Status & Next Steps

Current Status: Phase 2 in progress - Advanced features being implemented

Completed:

  • ✅ Phase 0: Architecture & Setup
  • ✅ Phase 1: MVP Development (Connection management, SQL editor, schema browser, table editor)
  • ✅ Milestone 2.1-2.5: MySQL/MongoDB drivers, autocomplete, table editing, SQL import/export
  • ✅ Milestone 2.6: Query Plan Visualizer (2025-11-21)
  • ✅ Milestone 2.7: ER Diagram Generator (2025-11-20)
  • ✅ Milestone 2.9: Router Migration with TanStack Router (2025-11-21)
  • ✅ Settings & Configuration (2025-11-20)
  • ✅ Native Window & System Tray (2025-11-21)
  • Custom Window Titlebar & Menu System (2025-11-21)
  • Global Keyboard Shortcuts System (2025-11-21)
  • Window State Persistence (2025-11-21)

Recently Completed:

  • Multi-Window Support — Multiple independent OS windows, each with its own connection. Single Rust process / shared AppState (connections keyed by ID → no cross-window collision; keyring shared & safe). Rust-side window creation in commands/window.rs (open_database_window, unique win-{uuid} label, chrome mirrors main); one-shot PendingWindowProfiles map + take_pending_window_profile drives per-window auto-connect. Affordances: home-screen "Open in New Window" per profile, titlebar File → New Window, tray "New Window", global ⌘⇧N / Ctrl+⇧N. Capability widened to win-*; windowState.ts geometry keyed per window label (legacy key kept for main). (2026-05-17)
  • Performance Hardening Pass — Audit-driven backend/frontend optimizations: 50k row cap on execute_query (+truncated flag/toast); get_autocomplete_metadata N×M sequential awaits → tokio::task::JoinSet bounded at 16; SQLite get_tables/get_foreign_keys and PostgreSQL zero-count N+1 collapsed into single round-trips; PostgresDriver moved to a deadpool-postgres pool (max 8); export_query_logs writes off-runtime via spawn_blocking; ActivityMonitor metadata refetch decoupled from pagination; Vite manualChunks vendor splitting; TableInspector keyset pagination (single-PK/non-Mongo) with OFFSET fallback, backed by a hardened filter/sort-aware get_table_data_keyset (fixed an invalid-SQL cursor-literal bug). Also restored the cargo test --lib target (was uncompilable due to State::from in schema.rs tests; now uses tauri::test::mock_app() — 118 tests run, 115 pass, 3 keyring failures environmental). (2026-05-17)
  • Backup Manager UI<BackupManagerDialog> over the existing backup commands. Titlebar View-menu entry via useAppModal ("backup", rendered in GlobalModals). Directory header (Open Folder/Refresh), create panel (schema/data toggles, note, slow-op loading), backups table with per-row Restore (destructive confirm + drop-existing checkbox) and Delete. (2026-05-17)
  • Redis Key Browser (left sidebar) — For Redis connections SchemaExplorer renders <RedisSchemaTree> instead of the relational tree: five key-type groups lazy-loaded via type-filtered SCAN … TYPE, search-box glob, "Load more…". Clicking a key opens <RedisValuePanel> in a main-area tab (new "redis" TabContext type, rediskey- tab id). Replaced the earlier titlebar-menu /redis-keys two-pane browser. (2026-05-17)
  • Foreign-Key Drill-Down — Table Inspector FK cells expose an external-link button + "Open Referenced Record" context entry; opens the referenced table in a new tab pre-filtered to the related row via a self-describing tablefk- tab id (URL-sync recreation rebuilds schema/table/column/value + filter). (2026-05-17)
  • Redis DriverDbDriver::Redis variant with redis crate 0.27. MultiplexedConnection via Arc<Mutex<...>>. Key-type pseudo-tables (strings/hashes/lists/sets/zsets) via SCAN sampling. Raw Redis command execution (GET, SET, HGETALL, etc.). Wired into test_connection_command + connect_to_database. Default port 6379. (2026-05-15)
