Can a block be cached for period of time?

[Pakkapao]

Hi,

Is it possible to cache a block for period of time, for example, it expires every 15 minutes? I would like to display a block on sidebar for all pages and to avoid performance issue as the information inside the block doesn't change frequently.

Is there an xml parameter available to do that?

<referenceContainer name="sidebar.additional">
    <block class="xxx" before="-" name="xxx" template="xxx.phtml" cacheable="true"/>
</referenceContainer>

Thanks,

Yes. A "ttl" attribute designed for setting cache lifetime for a block in seconds.

<referenceContainer name="sidebar.additional">
    <block class="xxx" before="-" name="xxx" template="xxx.phtml" cacheable="true" ttl="900"/>
</referenceContainer>

See sample in app/code/Magento/Doc/view/doc/layout/default.xml

Thank you for your help, rganin. 👍
I tried searching an example from code base before but didn't found any of them. I must have looked over them.

You can find an example in file vendor/magento/module-theme/view/frontend/layout/default.xml

 <block class="Magento\Framework\View\Element\Template" name="store.menu" group="navigation-sections" template="Magento_Theme::html/container.phtml">
                    <arguments>
                        <argument name="title" translate="true" xsi:type="string">Menu</argument>
                    </arguments>
                    <block class="Magento\Theme\Block\Html\Topmenu" name="catalog.topnav" template="html/topmenu.phtml" ttl="3600" before="-"/>
                </block>

hi @jarnail1004 , I try this "ttl" attribute with a "60" value to have 1 minute for the cache lifetime, but it didn't work, like you. Do you have some information about it ?

[jarnail1004]

@agoeurysky , this works only if you are using Varnish cache.
