"Language Overlay - How it works"

on YouTube ↗44m

" summary

Explains that TYPO3 implements overlays by loading the default record (language uid 0) then merging a translation row, replacing every field except uid and keeping the pointer in overlay_uid, enabling strict, fallback or free modes; versions use workspace id and version state so previews create extra rows rather than full copies. Recommends using PageRepository for correct language+workspace resolution. Recent work moves merging into the database with Common Table Expressions to reduce PHP hops while preserving sort order and many-language support.
