New query, data and schema tools for the Database feature (SQLite, PostgreSQL, MySQL). ## Query console - **Explain Plan** tab: SQLite `EXPLAIN QUERY PLAN`, PostgreSQL `EXPLAIN (FORMAT JSON)`, MySQL `EXPLAIN`, parsed in `ide-db::plan` into an operation tree (Full Scan / Index Scan / Group By / Order By …) under a statement root, with a properties panel. - **Query history**: `ide-db::history` keeps executed statements per project and source in `db-history.json` (deduplicated, newest first, 500 max). The Browse Query History dialog has search, a highlighted preview, Paste and Delete. - Output reports `(execution: X ms, fetching: Y ms)`. ## Results and table editor - Local column filter (value list with counts) and local sort. - Record / Value / Aggregates side panel. - Chart view (bar / line) with X / Y / aggregation settings. - Export Data dialog: extractor, Transpose, headers, preview, file or clipboard. An extractor drop-down sits on the data toolbars. - Import Data from a CSV / TSV file. - Table editor gets a WHERE | ORDER BY row. Column headers fit their names, with filter and sort indicators. Whole SQLite REALs display as `3108`, not `3108.0`. ## Database tree - Triggers under tables. Routines, sequences and materialized views under schemas, with DDL, Quick Documentation and Drop. - Data source options: object filter, show template databases, single database mode (PostgreSQL). - New ▸ Import from Clipboard (connection URLs). ## IPC New commands: `db_schema_objects`, `db_object_ddl`, `db_explain`, `db_history`, `db_remove_history`. Bindings are regenerated. ## Testing - `cargo test -p ide-db`: plan parsing, history store, trigger listing and DDL, explain without executing. - `cargo clippy -p ide-db -p openidea --all-targets -- -D warnings` is clean. - `pnpm typecheck` and eslint pass. `pnpm vitest run src/features/database src/ui`: 226 passed. - Checked in the running app against a SQLite database: - tree with triggers - result grid, local filter, side panel - chart - Explain Plan - history dialog - Export Data dialog - table editor ORDER BY - CSV import Merge follow-up: grouped the new `--chart-series` token under a section comment and added it to the theme plugin template (theme.test.ts on main), regenerated docs/plugins/themes.md. Re-verified after merging main on macOS with a SQLite source: query + result grid with filter/sort headers, Explain Plan tab (Full Scan / Index Scan / Group By / Order By), Query History dialog; `cargo nextest run -p ide-db` 45 passed, bindings unchanged after regeneration. https://claude.ai/code/session_01VUYsdXA2nkF5v6zsC93dpn

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
