CData Connect Server


Use CData Connect Server to create a virtual MySQL Database for Parquet data to build custom dashboards in Bold BI.

Bold BI allows you to create, share, and collaborate on interactive BI dashboards. When paired with CData Connect Server, you get instant access to Parquet data for visualizations, dashboards, and more. This article shows how to create a virtual database for Parquet and build reports from Parquet data in Bold BI.

CData Connect Server provides a pure MySQL interface for Parquet, allowing you to easily build reports from live Parquet data in Bold BI — without replicating the data to a natively supported database. As you build visualizations, Bold BI generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to Parquet, leveraging server-side processing to quickly return the requested Parquet data.

Create a Virtual MySQL Database for Parquet Data

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

  1. Login to Connect Server and click Databases.
  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 Test Database.
  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 data from Bold BI.
