### SUMMARY Refs #39890. First `useDeferredValue` adoption following the React 18 upgrade. Replaces the fixed-delay `useDebounceValue` with `useDeferredValue` in `TableExploreTree`'s schema browser search (the recently-debounced search from #39489). ### Why useDeferredValue is strictly better here - **No fixed timeout.** The deferred update runs as low-priority work and is automatically interrupted on each new keystroke, so the filter never lingers behind the input. - **Input stays responsive** because it reads `searchTerm` directly (line 472 of the file). The expensive tree-filter computation reads `deferredSearchTerm` instead. - **One fewer custom-hook dependency.** Uses the React primitive. The other `useDebounceValue` consumers in the codebase (SQL editor auto-save, SQL validation, JS editor parsing) debounce API calls or expensive parsing — not UI filtering — so they stay debounced. They're listed in #39890 for case-by-case follow-up but are not the same pattern. ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF No visual change. Behaviorally: typing into the schema-browser search field should feel snappier — the input never lags while the tree filter catches up, because React deprioritizes the filter under typing pressure. ### TESTING INSTRUCTIONS 1. Open SQL Lab and pick a database with many schemas/tables. 2. Type into the schema-browser search field rapidly. Input should feel responsive throughout. 3. Filter results should converge after you stop typing — same end state as before. 4. Clearing the field should restore the full tree. 5. `npm test -- --testPathPatterns='TableExploreTree'` — passes locally (11/11). ### ADDITIONAL INFORMATION - [x] Has associated issue: #39890 - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration - [ ] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
