Issue ----- Via the field prefetch mechanism, when we need a value of one field (not in cache of course), the ORM will prefetch all fields (which has the attribute to `prefetch=True`, the default value of this attribute is `True`) for all record ids in `_prefetch_ids`. Then, for each translate fields (where translate is not a callable) the ORM need to make a `LEFT JOIN` on the `ir_translation` to fetch the translated value. For big model, it leads to a simple `SELECT` with several `LEFT JOIN` on ir_translation but each LEFT JOIN have a cost in the planner time (a small cost in the execution time) of PostgreSQL. By example, for `product.template` (stock/sale/purchase installed), there are 6 LEFT JOIN to get all translated fields (5 of this fields are rarely used). Proposed solution ----------------- Deactivate the prefetch by default for all translate fields expect if this field is the `_rec_name` of the model (which is more likely to be used). In the example on the `product.template`: Without prefetching the translated fields, there is only one LEFT JOIN (the name, which is translated but is the `_rec_name` of the model). With the 6 translated fields to fetch, the query takes 5 ms to plan and 2 ms to execute VS with 1 translate field, it 1 ms to plan and 1.5 ms to execute. Side change note ---------------- - All translate of fields of `website.seo.metadata` should be prefetch to avoid lot of website errors (it is because, website put in cache data in sudo before reading it without sudo) - `description` (`mail.message.subtype`), `subject` (`mail.template`), `body_html` (`mail.template`) should be prefetch to avoid lot of extra query from mail module. - `vat_label` (`res.country`) should be prefetch to avoid a extra query for each website page. - Increase some queryCount (when it is legit, due to `subtitle` of `blog_post` or `description` of `event.type.ticket`, etc) task-2738029 closes odoo/odoo#82896 Signed-off-by: Raphael Collet <rco@odoo.com>
