Query Parquet 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 Parquet data as if it were a MySQL database. This article shows how to create a virtual database for Parquet in Connect and work with live Parquet data in MySQL Workbench.

Create a Virtual MySQL Database for Parquet 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 "Parquet" from Available Data Sources.
3. Enter the necessary authentication properties to connect to Parquet.

   Connect to your local Parquet file(s) by setting the URI connection property to the location of the Parquet file.

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 Parquet from MySQL Workbench.
