Data Loading & Unloading

Tacnode provides comprehensive data loading/unloading capabilities to help you efficiently manage data flow in your applications. This section covers all aspects of data loading, unloading, and real-time change capture.

Overview

Data Loading & Unloading operations in Tacnode include:

• Data Import & Export: Bulk data operations using COPY, INSERT, and streaming protocols
• Change Data Capture (CDC): Real-time data change tracking and replication

Quick Navigation

Data Import and Export

Learn how to efficiently import and export data using various methods:

• COPY FROM/TO: Optimized for large datasets
• INSERT statements: Flexible insertion with conflict handling
• Performance optimization: Best practices for high-volume operations
• JDBC integration: Programmatic data operations

Change Data Capture (CDC)

Implement real-time data synchronization:

• Publications and Replication Slots: Core CDC concepts
• Configuration: Setting up logical replication
• Integration: Working with Apache Flink and other tools
• Monitoring: Tracking replication status and performance

Key Features

High Performance

• Optimized bulk operations with minimal overhead
• Batch processing for improved throughput
• Configurable conflict resolution strategies

Real-time Capabilities

• Logical replication for change capture
• At-least-once delivery guarantees
• Support for multiple output formats

Enterprise Integration

• PostgreSQL protocol compatibility
• JDBC driver support
• Integration with popular data processing frameworks

Getting Started

1. For bulk data operations: Start with Data Import and Export
2. For real-time data sync: Begin with Change Data Capture

Choose the appropriate method based on your use case:

• Use COPY for initial data loads and large batch operations
• Use INSERT for incremental updates and smaller datasets
• Use CDC for real-time data synchronization and streaming analytics
