Laravel Octane Cache Driver for faster statamic/ssg builds

[o1y]

I have had positive results using the Laravel Octane Cache Driver to generate our large Statamic project with statamic/ssg. Our project is generated about 80% faster with CACHE_DRIVER: octane.

I am aware that Swoole is not supported with Statamic (and possibly never will). However, it would be an interesting approach to at least speed up ssg with it. During my tests, it turned out that the build works in principle, but unfortunately, it leads to problems in some special cases with some Antlers Tag params.

In one scenario with enabled CACHE_DRIVER: octane when one of my templates uses collection Tag in combination with select parameter, during ssg this overrides the variable scope for some other entries being generated.

Perhaps @JohnathonKoster could take a look at this and see if this is really related to Antlers. If this issue is not related to Antlers and cannot be resolved without making bigger changes to Statamic Core, that would be unfortunate. However, I do not want to give up on this approach too fast, as it shows great potential to speed up things on larger projects. :)

This discussion is only about ssg, I'm not planning to use octane cache driver for other use cases, like using the control panel, serving the site etc. since this is techically not possible yet.

How to reproduce

Setup

• I've created a test repo with a minimum Statamic setup, see: https://github.com/o1y/statamic-antlers-octane
• My repo uses a custom Docker Image to add swoole support.
• Added "laravel/octane" to Statamic.
• Set CACHE_DRIVER: octane in .env
• Added a pages collection with 500 dummy entries. An entry contains random title and content.
• Added a custom route to web.php which renders sitemap.antlers.html to a filesitemap.xml:

{{ collection from="pages" as="posts" select="permalink" }}
    {{ posts }}
        {{ permalink }}
    {{ /posts }}
{{ /collection }}

Just run docker compose up in my test repos root to generate a static build. You'll find all files inside storage/app/static.

Result

Some generated pages are not having any title / content values.

The workaround is removing the select param from {{ collection from="pages" as="posts" select="permalink" }}. When removing the param the build created by ssg contains all expected values.
