Select Local. Your annotation group will only be saved into your transformation. Any user running this transformation can see and use the annotations group.
Click Select Fields to begin creating annotations to populate the group. See steps 6-8 in Use the Annotate Stream step for more information on selecting and annotating fields.
When you are done, click Apply to save your annotation group locally.
If you later decide that you want to share the annotation group, you can reopen it and select the Shared radio button, then click Apply. The group will then be shared to the metastore and be available to other users.
