Overview + +This implementation adds comprehensive async action support to Segment's destination actions framework, including full support for batch operations and proper state context integration. + +## โœ… Implemented Features + +### Core Async Support + +- **AsyncActionResponseType**: Single async operation response with context +- **AsyncPollResponseType**: Polling response for single operations +- **BatchAsyncActionResponseType**: Batch async operation response with multiple contexts +- **BatchAsyncPollResponseType**: Batch polling response with aggregated results + +### Action Interface Enhancements + +- Added `poll` method to ActionDefinition for single operation polling +- Added `pollBatch` method to ActionDefinition for batch operation polling +- Extended `ExecuteInput` to include `asyncContext` parameter +- Updated parseResponse to handle async responses correctly + +### Framework Integration + +- **Action Class**: Added `hasPollSupport` and `hasBatchPollSupport` properties +- **Action Class**: Added `executePoll` and `executePollBatch` methods +- **Destination Class**: Added `executePoll` and `executePollBatch` methods +- Full integration with existing error handling and validation + +### State Context Integration + +Actions can now use `stateContext` to persist operation data between calls: + +```typescript +perform: async (request, { settings, payload, stateContext }) => { + // Store operation context for later retrieval + if (stateContext && stateContext.setResponseContext) { + stateContext.setResponseContext('operation_id', operationId, { hour: 24 }) + } + + return { + isAsync: true, + asyncContext: { operation_id: operationId }, + message: 'Operation submitted', + status: 202 + } +} +``` + +### Batch Operations Support + +Full support for APIs that return multiple operation IDs: + +```typescript +performBatch: async (request, { settings, payload }) => { + const response = await request('/operations/batch', { + json: { operations: payload } + }) + + if (response.data?.operation_ids) { + return { + isAsync: true, + asyncContexts: response.data.operation_ids.map((id, index) => ({ + operation_id: id, + batch_index: index, + user_id: payload[index]?.user_id + })), + message: `${response.data.operation_ids.length} operations submitted`, + status: 202 + } + } +} +``` + +### Batch Polling + +Comprehensive batch polling with individual operation tracking: + +```typescript +pollBatch: async (request, { settings, asyncContext }) => { + const contexts = asyncContext?.asyncContexts || [] + const results = [] + + // Poll each operation individually + for (const context of contexts) { + const result = await pollSingleOperation(context.operation_id) + results.push(result) + } + + // Aggregate results + return { + results, + overallStatus: determineOverallStatus(results), + shouldContinuePolling: results.some((r) => r.shouldContinuePolling), + message: generateSummaryMessage(results) + } +} +``` + +## ๐Ÿ“ File Structure

async operations with context preservation +- โœ… Batch async operations with multiple operation IDs +- โœ… Error handling for missing contexts +- โœ… State context integration (when available) + +## ๐Ÿ”„ Usage Examples + +### Single Async Operation + +```typescript +// Submit +const result = await destination.executeAction('myAction', { event, mapping, settings }) +if (result.isAsync) { + const operationId = result.asyncContext.operation_id + // Poll later... +} + +// Poll +const pollResult = await destination.executePoll('myAction', { + event, + mapping, + settings, + asyncContext: { operation_id: 'op_123' } +}) +``` + +### Batch Async Operation + +```typescript +// Submit batch +const result = await destination.executeBatch('myAction', { events, mapping, settings }) +if (result.isAsync) { + const operationIds = result.asyncContexts.map((ctx) => ctx.operation_id) + // Poll later... +} + +// Poll batch +const pollResult = await destination.executePollBatch('myAction', { + events, + mapping, + settings, + asyncContext: { asyncContexts: result.asyncContexts } +}) +``` + +## ๐ŸŽฏ Key Benefits + +1. **Full Backward Compatibility**: Existing synchronous actions continue to work unchanged +2. **Comprehensive Batch Support**: Handle APIs returning multiple operation IDs +3. **State Context Integration**: Leverage existing state persistence mechanisms +4. **Type Safety**: Full TypeScript support for all async operations +5. **Error Handling**: Robust error handling for network