To merge segments, create a segment set and then run the merge partitions into single partition standalone job. When you finish merging the partitions, run the clean up after merge partitions standalone job to make the changes final.
Create a segment set that contains the segments that you want to merge together. For more information, see the topic "Segment Sets" in this chapter.
Schedule the merge partitions to single partition standalone job. For more information about the standalone job, see the
Scheduling Jobs
chapter.
The merge partitions into single partition job merges the data from the older partitions into the most recent partition.
When the standalone job completes successfully, click
Workbench
Manage Segmentation
.
In the lower pane of the
Manage Segmentation
window, verify that the segment set has merged correctly. The older segments in the set will have the status "Merged." The job renames the most recent segment to a combination of the merged segment names. This segment has the status "Implemented."
If for any reason you need to reverse the merge, run the replace merged partitions with original partitions standalone job before you continue.
Repeat steps 1-4 for each segment set that you want to merge.
When you finish merging segments, run the clean up after merge partitions standalone job. For more information, see the
Scheduling Jobs
chapter.
The run clean up after merge partitions job drops the empty partitions and merges the partition metadata. After you run the job, only the merged partition appears in the
