Processing Components

20. Talend for Data Integration and Big Data www.edureka.co/talend-for-big-data
tMap
It is used for simple reorganization of fields to the most complex data transformational Jobs
It helps in transforming and routing data from single or multiple sources to single or multiple destinations
This is an advanced component which is integrated to the Talend Studio as a plugin

21. Talend for Data Integration and Big Data www.edureka.co/talend-for-big-data
tJoin
It ensures that the data quality of data from any source against a reference data source
It compares columns from the main flow with reference columns from the lookup flow & outputs the main flow or rejected data
This component helps in joining two tables by doing an exact match on several columns

22. Talend for Data Integration and Big Data www.edureka.co/talend-for-big-data
tFilterRow
The schema of this component is read-only
It helps in parametrizing filters on the source data/ incoming data
This component helps in filtering input rows by setting one or more conditions on the selected columns

23. Talend for Data Integration and Big Data www.edureka.co/talend-for-big-data
tSortRow
This component is defined as an intermediary step as it requires input and output to handle the flow of data
