Change Data Capture (CDC) Script

enterprise

Project Overview

The CDC Script is a Python-driven solution for implementing Change Data Capture across MySQL and PostgreSQL databases. Its purpose was to provide organizations with a unified way to track and audit row-level changes without needing vendor-specific tools. The script dynamically inspects database schemas and automatically generates triggers that record both pre- and post-update states of modified rows. This ensures a detailed historical record of all data changes, greatly enhancing compliance, traceability, and troubleshooting. By supporting multiple SQL engines with one adaptable script, the solution reduces overhead while providing a flexible auditing mechanism for diverse environments.

Technical Insights

  • Inspected information_schema tables dynamically to identify table/column structures.
  • Generated database-specific triggers, accounting for differences between MySQL and PostgreSQL.
  • Designed audit tables to store historical row states for traceability.
  • Created a single script adaptable to multiple database backends.
