**Notes**: This driver delegates to a remote ObjectQL server, so it needs to serialize QueryAST over HTTP. The remote server must also support the new protocol.
321+
**Implementation Highlights**:
322+
1. **executeQuery()**: Sends QueryAST to /api/query endpoint with authentication
323+
2. **executeCommand()**: Unified interface for create/update/delete/bulk operations via /api/command
324+
3. **execute()**: Custom endpoint execution for workflows and specialized operations
325+
4. **Helper Methods**: getAuthHeaders(), handleHttpError(), retryWithBackoff(), buildEndpoint()
326+
5. **Authentication**: Support for Bearer token and API key authentication
327+
6. **Retry Logic**: Configurable retry with exponential backoff for network resilience
328+
7. **Logging**: Optional request/response logging for debugging
329+
8. **Config-based Constructor**: New SdkConfig interface for better configuration
330+

324+
325+
#### Methods
326+
327+
##### `executeQuery(ast: QueryAST, options?: any): Promise<{ value: any[]; count?: number }>`
328+
329+
Execute a query using QueryAST format (DriverInterface v4.0).
330+
331+
```typescript
332+
import { RemoteDriver } from '@objectql/sdk';
333+
334+
const driver = new RemoteDriver({
335+
baseUrl: 'http://localhost:3000',
336+
token: 'your-auth-token',
337+
enableRetry: true,
338+
maxRetries: 3
339+
});
340+
341+
// Execute a QueryAST
342+
const result = await driver.executeQuery({
343+
object: 'users',
344+
fields: ['name', 'email', 'status'],
345+
filters: {
346+
type: 'comparison',
347+
field: 'status',
348+
operator: '=',
349+
value: 'active'
350+
},
351+
sort: [{ field: 'created_at', order: 'desc' }],
352+
top: 10,
353+
skip: 0
354+
});
355+
356+
console.log(result.value); // Array of users
357+
console.log(result.count); // Total count
358+
```
359+
360+
##### `executeCommand(command: Command, options?: any): Promise<CommandResult>`
361+
362+
Execute a command for mutation operations (create, update, delete, bulk operations).
363+
364+
```typescript
365+
// Create a record
366+
const createResult = await driver.executeCommand({
367+
type: 'create',
368+
object: 'users',
369+
data: {
370+
name: 'Alice',
371+
email: 'alice@example.com',
372+
status: 'active'
373+
}
374+
});
375+
376+
console.log(createResult.success); // true
377+
console.log(createResult.data); // Created record
378+
console.log(createResult.affected); // 1
379+
380+
// Update a record
381+
const updateResult = await driver.executeCommand({
382+
type: 'update',
383+
object: 'users',
384+
id: 'user_123',
385+
data: { status: 'inactive' }
386+
});
387+
388+
// Delete a record
389+
const deleteResult = await driver.executeCommand({
390+
type: 'delete',
391+
object: 'users',
392+
id: 'user_123'
393+
});
394+
395+
// Bulk create
396+
const bulkCreateResult = await driver.executeCommand({
397+
type: 'bulkCreate',
398+
object: 'users',
399+
records: [
400+
{ name: 'Bob', email: 'bob@example.com' },
401+
{ name: 'Charlie', email: 'charlie@example.com' }
402+
]
403+
});
404+
405+
// Bulk update
406+
const bulkUpdateResult = await driver.executeCommand({
407+
type: 'bulkUpdate',
408+
object: 'users',
409+
updates: [
410+
{ id: 'user_1', data: { status: 'active' } },
411+
{ id: 'user_2', data: { status: 'inactive' } }
412+
]
413+
});
414+
415+
// Bulk delete
416+
const bulkDeleteResult = await driver.executeCommand({
417+
type: 'bulkDelete',
418+
object: 'users',
419+
ids: ['user_1', 'user_2', 'user_3']
420+
});
421+
```
422+
423+
##### `execute(endpoint?: string, payload?: any, options?: any): Promise<any>`
424+
425+
Execute a custom operation on the remote server.
