Triples size sweep improvements - #2862

📝 WalkthroughWalkthroughThe collector now processes ordered update batches, excludes orphaned records from aggregation, tracks consecutive loop-limit hits across scheduled runs, and alerts production after a configured threshold. ChangesTriples size collection
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: ⚪ Minimal · up to The change improves deletion ordering and work detection for the update queue; no actionable merge-blocking risk remains after normal checks and review. Sequence Diagram(s)sequenceDiagram

- Around line 78-82: Update the clean-drain check around collect-batch! to use
the number of selected or deleted queue rows rather than the outer INSERT
update-count, so orphan-only batches are treated as non-empty. Add an
integration test covering an orphan-only batch followed by pending valid
triples_size_updates rows, verifying the valid updates are processed afterward.

- Around line 74-84: Update the loops = max-loops handling around
consecutive-limit-hits to check whether queue rows remain before counting a
limit hit. Reset consecutive-limit-hits when the final allowed batch drains the
queue, while preserving the existing alert behavior for remaining rows. Add a
regression test covering one queued row with max-loops set to 1.

insert-orphan-rows!stores rows under a different random app ID, but the test only queries the real app ID. The assertions at Lines 290-293 prove that the valid row was processed, but not that the orphan rows were removed. Return the orphan app ID or inserted row IDs, then assert that their queue is empty after collection.

Orders the
triples_size_updatestable by id when we claim the updates to delete. Right now it's doing a seq scan and it spends a lot of time going over dead tuples.Also fixes a bug where we were looking at the number of aggregates we updated instead of the number of
triples_size_updatesrows we deleted when we determined if we had done any work. If we were processing a ton of rows for a deleted app, we would have stopped early.Only alerts us if we exceed the loop limit 10 times in a row.
