Query Impala Data in MySQL Workbench

MySQL Workbench allows users to administer MySQL environments and gain better visibility into databases. When paired with CData Connect (on-premise or Connect Server), you get live access to Impala data as if it were a MySQL database. This article shows how to create a virtual database for Impala in Connect and work with live Impala data in MySQL Workbench.

Create a Virtual MySQL Database for Impala Data

CData Connect uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect and click Connections.
2. Select "Impala" from Available Data Sources.
3. Enter the necessary authentication properties to connect to Impala.

   In order to connect to Apache Impala, set the Server, Port, and ProtocolVersion. You may optionally specify a default Database. To connect using alternative methods, such as NOSASL, LDAP, or Kerberos, refer to the online Help documentation.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Impala from MySQL Workbench.

Query Impala from MySQL Workbench

The steps below outline connecting to the virtual Impala database in Connect from MySQL Workbench and issuing basic queries to work with live Impala data.

Connect to Impala through Connect

1. In MySQL Workbench, click to add a new MySQL connection.
2. Name the connection (CData Connect).
3. Set the Hostname, Port, and Username parameters to connect to the SQL Gateway.
4. Click Store in Vault to set and store the password.
5. Click Test Connection to ensure the connection is configured properly and click OK.

Query Impala Data

1. Open the connection you just created (CData Connect).
2. Click File -> New Query Tab.
3. Write a SQL query to retrieve Impala data, like SELECT * FROM impaladb.Customers;

With access to live Impala data from MySQL Workbench, you can easily query and update Impala, just like you would a MySQL database. Request a demo of the CData Connect and start working with Impala just like a MySQL database today.
