Add PreparableLazyBuilderInterface and allow controllers to implement it

Created on 27 August 2015, almost 10 years ago

Problem/Motivation

Consider a page with 300 comments and have 300 placeholder-ed action links within the comment that are different per user.

All those action links need the entity loaded.

So the code flow for rendering the 300 comments is:

    $comments = Comment::load($all_300_entities);

While for the placeholders with lazy builders the code flow is for each:

  $comment = Comment::load($cid);

Proposed resolution

The idea is to allow for groups of data to load all of them at once.

e.g. if a lazy builder for a placeholder implements PreparableLazyBuilderInterface then its prepare method is called with all placeholders in that 'group'.

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!