426+
427+
```typescript
428+
// Execute a custom workflow
429+
const workflowResult = await driver.execute('/api/workflows/approve', {
430+
workflowId: 'wf_123',
431+
comment: 'Approved by manager'
432+
});
433+
434+
// Use default execute endpoint
435+
const customResult = await driver.execute(undefined, {
436+
action: 'calculateMetrics',
437+
params: { year: 2024, quarter: 'Q1' }
438+
});
439+
440+
// Call a custom action
441+
const actionResult = await driver.execute('/api/actions/send-email', {
442+
to: 'user@example.com',
443+
subject: 'Welcome',
444+
body: 'Welcome to our platform!'
445+
});
446+
```
447+
448+
#### Legacy CRUD Methods
449+
450+
The RemoteDriver also supports legacy CRUD methods for backward compatibility:
451+
452+
```typescript
453+
// Find records
454+
const users = await driver.find('users', {
455+
filters: [['status', '=', 'active']],
456+
sort: [['name', 'asc']],
457+
limit: 10
458+
});
459+
460+
// Find one record
461+
const user = await driver.findOne('users', 'user_123');
462+
463+
// Create a record
464+
const newUser = await driver.create('users', {
465+
name: 'Alice',
466+
email: 'alice@example.com'
467+
});
468+
469+
// Update a record
470+
const updated = await driver.update('users', 'user_123', {
471+
status: 'inactive'
472+
});
473+
474+
// Delete a record
475+
await driver.delete('users', 'user_123');
476+
477+
// Count records
478+
const count = await driver.count('users', {
479+
filters: [['status', '=', 'active']]
480+
});
481+
```
482+
483+
### Authentication Examples
484+
485+
```typescript
486+
// Bearer token authentication
487+
const driverWithToken = new RemoteDriver({
488+
baseUrl: 'http://localhost:3000',
489+
token: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...'
490+
});
491+
492+
// API key authentication
493+
const driverWithApiKey = new RemoteDriver({
494+
baseUrl: 'http://localhost:3000',
495+
apiKey: 'sk-1234567890abcdef'
496+
});
497+
498+
// Both token and API key
499+
const driverWithBoth = new RemoteDriver({
500+
baseUrl: 'http://localhost:3000',
501+
token: 'jwt-token',
502+
apiKey: 'api-key'
503+
});
504+
505+
// Custom headers
506+
const driverWithHeaders = new RemoteDriver({
507+
baseUrl: 'http://localhost:3000',
508+
headers: {
509+
'X-Tenant-ID': 'tenant_123',
510+
'X-Request-ID': crypto.randomUUID()
511+
}
512+
});
513+
```
514+
515+
### Error Handling and Retry
516+
517+
```typescript
518+
import { ObjectQLError, ApiErrorCode } from '@objectql/types';
519+
520+
// Enable retry with exponential backoff
521+
const driver = new RemoteDriver({
522+
baseUrl: 'http://localhost:3000',
523+
enableRetry: true,
524+
maxRetries: 3,
525+
timeout: 10000
526+
});
527+
528+
try {
529+
const result = await driver.executeQuery({ object: 'users' });
530+
} catch (error) {
531+
if (error instanceof ObjectQLError) {
532+
switch (error.code) {
533+
case ApiErrorCode.UNAUTHORIZED:
534+
console.error('Authentication required');
535+
break;
536+
case ApiErrorCode.VALIDATION_ERROR:
537+
console.error('Validation failed:', error.details);
538+
break;
539+
case ApiErrorCode.NOT_FOUND:
540+
console.error('Resource not found');
541+
break;
542+
default:
543+
console.error('API error:', error.message);
544+
}
545+
}
546+
}
547+
```
548+
549+
### Request Logging
550+
551+
```typescript
552+
// Enable logging for debugging
553+
const driver = new RemoteDriver({
554+
baseUrl: 'http://localhost:3000',
555+
enableLogging: true
556+
});
557+
558+
// Logs will be printed to console:
559+
// [RemoteDriver] executeQuery { endpoint: '...', ast: {...} }
560+
// [RemoteDriver] executeQuery response { value: [...], count: 10 }
561+
```
