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. A partition can get replication tasks assigned, that
if chosen for a replication process that has page cache invalidation strategy 'Invalidate
Impacted Cache Partitions' selected, causes the partition to be invalidated at the end of the
replication process.
Before creating page cache partitions, understand the relative execution time of each
pipeline, so that you can avoid putting too many pipelines in the same partition. Also, be
aware of what pieces of the storefront are cached.
The page cache for remote includes and
iscomponent elements aren’t 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.
-
Select .
-
From the Cache tab, under Page Partitions, click Add
Partition.
-
Enter the following:
| Option |
Description |
| ID |
Enter a unique, meaningful ID for the partition. It can only contain
characters allowed in URLs. |
| Name |
Enter a name that describes the type of pipelines you’re including in your
partition. For example: slot configurations and slot content. |
-
From the Pipelines tab, add pipeline names or remove existing ones.
Use the Pipeline-StartNode name, for example: Home-Show.
Pipeline names can be for the current site or for remote includes. A pipeline can
only appear in one partition. Modifying an existing partition by removing a
pipeline sets the page cache clear time to the partition clear time, which can
invalidate cached content.
If your storefront is based on SiteGenesis, you should import the partition
definitions included with SiteGenesis.
If your storefront is based on SFRA or SiteGenesis, import the partition
definitions included with SFRA or SiteGenesis.
-
From the Tab Replication Tasks tab, choose any Global or Site-specific replication
tasks.
If a replication process that has a page cache invalidation strategy of
'Invalidate Impacted Cache Partitions' is selected, the partition is invalidated at
the end of the replication process.