issues, missing contexts, etc. +6. **Flexible Polling**: Support both individual and batch polling strategies +7. **Framework Integration**: Seamlessly integrates with existing action framework + +## ๐Ÿ”ฎ Future Enhancements + +- Automatic retry logic with exponential backoff +- Built-in timeout management for long-running operations +- Concurrent batch polling with configurable limits +- Enhanced test framework support for async responses +- Metrics and monitoring for async operation performance + +## ๐Ÿš€ Ready for Production + +This implementation is production-ready and provides a solid foundation for handling asynchronous operations in destination actions while maintaining full compatibility with existing synchronous workflows. diff --git a/packages/core/src/destination-kit/action.ts b/packages/core/src/destination-kit/action.ts index

Executing Async Operations - -**Initial Submission:** - -```typescript -const result = await destination.executeAction('myAction', { - event, - mapping, - settings -}) - -// Check if it's an async operation -if (result.isAsync) { - // Operation context is automatically stored in stateContext - // No need to manually handle context - polling will retrieve from stateContext -} -``` - -**Polling for Status:** - -```typescript -const pollResult = await destination.executePoll('myAction', { - event, - mapping, - settings - // stateContext is automatically passed - no need to specify async context -}) - -// Check overall status and individual results -if (pollResult.overallStatus === 'completed') { - console.log('All operations completed') - pollResult.results.forEach((result, index) => { - console.log(`Operation ${index}:`, result.result) - }) -} else if (pollResult.overallStatus === 'failed') { - console.error('Some operations failed') - pollResult.results.forEach((result, index) => { - if (result.status === 'failed') { - console.error(`Operation ${index} failed:`, result.error) - } - }) -} else if (pollResult.shouldContinuePolling) { - // Schedule another poll - setTimeout(() => poll(), 5000) -} -``` - -## Framework Integration - -### Action Class Changes - -The `Action` class now includes: - -- `hasPollSupport: boolean` - indicates if the action supports polling -- `executePoll()` method - executes the poll operation - -### Destination Class Changes - -The `Destination` class now includes: - -- `executePoll()` method - executes polling for a specific action - -## Error Handling - -Async actions should handle several error scenarios: - -1. **Missing Async Context:** When poll is called without required context data -2. **Invalid Operation ID:** When the operation ID is not found -3. **Network Errors:** When polling requests fail -4. **Timeout:** When operations take too long - -## Best Practices - -1. **Always validate async context** in the poll method -2. **Include meaningful progress indicators** when possible -3. **Set appropriate polling intervals** to avoid overwhelming the destination API -4. **Handle all possible operation states** (pending, completed, failed, unknown) -5. **Provide clear error messages** for debugging -6. **Store minimal context** needed for polling to reduce memory usage - -## Testing - -Testing async actions requires special consideration: - -```typescript -describe('Async Action', () => { - it('should handle async operations', async () => { - // Test that async operations return proper async response - const responses = await testDestination.testAction('asyncOperation', { - event, - mapping, - settings - }) - - // Verify the destination API was called correctly - expect(responses[0].data.status).toBe('accepted') - expect(responses[0].data.operation_id).toBeDefined() - }) - - // Note: Direct poll testing requires calling the poll method directly - // as the test framework doesn't support async response handling yet -}) -``` - -## Example Implementation - -See `/packages/destination-actions/src/destinations/example-async/` for a complete working example of an async action implementation. - -## Future Enhancements - -1. **Automatic Polling:** Framework could handle polling automatically -2. **Exponential Backoff:** Built-in retry logic with backoff -3. **Timeout Management:** Automatic timeout handling -4. **Test Framework Integration:** Better support for testing async responses -5. **Enhanced Error Recovery:** Smarter retry logic for failed operations - -## Migration Guide - -To add async support to an existing destination: - -1.
