All pipelines in a partition have their page caches invalidated together. As with a full page cache invalidation, the cache is gradually invalidated over 15 minutes. A pipeline can only be included in one partition. You can create a maximum of 10 partitions. Each partition can contain up to 10 pipelines.
The page cache for remote includes and
iscomponent
elements are not automatically invalidated when the page
cache for the pipeline that contains the rendering template is invalidated. Therefore, if
you want to refresh the content on the Home page by invalidating the Home-Show pipeline and
you have remote includes to Content-Show, then you must also explicitly invalidate the
Content-Show pipeline.
Pipelines are only allowed in one partition, but you might want to refresh different page types, such as the home page and product detail page. Therefore, Salesforce recommends that you place pipelines used in remote includes in a separate partition. Then, invalidate the main pipelines of the page in one partition and the content or other remote includes in the other.
