What is the default group in router transformation?

What groups are involved in Router transformation?

Output groups: Router transformation has two output groups. They are user-defined groups and default group. User-defined groups: Create a user-defined group to test a condition based on the incoming data. Each user-defined group consists of output ports and a group filter condition.

What is a Router transformation?

The Router transformation is an active transformation that you can use to apply a condition to incoming data. In a Router transformation, Data Integration. uses a filter condition to evaluate each row of incoming data. It tests the conditions of each user-defined group before processing the default group.

Why is Router active transformation?

Router transformation is an active and connected transformation which is similar to filter transformation, used to filter the source data. … In short the data which is rejected by the filter groups will be collected by this default group and sometimes there can be a requirement to store these rejected data.

What is a mapplet in Informatica?

A mapplet is a reusable object containing a set of transformations that you can use in multiple mappings. Use a mapplet in a mapping. Or, validate the mapplet as a rule. Transformations in a mapplet can be reusable or non-reusable. If you add a Sequence Generator transformation to a mapplet, it must be reusable.

What is the difference between reusable transformation and mapplet?

[vc_row][vc_column][vc_column_text]Mapplet consists of set of transformations which will contain a reusable business logic which can be reused across various mappings. A reusable transformation is a single transformation that can be reusable.

What is Joiner transformation?

Joiner transformation is an active and connected transformation. It provides the option of creating joins in the Informatica. By using the joiner transformation, the created joins are similar to the joins in databases. The joiner transformation is used to join two heterogeneous sources.

What is the difference between active and passive transformation in Informatica?

A transformation can be active or passive. An active transformation can change the number of rows that pass through the transformation. … A passive transformation does not change the number of rows that pass through the transformation.

Can we connect the same instance of target to multiple groups of router transformation?

You cannot connect more than one group to one target or a single input group transformation.

What is the difference between router and filter transformation?

Router transformation provides us the facility to capture the rows of data that do not meet any of the conditions to a default output group. A Filter transformation tests data for one condition and drops the rows of data that do not meet the condition. … Filter is single input and single output group transformation.

Is update strategy an active transformation?

The Update Strategy Transformation in Informatica is an Active and Connected transformation. It is useful to update, insert, or delete the records in a target based on source table data. And the beauty of this transformation is: you can restrict the records from not reaching into the target table.

Why rank is active transformation in Informatica?

Rank is an active and connected transformation that performs the filtering of data based on the group and ranks. … In Informatica, it is used to select a bottom or top range of data. While string value ports can be ranked, the Informatica Rank Transformation is used to rank numeric port values.

Why Union is an active transformation?

Union is an active transformation because it combines two or more data streams into one.
