Filter Processor
Data filtering is required to refine the datasets so that you simply get what you need excluding other data that can be repetitive, irrelevant or sensitive. Different type of filters can be used to query results or other kind of information.
The Filter processor is used to display specific records by using filter criteria. For example, you can define the Filter rule: grade contains “software” and name contains “Mike”. The system will fetch all the records which meet this criteria.
