Select the desired database type from the list and click Apply.

Schema and Edit schema

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 line when naming the fields.

• Built-In: You create and store the schema locally for this component only.

• Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

Click Edit schema to make changes to the schema. If you make changes, the schema automatically becomes built-in.

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion.

  If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

This component offers the advantage of the dynamic schema feature. This allows you to retrieve unknown columns from source files or to copy batches of columns from a source without mapping each column individually. For further information about dynamic schemas, see Dynamic schema.

This dynamic schema feature is designed for the purpose of retrieving unknown columns of a table and is recommended to be used for this purpose only; it is not recommended for the use of creating tables.

Table Name

The name of the table into which data will be written.

Bulk file

Name of the bulk file to write data into.

Append

Select this option if you want to append the incoming data to an existing bulk file.

This option prevents the data in an exisitng file from being overwritten.

Row Separator

The separator used to identify the end of a row.

Field separator

Enter a character, a string, or a regular expression to separate fields for the transferred data.

Set text enclosure

Select this option to set the text enclosure. You can enter the enclosure character (only one character) between double quotation marks in the text field to the right. For example, to use double quotation mark (") as the enclosure character, enter """ in this field.

It is recommended to use standard escape character, that is "\". Otherwise, you should set the same character for Escape char and Text enclosure. If the escape character is set to "\", the text enclosure can be set to any other character; if the escape character is set to a character other rather than "\", it will be changed to the same character as the text enclosure. For example, with the escape character set to "#" and the text enclosure set to "@", the escape character will be changed to "@".

Set null value

Select this option to set the null value. You can set the null value in the field to the right.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level as well as at each component level.

ERROR_MESSAGE

The error message generated by the component when an error occurs. This is an After variable and it returns a string.

Usage rule

This component is used along with the tSingleStoreBulkExec. They provide performance gains when feeding a database.
