Korean README

Drift ORM implementation of CheckpointStore for durable_workflow.

Features

• Type-safe queries via Drift's query builder and code generation
• Reactive streams — watchExecution(), watchExecutionsByStatus(), watchCheckpoints() for real-time UI updates
• Automatic schema migration via Drift's built-in migration system
• Same schema as durable_workflow_sqlite — same 5 tables, same indexes, same PRAGMA configuration
• Flutter-ready — works with sqlite3_flutter_libs for mobile/desktop

Usage

import 'package:drift/native.dart';
import 'package:durable_workflow_drift/durable_workflow_drift.dart';

// Open database
final db = DurableWorkflowDatabase(NativeDatabase.createInBackground('workflow.db'));
final store = DriftCheckpointStore(db);

// Use with DurableEngine
final engine = DurableEngineImpl(store: store);

// Drift-specific: reactive queries
store.watchExecution('exec-1').listen((execution) {
  print('Status: ${execution?.status}');
});
