Modern operational systems demand instant data consistency across applications, databases, and analytics platforms. While Debezium is an open-source distributed platform for change data capture built on top of Apache Kafka, capturing row-level changes from various databases [1], including PostgreSQL, the implementation complexity creates significant operational overhead for development teams.
Organizations implementing PostgreSQL Change Data Capture (CDC) face a fundamental challenge: the WAL is a transaction log that notes all changes in the database, primarily for recovery and ensuring data integrity, making it useful for event-based CDC [2]. However, traditional approaches require extensive configuration, infrastructure management, and specialized expertise to maintain.
This comprehensive guide examines the limitations of complex CDC implementations and demonstrates how Stacksync provides enterprise-grade real-time data synchronization with true bi-directional capabilities, eliminating the operational complexity that plagues traditional solutions.
The PostgreSQL CDC Challenge
Traditional CDC Implementation Complexity
PostgreSQL CDC implementation through tools like Debezium requires managing multiple interconnected components. Postgres CDC is driven by its Write-Ahead Logging, with CDC tools reading from this log to capture changes as they occur, providing real-time change streams without placing strain on the Postgres server [3].
However, the architectural complexity extends far beyond simple log reading:
Infrastructure Dependencies:
- Apache Kafka cluster configuration and management
- ZooKeeper for distributed coordination
- Kafka Connect framework setup and maintenance
- PostgreSQL logical replication configuration
- Complex networking and security configurations
Operational Overhead:
- Esoteric PostgreSQL details like replication slots and logical decoding [3] management
- Continuous monitoring of multiple system components
- Manual troubleshooting of sync failures and performance issues
- Schema evolution handling across distributed systems
- Resource allocation and scaling management
Performance and Reliability Limitations
Traditional CDC implementations suffer from inherent architectural limitations that impact enterprise operations:
Latency Issues:
- Fivetran having up to 30-minute latency [1] compared to real-time requirements
- Multi-stage processing through Kafka topics introduces delays
- Complex transformation pipelines add processing overhead
Reliability Challenges:
- Change Data Capture platforms deliver impressive results, but they're not bulletproof with challenges to watch out for [4]
- Multiple failure points across distributed components
- Complex error handling and recovery procedures
- Data consistency issues during system failures
Stacksync: Purpose-Built Real-Time Data Synchronization
Stacksync eliminates CDC complexity through a fundamentally different architectural approach designed for operational systems requiring guaranteed data consistency and sub-second synchronization latency.
