For non-stored computed fields, `_modified_triggers` will traverse the tree (at the cost of extra queries) only to know which record to invalidate in cache. But in most cases, these fields have no data in cache, so they can be ignored from the start, which allows us to prune entire subtrees from the merged tree. By example: With simple write on `show_operations` of one `stock.picking.type`, the `_modified_triggers` will fetch every ids (from database) of `stock.picking` and `stock.move` related to this `stock.picking.type` (For `stock.move`, it is because of the `show_operations = fields.Boolean(related='picking_id.picking_type_id.show_operations'`)) In that case, there isn't any data of `show_operations` (`stock.move`) in cache, then there are nothing to invalidate and the `_modified_triggers` cost is high (extra queries/processing) for nothing. Then we cut parts of the tree when we know that they won't invalidate anything (=> if the cache is empty for the field). Also refactor the way to merge trees to be more efficient. Performance improvements: - For all tests at-install done by the runbot, we gain -+ 3.5% of queries. - In the example above, we reduce the number of queries (potentially bottleneck queries in large DB) from 7 to 4. - In term of CPU (without counting time in SQL), the new version is -+ 20 % faster (on install of stock,purchase,mrp and with --test-tags=/stock,/purchase). closes odoo/odoo#76322 task-2780812 closes odoo/odoo#99274 Related: odoo/enterprise#30951 Signed-off-by: Raphael Collet <rco@odoo.com>
