Summary

The Link Collector stage is an active stage which takes up to 64 inputs and allows you to collect data from these links and route it along a single output link. The stage expects the output link to use the same metadata as the input links.

Parallel Stages: The Link Collectors is implemented as a combination of the following stages:

• Local Container - Local containers - IBM Documentation

• Copy Stage - Copy stage - IBM Documentation

• Funnel Stage - Funnel Stage - IBM Documentation

Conversion Notes

Structural changes

The output of the Server Link Collector translation process follows the same structure as the Server Link Collector stage itself: multiple inputs with a single output. The Server Link Collector stage is replaced with an identically-named Parallel Local Container within which is the following implementation:

• Each Server Link Collector input link is translated into a Container input link.

• The Server Link Collector output link is translated into a Container output link.

• Each container input link has a Parallel Copy Stage which acts to rename columns to align with expected output metadata definitions.

• Each Parallel Copy Stage is connected to a Parallel Funnel which combines results into a single Container output link based on the Collection Algorithm and (for the Sort/Merge option) Sort Key properties derived from those of the original Server Link Collector.
