BaseSync efficiently handles large datasets with 100,000+ rows through optimized bulk operations.\n\n## ✨ Features\n\n- **Bidirectional Synchronization**: Pull from remote to local, then push from local to remote\n- **High-Performance Design**: Optimized for large tables (100,000+ rows) using:\n  - Bulk insert operations with `SqlBulkCopy`\n  - Set-based updates via temporary tables\n  - Schema information caching\n- **Intelligent Comparison**: Only updates records that have actually changed\n- **Zero Configuration**: Automatically detects primary keys and table schemas\n- **Detailed Reports**: Comprehensive statistics for sync operations\n- **Error Handling**: Robust error handling with detailed feedback\n- **Async First**: Built with modern async patterns\n\n## 📦 Installation\n\nInstall via NuGet Package Manager:\n\n```\nInstall-Package BaseSync\n```\n\nOr via .NET CLI:\n\n```\ndotnet add package BaseSync\n```\n\n## 🚀 Quick Start\n\n\n```cs\nusing BaseSync;\n\n// Define connection strings\nstring localDb = \"Server=localhost;Database=LocalDB;Trusted_Connection=True;TrustServerCertificate=True;\";\nstring remoteDb = \"Server=remote-server;Database=RemoteDB;User Id=user;Password=password;TrustServerCertificate=True;\";\n\n// Specify tables to synchronize\nvar tables = new List\u003cstring\u003e { \"Customers\", \"Orders\", \"Products\" };\n\n// Perform synchronization\nSyncResult result = await BaseSync.SyncDataAsync(localDb, remoteDb, tables);\n\n// Check results\nforeach (var tableResult in result.TableResults) {\n\tConsole.WriteLine($\"Table: {tableResult.Key}\");\n\tif (tableResult.Value.IsSuccess) {\n\t\tConsole.WriteLine($\"  Pull: {tableResult.Value.PullInserts} inserts, {tableResult.Value.PullUpdates} updates\");\n\t\tConsole.WriteLine($\"  Push: {tableResult.Value.PushInserts} inserts, {tableResult.Value.PushUpdates} updates\");\n\t} else {\n\t\tConsole.WriteLine($\"  Error: {tableResult.Value.ErrorMessage}\");\n\t}\n}\n```\n\n\n## 🔄 How It Works\n\nBaseSync uses a sophisticated process to efficiently synchronize data:\n\n1. **Schema Discovery**: Automatically detects primary keys and columns for each table\n2. **Schema Caching**: Caches schema information to minimize database roundtrips\n3. **Data Retrieval**: Loads data from both source and destination databases\n4. **Memory-Efficient Comparison**: Creates dictionaries of destination rows indexed by primary key for O(1) lookups\n5. **Change Detection**: Identifies which rows need to be inserted or updated\n6. **Bulk Operations**:\n   - Uses `SqlBulkCopy` for fast insertion of new rows\n   - Creates temporary tables and performs set-based updates for changed rows\n7. **Bidirectional Sync**: First pulls from remote to local, then pushes from local to remote\n\n## 📊 Performance Optimizations\n\nBaseSync is engineered to handle large datasets efficiently:\n\n- **Reduced Database Roundtrips**: Performs bulk operations instead of row-by-row processing\n- **Memory Management**: Efficiently manages large datasets in memory\n- **Set-Based Operations**: Uses SQL's native strengths for updates via temp tables\n- **Caching**: Minimizes redundant schema queries\n\n## 🛠️ Requirements\n\n- .NET 9.0 or higher\n- SQL Server databases (source and destination)\n- Tables must have primary keys defined\n\n## 🤝 Contributing\n\nContributions are welcome!