  • Visual Schema Designer — ReactFlow 3-panel drag-and-drop schema builder. Custom TableSchemaNode with column display (PK/UNQ/NN badges). Right-panel properties editor for table name, schema, 12 column types, FK references. FK edges auto-drawn between nodes. "Preview SQL" via preview_create_table + "Create Tables" via create_table. Route /_connected/visual-schema-designer, accessible from titlebar. (2026-05-15)
  • Backup Managercommands/backup.rs with 6 commands: get_backup_directory, list_backups, create_backup (pg_dump / mysqldump / sqlite copy / mongodump subprocess), restore_backup (psql / mysql / sqlite copy), delete_backup, open_backup_directory. Data models in models/backup.rs (BackupEntry, BackupOptions, BackupStatus, RestoreOptions, BackupProgress). (2026-05-15)
  • Stored Procedures & Functions Viewer — New commands list_procedures, get_procedure_definition, execute_procedure (PG via pg_proc + pg_get_functiondef, MySQL via information_schema.ROUTINES + SHOW CREATE, SQL Server via sys.objects). <StoredProceduresPanel> lazy-loads definitions and offers an execute dialog with JSON args (2026-04-21)
  • Write-Query Guards (dbpro parity) — Pre-execute analyzer intercepts destructive SQL (DELETE/UPDATE without WHERE, DROP/TRUNCATE/DROP COLUMN); <DestructiveQueryGuard> AlertDialog; wired through _connected/query.tsx so Ctrl+Enter is also guarded; respects settings.query.confirmDestructive (2026-04-21)
  • Query Folders (dbpro parity) — Nested SnippetFolder tree in SnippetSidebar with context-menu create/rename/delete/move, cycle prevention, cascade-delete-to-root, search auto-expand; persisted separately from snippets for backward compat (2026-04-21)
  • OpenRouter AI Provider (dbpro parity) — New provider routing through OpenAI-compatible openrouter.ai/api/v1 with FQID models like anthropic/claude-3.5-sonnet; settings entry in AiAssistant (2026-04-21)
  • Turso / libSQL Driver — New DbDriver::Turso variant using libsql crate 0.9. Remote mode with auth-token auth. Routes through SqliteDdlGenerator for DDL and migrations. Form adapts for URL host + "Auth Token" field (2026-04-21)
  • Schema Migration Toolssrc-tauri/src/migrations/ module with pure diff algorithm + driver-aware SQL generator. Tauri commands compute_schema_diff, generate_migration, apply_migration. <MigrationsDialog> 3-step flow wired to command palette (2026-04-21)
  • Activity Monitor — Live Process List + Server Metricsget_active_queries, kill_query, get_server_stats commands; PG via pg_stat_activity/pg_stat_database, MySQL via PROCESSLIST/SHOW GLOBAL STATUS; <ProcessList> (2s polling, per-row cancel) + <ServerMetricsChart> (60-sample rolling recharts) (2026-04-21)
  • Schema Management Deferred Items<TableEditDialog> for existing tables (add/rename/drop columns, toggle nullability, SQL preview); <ConfirmDestructiveDialog> with FK dependency listing + auto-CASCADE; useMetadataCache hook + metadata-changed CustomEvent; new "Schema" menu in titlebar (2026-04-21)
  • Supabase + Neon Drivers — New DbDriver::Supabase and DbDriver::Neon variants route through the existing PostgreSQL driver. Added TLS support: native-tls + postgres-native-tls crates, ConnectionOptions.require_tls flag, auto-enabled for Supabase/Neon and when ssl_mode == Require. Frontend picker tiles activated, driver-specific connection-string placeholders added (Milestone 3.13 partial) (2026-04-21)
  • v0.19.2 Bug Fixes — PostgreSQL connection password retrieval resilience (keyring fallback in connect_to_database, session cache in save_password) + pgvector/array type rendering: vector columns now deserialise correctly via the pgvector crate and all PostgreSQL array types (_float4, _int4, _text, etc.) emit JSON arrays instead of NULL (2026-03-10)
