Frontend performance: - Debounce DataGrid search (150ms) and replace O(n) row wrapping with index array - Replace QueryStore deep watcher with targeted field-level persistence snapshot - Extract shared nodeConfig computed in TreeItem (eliminates 15x redundant getConfig calls) - Clear tab result data on close to free memory - Add LRU eviction for completion caches (50 entry cap) - Replace savedSql version string join with numeric counter Memory leak fixes: - Store Tauri event unlisten handles and clean up on unmount - Clean up DataGrid search timer on unmount Backend security & resource management: - Add 50MB request body size limit - Reject file uploads >100MB and SQL files >200MB - Clean up SSE channels after transfer/import completes - Recover from poisoned mutex instead of panicking - Delete temporary upload files after preview - Validate SQL file paths to prevent directory traversal
