Manually sync items

Hello.

We have some custom code that assigns taxonomies to an attachment. After assigning the taxonomy we want to update the Algolia index.

At the moment we manually trigger do_action( 'attachment_updated') which then get’s picked up by the ‘sync_item’ function.

This isn’t very efficient, as we then see multiple individual batch API requests in Algolia, updating a single record at a time.

Is there anyway we can update multiple records at once, similar to how things run when triggering a manual re-index?

Saw there is the sync_term_posts function, could we use that, and is so would we need to instantiate a class to use it?

Thanks

Ian.
