secure Agent and the CData JDBC Driver for Elasticsearch, you get live access to Elasticsearch data, directly within Informatica Cloud. In this article, we will walk through downloading and registering the Cloud Secure Agent, connecting to Elasticsearch through the JDBC Driver and generating a mapping that can be used in any Informatica Cloud process.

Informatica Cloud Secure Agent

To work with the Elasticsearch data through the JDBC Driver, install the Cloud Secure Agent.

1. Navigate to the Administrator page in Informatica Cloud
2. Select the Runtime Environments tab
3. Click "Download Secure Agent"
4. Make note of the Install Token
5. Run the installer on the client machine and register the Cloud Secure Agent with your username and install token

NOTE: It may take some time for all of the Cloud Secure Agent services to get up and running.

Connecting to the Elasticsearch JDBC Driver

With the Cloud Secure Agent installed and running, you are ready to connect to Elasticsearch through the JDBC Driver.

Adding the JDBC Driver to the Secure Agent Machine

1. Navigate to the following directory on the Secure Agent machine:
   %Secure Agent installation directory%/ext/connectors/thirdparty/
2. Create a folder and add the driver JAR file (cdata.jdbc.elasticsearch.jar) based on the type of mapping that you want to configure.

   For mappings, create the following folder and add the driver JAR file:

   informatica.jdbc_v2/common

   For mappings in advanced mode, also create the following folder and add the driver JAR file:

   informatica.jdbc_v2/spark
3. Restart the Secure Agent.

Connecting to Elasticsearch in Informatica Cloud

• Connection Name: Name your connection (i.e.: CData Elasticsearch Connection)
• Type: Select "JDBC_V2"
• Runtime Environment: Select the runtime environment where you installed the Secure Agent
• JDBC Driver Class Name: The name of the JDBC driver class: cdata.jdbc.elasticsearch.ElasticsearchDriver
• JDBC Connection URL: Set this to the JDBC URL for Elasticsearch. Your URL will look similar to the following:
  
  jdbc:elasticsearch:Server=127.0.0.1;Port=9200;User=admin;Password=123456;

  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.

  Built-In Connection String Designer

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

  java -jar cdata.jdbc.elasticsearch.jar

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

• Username: Set this to the username for Elasticsearch
• Password: Set this to the password for Elasticsearch

Create a Mapping for Elasticsearch Data

With the connection to Elasticsearch configured, we can now access Elasticsearch data in any Informatica process. The steps below walk through creating a mapping for Elasticsearch to another data target.

1. Navigate to the Data Integration page
2. Click New.. and select Mapping from the Mappings tab
3. Click the Source Object and in the Source tab, select the Connection and set the Source Type
4. Click "Select" to choose the table to map
5. In the Fields tab, select the fields from the Elasticsearch table to map
6. Click the Target object and configure the Target source, table and fields. In the Field Mapping tab, map the source fields to the target fields.

With the mapping configured, you are ready to start integrating live Elasticsearch data with any of the supported connections in Informatica Cloud. Download a free, 30-day trial of the CData JDBC Driver for Elasticsearch and start working with your live Elasticsearch data in Informatica Cloud today.
