詳細はこちら →Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Spark, you gain access to live Spark データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Spark データ. This article will walk through connecting to Spark using the Data Explorer.
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Databricks クラスターに接続するには、以下の説明に従ってプロパティを設定します。Note:必要な値は、「クラスター」に移動して目的のクラスターを選択し、 「Advanced Options」の下にある「JDBC/ODBC」タブを選択することで、Databricks インスタンスで見つけることができます。
You can create a simple application for displaying Spark データ by utilizing the CData FireDAC Components for Spark and a new VCL Forms Application:
Create a new VCL Forms application and drag a table (for example: Customers) onto the form.
Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).
Arrange the TStringGrid on the form and run the application to see the Customers data.
