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

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.

What are the different types of transformations in Informatica?

There are 3 Informatica transformations viz. External Procedure, Lookup, and Stored Procedure which can be unconnected in a valid mapping (A mapping which the Integration Service can execute).

What is update strategy transformation active or passive?

Update strategy transformation is an active and connected transformation. Update strategy transformation is used to insert, update, and delete records in the target table. It can also reject the records without reaching the target table.

Why Union is active transformation in Informatica?

The Union transformation is an active transformation that you use to merge data from multiple pipelines into a single pipeline. For data integration patterns, it is common to combine two or more data sources into a single stream that includes the union of all rows.

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.

Is unconnected lookup active or passive?

When you configure the Lookup transformation to return a single row, the Lookup transformation is a passive transformation. When you configure the Lookup transformation to return multiple rows, the Lookup transformation is an active transformation. You can use multiple Lookup transformations in a mapping.

Why we use pushdown optimization in Informatica?

Pushdown Optimization is use to increase data processing performance extremely. Always processing data on database level is faster than processing data in Informatica level. Pushdown Optimization is a concept of push Informatica transformation logic on source or target when they are database table.

Is Lookup transformation active or passive?

Is router active or passive transformation?

The Router transformation is an active transformation that you can use to apply a condition to incoming data.

Is Union active or passive transformation?

Is rank transformation active or passive?

Rank is an active and connected transformation that performs the filtering of data based on the group and ranks.

What is the difference between active and passive transformations?

Active and passive transformations 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.

What is a passive transformation in Informatica?

A passive transformation does not change the number of rows that pass through the transformation. You can connect multiple branches to a downstream passive transformation when all transformations in the branches are passive. Which of the following is passive transformation in Informatica?

What is transformation in Informatica powercenter?

In this article, i tell something about acitve and passive transformation of informatica powercenter. Reading, manupulating and loading data is called transformation in informatica. Each transformations perform specific functions. There are two type of transformations, passive and active transformations.

What is connected and unconnected transformation in Informatica?

All the active and passive transformation can call as connected transformations in Informatica. A connected transformation can receive / or provide multiple input ports Within the Mappings, if a transformation not connected to other transformations, then we can call it as Unconnected Transformation in Informatica.
