Use CData drivers and the Birst Cloud Agent to build real-time visualizations of Elasticsearch data in Birst.
Birst is a cloud business intelligence (BI) tool and analytics platform that helps organizations quickly understand and optimize complex processes. When paired with the CData JDBC Driver for Elasticsearch, you can connect to live Elasticsearch data through the Birst Cloud Agent and build real-time visualizations. In this article, we walk you through, step-by-step, how to connect to Elasticsearch using the Cloud Agent and create dynamic reports in Birst.
With powerful data processing capabilities, the CData JDBC driver offers unmatched performance for live Elasticsearch data operations in Birst. When you issue complex SQL queries from Birst to Elasticsearch, the driver pushes supported SQL operations, like filters and aggregations, directly to Elasticsearch and utilizes the embedded SQL Engine to process unsupported operations client-side (often SQL functions and JOIN operations). With built-in dynamic metadata querying, the JDBC driver enables you to visualize and analyze Elasticsearch data using native Birst data types.
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 a JDBC Connection to Elasticsearch Data in Birst
Before creating the Birst project, you will need to install the Birst Cloud Agent (in order to work with the installed JDBC Driver). Also, copy the JAR file for the JDBC Driver (and the LIC file, if it exists) to the /drivers/ directory in the installation location for the Cloud Agent.
With the driver and Cloud Agent installed, you are ready to begin.
- Create a new project in Birst.
- Name the connection (e.g. CDataElasticsearch).
- Choose Live Access.
- Select an agent.
- Set Database Type to Other.
- Set SQL Type to MSSQL
- Set the Connection string.
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.
When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.
Below is a typical JDBC connection string for Elasticsearch:
jdbc:elasticsearch:Server=127.0.0.1;Port=9200;User=admin;Password=123456;
- Set the Driver Name: cdata.jdbc.elasticsearch.ElasticsearchDriver and click Save.
NOTE: Since authentication to Elasticsearch is managed from the connection string, you can leave Security Credentials blank.
Configure Elasticsearch Data Objects
Now that the connection is configured, we are ready to configure the schema for the dataset, choosing the tables, views, and columns we wish to visualize.
- Select the Schema (e.g. Elasticsearch).
- Click on Tables and/or Views to connect to those entities and click Apply.
- Select the Tables and Columns you want to access and click Done.
With the objects configured, you can perform any data preparation and discover any relationships in your data using the Pronto Prepare and Relate tools.
Build a Visualization
After you prepare your data and define relationships between the connected objects, you are ready to build your visualization.
- Select the Visualizer tool from the menu.
- Select Measures & Categories from your objects
- Select and configure the appropriate visualization for the Measure(s) you selected.
Using the CData JDBC Driver for Elasticsearch with the Cloud Agent and Birst, you can easily create robust visualizations and reports on Elasticsearch data. Download a free, 30-day trial and start building Birst visualizations today.
