Kunal Mittal updated SLING-9174:
--------------------------------
Description:
The SDI module currently includes the path of the component in the SSI
directive which creates the cache under the page where the component is added.
There are number of cases where we create content which gets reused across the
website. In order to achieve reusability, we create proxy components which in
turn makes a call to the reusable content pages.
*EXAMPLE*
Proxy component: banner-proxy
Reusable content page: /content/sdi/us/en/content/banner
Pages: /content/sdi/us/en/test-sdi1, /content/sdi/us/en/test-sdi2
The banner-proxy component exists on both pages: test-sdi1 and test-sdi2 page
to render /content/sdi/us/en/content/banner.
If we enable SDI and enable caching for banner-proxy component then 2 cache
entries get created:
/content/sdi/us/en/test-sdi1/_jcr_content/root/banner-proxy and
/content/sdi/us/en/test-sdi2/_jcr_content/root/banner-proxy
When any change is made to /content/sdi/us/en/content/banner page, it should
reflect the changes on test-sdi1 and test-sdi2 page for which we need to write
extra code to find the occurrences of where the proxy banner component is used
to evict the cache.
With the enhancement as the SSI directive includes the path of the content:
/content/sdi/us/en/content/banner, the system creates a single cache entry for
the pages where it is referenced in. When the page is updated, the cache will
be evicted which will be reflected on all the pages.
*Benefits*:
# Performance
** Considerably reduces the number of calls to Publisher
# Cache Optimisation
** No custom code to invalidate cache entries created under every page
*Current implementation*:
{code:java}
## Directive added in the page after processing of SDI
<!--#include
virtual="/content/sdi/us/en/test-sdi1/_jcr_content/root/banner-proxy.nocache.html"
-->
{code}
*Enhancement*:
{code:java}
## Directive added in the page after processing of SDI
<!--#include virtual="/content/sdi/us/en/content/banner.content.nocache.html"
-->
{code}
