- batch_operations.rs: replace join_all with buffer_unordered, Arc<str> for shared IDs, remove redundant clones and dead Semaphore
- folder_db_repository.rs: use COUNT(*) OVER() for single-query pagination; UPDATE RETURNING for rename/move (eliminates extra SELECTs)
- folder_service.rs: remove StorageTransaction wrapper from rename/move — direct repo call (4→2 and 5→3 queries)
- search_service.rs: replace sort_by(to_lowercase) with sort_by_cached_key (N vs 2·N·log₂N allocations)
- image_transcode_service.rs: dynamic rayon pool sizing via available_parallelism() instead of hardcoded 2 threads
- Remove dead transactions module (zero consumers after folder_service refactor)
- Change SearchUseCase::search() return type to Arc<SearchResultsDto>
- Replace Cache<u64, SearchResultsDto> with Cache<u64, Arc<SearchResultsDto>>
- Eliminate .clone() on full result set; use Arc::clone() (ptr bump)
- Remove Clone derive from SearchResultsDto (no longer needed)
- Update handlers to deref Arc for JSON serialization
sync::Cache uses an internal Mutex that blocks the Tokio worker thread
during maintenance (eviction, frequency bookkeeping). Under high
concurrency this serialises all tasks scheduled on the same worker.
future::Cache defers maintenance to an internal async task and never
holds a synchronous lock visible to the caller.
Changes:
- Field type: sync::Cache → future::Cache
- get_from_cache / store_in_cache: now async, calls .await
- clear_search_cache: added run_pending_tasks().await after invalidate
Consistent with the pattern already used in thumbnail_service,
image_transcode_service, and file_content_cache.
- Add search_files_paginated method to FileReadPort for database-level pagination
- Implement efficient SQL-based search with LIMIT/OFFSET in file_blob_read_repository
- Add relevance scoring (exact match > starts-with > contains)
- Support multiple sort options (name, date, size) with ascending/descending order
- Fix cache expiration handling with proper borrow checker semantics
- Use i64 for SQL LIMIT/OFFSET parameters instead of usize
- Clean up duplicate SQL query builder code in search_files_paginated
This significantly improves search performance for non-recursive queries by:
- Pushing pagination to the database layer
- Avoiding loading all files into memory for filtering
- Supporting database-level sorting
Run `cargo fmt` across all Rust source files to enforce consistent
formatting (import ordering, line wrapping, match arm braces).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Standardize code formatting across all 173 Rust source files
using rustfmt. No functional changes - purely cosmetic.
This establishes a consistent code style baseline for the
project going forward.
