perf(detail/header): lazy + dedupe related-list fan-out, coalesce header polls by xuyushun441-sys · Pull Request #1477 · objectstack-ai/objectui

xuyushun441-sys · 2026-06-04T07:07:51Z

Problem

Opening a record detail (e.g. an environment in the cloud control plane) fired ~50 concurrent /api/v1 requests that head-of-line-blocked one another on the single control-plane container, making the page feel slow.

Root causes (fixed at source)

RecordDetailView eagerly preloaded every reverse-reference child even when the reference rail renders them (≥2 related lists) — that data was then discarded (the Related tab is hidden in that layout) while the rail re-fetched the same collections. Now skips the preload when the rail owns the related lists.
record-reference-rail fetched every collection eagerly on mount, once per re-render. Now it (a) gates fetching on visibility via IntersectionObserver (the rail is hidden xl:flex), (b) caps concurrency at 3, and (c) fetches once per (parentId + entries) via a signature guard, applying results through a mounted-ref so a fetch that outlives a re-render isn't dropped.
AppHeader inbox/notification, approvals, and activity pollers re-ran several times during bootstrap (deps settling), each firing an immediate fetch. Added in-flight guards so the bootstrap re-runs coalesce to one request; results apply via a mounted ref.
The approvals poll now issues a single request with all identities comma-joined (pairs with the framework multi-approverId change) instead of one request per identity.

Verification

Local rig (Vite live source against the cloud control-plane), opening an environment detail:

total /api/v1 requests on open: ~52 → ~17
related collections: ×3–5 each → ×1
approvals/requests: ×9 → ≤3

Typecheck clean; plugin-detail (117) and app-shell (243) test suites pass.

Deploy note

The approvals client change pairs with the framework multi-approverId endpoint — bump the cloud .framework-sha and .objectui-sha together.

…der polls Opening a record detail fired ~50 concurrent /api/v1 requests that head-of-line-blocked one another on the single control-plane container. Root causes, fixed at source: - RecordDetailView eagerly preloaded EVERY reverse-reference child even when the reference rail renders them (≥2 related lists) — that data was then discarded (the Related tab is hidden in that layout) while the rail re-fetched the same collections. Skip the preload when the rail owns the related lists. - The reference rail fetched every collection eagerly on mount, once per re-render. Now it (a) gates fetching on visibility via IntersectionObserver (the rail is `hidden xl:flex`), (b) caps concurrency at 3, and (c) fetches once per (parentId + entries) via a signature guard, applying results through a mounted-ref so a fetch that outlives a re-render isn't dropped. - AppHeader inbox/notification, approvals, and activity pollers re-ran several times during bootstrap (deps settling), each firing an immediate fetch — inbox/receipt ×5, activity ×3+. Added in-flight guards so the bootstrap re-runs coalesce to one request; results apply via a mounted ref. - The approvals poll now issues a single request with all identities comma-joined (pairs with the framework multi-approverId change) instead of one request per identity. Verified locally (Vite live source, cloud control-plane): opening an environment detail dropped from ~52 to ~17 requests, related collections from ×3–5 each to ×1, approvals from ×9 to ≤3.
