Developing a Custom Data Flow Component

  • Article

The data flow task consists of components that connect to a variety of data sources and then transform and route that data at high speed. Microsoft SQL Server Integration Services provides an extensible object model that lets developers create custom sources, transformations, and destinations that you can use in SQL Server Data Tools (SSDT) and in deployed packages. This section contains topics that will guide you in developing custom data flow components.

In This Section

Creating a Custom Data Flow Component Describes the initial steps in creating a custom data flow component.

Design-time Methods of a Data Flow Component Describes the design-time methods to implement in a custom data flow component.

Run-time Methods of a Data Flow Component Describes the run-time methods to implement in a custom data flow component.

Execution Plan and Buffer Allocation Describes the data flow execution plan and the allocation of data buffers.

Working with Data Types in the Data Flow Explains how the data flow maps Integration Services data types to .NET Framework managed data types.

Validating a Data Flow Component Explains the methods used to validate component configuration and to reconfigure component metadata.

Implementing External Metadata Explains how to use external metadata columns for data validation.

Raising and Defining Events in a Data Flow Component Explains how to raise predefined and custom events.

Logging and Defining Log Entries in a Data Flow Component Explains how to create and write to custom log entries.

Using Error Outputs in a Data Flow Component Explains how to redirect error rows to an alternative output.

Upgrading the Version of a Data Flow Component Explains how to update saved component metadata when a new version of your component is first used.

Developing a User Interface for a Data Flow Component Explains how to implement a custom editor for a component.

Developing Specific Types of Data Flow Components Contains information about developing the three types of data flow components: sources, transformations, and destinations.
