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.

Click Sync
columns to retrieve the schema from the previous component connected in the
Job.

Click Edit
schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• 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.

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.

Password

Enter the password used to encrypt the
cryptographic file generated by the tDataEncrypt
component.

This value must be enclosed in double
quotes.

Cryptographic file
path

Enter the path to the cryptographic file used
to encrypt the input data with the tDataEncrypt component.

This value must be enclosed in double
quotes.

Decryption

Select the corresponding Decrypt check boxes to decrypt input columns.

The columns that are not selected will not be
decrypted. Properly configure the output schema of the component to set the type of the
columns to be decrypted to String.

If you try to decrypt unencrypted columns,
the component outputs null values in those columns.

tStat Catcher Statistics

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

Usage rule

This component is usually used as an intermediate component, and it requires an
input component and an output component.
