- Leave the query to WordPress on OR, nested groups with registered keys, several post types, orderby on a named routed clause, and compare/type pairs whose flat-column semantics differ from native (untyped numeric ranges, CHAR on decimals, NUMERIC on text) - Wrap LIKE values as %esc_like%; hook pre_get_posts at priority 1000 so plugin clauses (HivePress) are seen - Verify: wp eval-file tests/live/run.php router (7/7); qbench Q04/Q06/Q08/Q14/Q16 == native on dev36 - PR: PR-060

/**
|
|
* TMDO_Post_Query_Router — Post entity meta_query → flat table JOIN rewriter (v2.10.1).
|
|
*
|
|
* Companion to legacy TMDO_Query_Router (which targets zone hot tables).
|
|
* Independent class — does NOT modify the user side path or the legacy zone
|
|
* router. Both routers can coexist on the same WP_Query without conflict
|
|
* because they extract clauses on disjoint criteria:
|
|
*
|
|
* - TMDO_Query_Router → only zone-registered keys with feature_flag query_active
|
|
* - TMDO_Post_Query_Router → only entity-registered keys with mode=reads_from_flat
|
|
*
|
|
* Mode-gated: only rewrites when post mode is `shadow_read` or `aeav_only`.
|
|
* In `disabled` / `dual_write` modes the router is a no-op.
|
|
*
|
|
* Hook order:
|
|
* 1. pre_get_posts — strip registered keys from meta_query, store in
|
|
* $query->set( 'wpdo_post_clauses', $routed )
|
|
* 2. posts_join — LEFT JOIN wp_wpdo_post_<group> per routed post_type
|
|
* 3. posts_where — append WHERE conditions targeting flat columns
|
|
* 4. posts_groupby — ensure GROUP BY posts.ID to dedup join multiplication
|
|
*
|
|
* Status / date on the flat table (O-1): when the group's post_status /
|
|
* post_date copies are ready (TMDO_Post_Status_Sync) and none is missing,
|
|
* a single-post-type search with explicit statuses and date ordering
|
|
* INNER JOINs the table, filters the copies, orders by the copied
|
|
* post_date and skips GROUP BY (one row per post), so MySQL can walk
|
|
* `idx_post_status_date` and stop at the LIMIT.
|
|
*
|
|
* Found rows (O-4): routed searches drop SQL_CALC_FOUND_ROWS (it counts every
|
|
* match inside the page query); found_posts_query answers from a COUNT of the
|
|
* same query, kept in the object cache until posts' last_changed moves (core
|
|
* post saves, and flat writes via TMDO_Hook_Bus).
|
|
*
|
|
* 🔒 v2.9.x → v2.10.x frozen contract: never touches user entity. Routes
|
|
* only entity_type='post'.

*
