-----------------------------------
Parent: (was: ATLAS-5349)
Issue Type: Task (was: Sub-task)
> Atlas UI: Defer non-critical API calls and deduplicate Redux fetches on
> Search load
> -----------------------------------------------------------------------------------
>
> Key: ATLAS-5394
> URL: https://issues.apache.org/jira/browse/ATLAS-5394
> Project: Atlas
> Issue Type: Task
> Components: atlas-webui
> Affects Versions: 3.0.0
> Reporter: Prasad P. Pawar
> Assignee: Prasad P. Pawar
> Priority: Major
>
> Search page fires 65 requests (~4.8 MB) on load. Many are unnecessary for the
> initial view.
> Duplicate / premature API calls:
> - RecentActivity: 6 parallel /admin/audits calls on mount (only 1 tab visible)
> - fetchTypeHeaderData: dispatched from Sidebar, Dashboard, EntitiesTree (2+
> duplicate typedefs/headers ~32 KB each)
> - fetchEntityData: typedefs?type=entity (~391 KB) on mount — sidebar only
> needs counts initially
> - All sidebar trees (entities, classifications, enums, glossary) mount and
> fetch on load even when collapsed
> Fixes:
> 1. RecentActivity — fetch active tab only on mount; fetch other tabs on
> click; cache visited tabs
> 2. typeDefHeaderSlice — skip fetch if data exists and not stale; single
> dispatch from Layout/bootstrap
> 3. EntitiesTree — remove mount-time fetchEntityData(); use typeHeaderData +
> metrics for initial tree; fetch full typedef only on expand
> 4. SideBarBody — lazy-mount tree components when accordion section expands
> (React.lazy + Suspense + skeleton)
> 5. API priority tiers: Tier 1 (session + headers) → Tier 2 (metrics) → Tier 3
> (audits/glossary via requestIdleCallback)
> 6. AbortController on route unmount for in-flight non-critical requests
> Acceptance Criteria:
> * Network tab: 1 audit call on search landing (not 6–7)
> * Exactly 1 typedefs/headers request on search load
> * No typedefs?type=entity on initial load unless Entities section expanded
> * Collapsed sidebar sections do not trigger typedef API calls
> * Initial load requests < 45 (from 65)
> * Unit tests for deferred fetch, dedup, and tab-click behavior
