Information noteNote: This component does not support dynamic schema.

This component is available in Talend Real-Time Big Data Platform and Talend Data Fabric.

## Basic settings

| Properties | Description |
| --- | --- |
| Schema | <ul> <li> <p>A schema is a row description. It defines the number of fields            (columns) to be processed and passed on to the next component. When you create a Spark            Job, avoid the reserved word <kbd>line</kbd> when naming the            fields.</p> </li> <li> <p> <span>Built-In</span>: You create and store the schema locally for this component                only.</p> </li> <li> <p> <span>Repository</span>: You have already created the schema and stored it in the                Repository. You can reuse it in various projects and Job designs.</p> </li> </ul> |
| Edit Schema | Click Edit<br>schema to make changes to the schema. If the current schema is of the Repository type, three options are available:<br><br><ul> <li> <p> <span>View schema</span>: choose this                option to view the schema only.</p> </li> <li> <p> <span>Change to built-in property</span>:                choose this option to change the schema to <span>Built-in</span> for local changes.</p> </li> <li> <p> <span>Update repository connection</span>:                choose this option to change the schema stored in the repository and decide whether                to propagate the changes to all the Jobs upon completion.</p> <p>If you just want to                propagate the changes to the current Job, you can select <span>No</span> upon completion and choose this schema metadata                again in the <span>Repository Content</span>                window.</p> </li> </ul> |
| Transliteration | This table lists the columns defined in the schema of the tTransliterate component.<br><br>Select the Transliterate check box<br>next to the column(s) of which you want to convert the content to<br>readable standard set of characters. |

## Usage

| Usage guidance | Description |
| --- | --- |
| **Usage rule** | This component is used as an intermediate step.<br><br>This component, along with the Spark Structured Streaming component Palette it belongs to,<br>appears only when you are creating a Spark Structured Streaming Job. |
| Spark Connection | You need to use the Structured Streaming Configuration<br>tab in the Run view to define the connection to a Spark cluster for<br>the whole Job.<br><br>This connection is effective on a per-Job basis. |
