Summary

This PR updates the Nightingale frontend to support Apache IoTDB 2.x table-model SQL queries with datasource-level and per-query database selection.

It is the frontend part of the migration described in #3374, and works together with the backend implementation in #3375.

Changes

  • Add IoTDB RPC settings to the datasource form and detail page:
    • RPC address
    • Default database
    • RPC connection timeout
    • RPC query timeout
  • Add an optional database field to dashboard, Query Explorer, and alert rule queries.
  • Pass the selected database through graph, table, and alert query requests.
  • Use the datasource default database when no per-query database is specified.
  • Support valueKey for IoTDB table-model query results, with fallback to the legacy metricKey field for compatibility.
  • Expand dashboard template variables before sending IoTDB queries.
  • Refresh query results when the selected database or other query parameters change.

Compatibility

Existing IoTDB dashboards and queries remain compatible. Queries that do not specify a database continue to use the datasource default database, and older payloads using metricKey are still accepted.

📝 Walkthrough

Walkthrough

IoTDB datasource settings now include RPC and Table Model fields. Dashboard, Explorer, and alert queries support optional database selection, template replacement, shared value-key normalization, and refresh triggers for changed query inputs.

Changes

IoTDB datasource configuration and query flows

Layer / File(s) Summary
Datasource settings and request contracts
src/pages/datasource/Datasources/iotdb/*.tsx, src/plugins/iotdb/services.ts
The datasource form and detail page expose RPC address, default database, connection timeout, and query timeout. IoTDB request types accept optional database and key fields.
Dashboard query resolution
src/plugins/iotdb/Dashboard/QueryBuilder.tsx, src/plugins/iotdb/Dashboard/datasource.tsx
The dashboard query builder captures an optional database and requires query text. Dashboard requests replace template variables and send the resolved query, database, and normalized value key.
Explorer database selection
src/plugins/iotdb/Explorer/QueryBuilder.tsx, src/plugins/iotdb/Explorer/Graph.tsx, src/plugins/iotdb/Explorer/Table.tsx
Explorer views capture the database, include it in graph and log requests, and re-run queries when it changes.
Alert query preview
src/plugins/iotdb/AlertRule/Queries/index.tsx, src/plugins/iotdb/AlertRule/Queries/GraphPreview.tsx
Alert queries capture an optional database. Graph previews use shared value-key normalization and fetch through the visibility effect.
Value-key normalization and tests
src/plugins/iotdb/utils.ts, src/plugins/iotdb/utils.test.ts
The shared helper normalizes value keys, falls back to metric keys, and has coverage for fallback, precedence, array, string, and empty inputs.

Use Tailwind for the new layout additions.

The three additions introduce Ant Design Row/Col wrappers or inline layout styles instead of Tailwind utilities. This creates mixed layout ownership in the changed UI.

  • src/pages/datasource/Datasources/iotdb/Form.tsx#L41-L42: replace the new Row/Col wrappers and inline width styles with Tailwind utilities.
  • src/plugins/iotdb/Dashboard/QueryBuilder.tsx#L108-L110: replace the new database Row/Col wrapper with Tailwind layout utilities.
  • src/plugins/iotdb/AlertRule/Queries/index.tsx#L106-L109: replace the new fixed-width Col with Tailwind utilities or the existing shared layout abstraction.

As per coding guidelines, use Tailwind utility classes for container layout and component-local display styles.

- Around line 55-61: Update the timeout Form.Item rules for
settings['iotdb.dial_timeout'] and settings['iotdb.timeout'] to reject cleared
values by requiring positive numbers, or explicitly remove empty values before
persistence and preserve backend defaults. Add form coverage that clears and
submits each timeout field, verifying the chosen behavior.

In `@src/plugins/iotdb/AlertRule/Queries/GraphPreview.tsx`:
- Around line 54-56: Update the valueKey construction in the query mapping so an
empty valueKey array is treated as missing and falls back to metricKey. Use
Array.isArray, normalize the joined value before applying the fallback, and
preserve correct handling for undefined, strings, and non-empty arrays.
- Line 91: Update the preview-opening button handler to stop calling fetchData
directly when setting visible to true, allowing the visibility effect to perform
the single request; add a test covering preview opening and assert that
getDsQuery is called exactly once.

In `@src/plugins/iotdb/Dashboard/datasource.tsx`:
- Line 55: Update the valueKey selection in
src/plugins/iotdb/Dashboard/datasource.tsx at line 55 and
src/plugins/iotdb/Explorer/Graph.tsx at line 75 so an empty valueKey array does
not win the fallback; select valueKey only when it is non-empty, otherwise use
metricKey before applying _.join.

Treat an empty valueKey array as missing.

When q.keys.valueKey is [], _.join([], ' ') returns '', so the metricKey fallback is skipped and the request sends no value key. Normalize the joined value before applying the fallback, use Array.isArray, and test undefined, empty-array, string, and non-empty-array inputs.

Use a Tailwind width utility.

Replace the inline width style with className='w-full'.

Proposed change
-              <InputNumber style={{ width: '100%' }} controls={false} />
+              <InputNumber className='w-full' controls={false} />

As per coding guidelines, use Tailwind utility classes for component-specific display styles.
