Modern enterprises face a critical operational challenge: maintaining real-time data consistency across specialized systems while avoiding the complexity and costs of traditional CDC implementations. Postgres CDC provides a method to share change events from Postgres tables without affecting database performance, leveraging logical decoding to extract information from the Write-Ahead Log (WAL) [1][2].

However, most CDC solutions force organizations into an impossible choice between operational speed, implementation complexity, and budget constraints. Traditional platforms like Debezium demand Kafka expertise, hosted solutions impose enterprise-level costs, and ETL providers introduce unacceptable latency for operational systems.

Stacksync eliminates these trade-offs through purpose-built bi-directional synchronization that delivers sub-second data consistency across CRMs, ERPs, and databases without the infrastructure overhead of traditional CDC platforms.

The Operational CDC Problem

Change data capture extracts record-level change events (INSERTs, UPDATEs, and DELETEs) from PostgreSQL in real-time, enabling fully event-driven data architectures that keep downstream systems always in sync [3]. Yet traditional CDC solutions fail operational requirements in three critical areas:

Latency and Reliability Issues

Most CDC platforms prioritize analytics over operations, introducing batch processing delays and one-way data flows that break real-time operational workflows.

Infrastructure Complexity

Traditional solutions require specialized streaming expertise, complex Kafka deployments, and dedicated engineering resources for maintenance.

Cost Inefficiency

Enterprise CDC platforms impose high licensing costs while demanding additional infrastructure investments, making them prohibitively expensive for mid-market organizations.

Stacksync: Purpose-Built Operational Synchronization

Stacksync addresses operational CDC challenges through a fundamentally different approach: true bi-directional synchronization with enterprise-grade reliability and zero infrastructure complexity.

Technical Superiority

Changes: Real-time logical replication with field-level change detection and instant bi-directional propagation

Guarantees: Exactly-once processing with native conflict resolution and automated error handling

Destinations: 200+ pre-built connectors spanning CRMs (Salesforce, HubSpot), ERPs (NetSuite, SAP), databases (PostgreSQL, MySQL, Snowflake), and streaming platforms

Operational Excellence

Unlike traditional CDC tools, Stacksync operates through your existing database infrastructure—no Kafka clusters, no streaming platform expertise, no infrastructure maintenance. Changes propagate with sub-second latency while maintaining absolute data consistency across all connected systems.

Enterprise-Ready Security

SOC 2 Type II, GDPR, HIPAA BAA, ISO 27001, and CCPA compliance ensure enterprise security standards without additional configuration overhead.

Proven ROI

Customer implementations demonstrate measurable operational improvements:

• Acertus: $30,000+ annual savings replacing Heroku Connect while improving real-time data availability
• Complete7: 50% faster IoT data updates with 40% less manual intervention
• Nautilus Solar: Seamless multi-system integration with automated workflow capabilities

Traditional CDC Platform Analysis

Free, Open Source Solutions

Debezium

Technical Assessment:

• Changes: Logical replication with inserts, updates, and deletes streaming to Apache Kafka [4]
• Guarantees: Exactly-once processing through Kafka's distributed architecture
• Destinations: Kafka topics only, requiring additional Connect framework

Implementation Complexity: Very High. Demands expertise in JVM, ZooKeeper, and Kafka management. Requires understanding esoteric PostgreSQL concepts like replication slots and logical decoding [1].

Budget Impact: High total cost of ownership despite free licensing, with significant engineering overhead for deployment and maintenance.

Assessment: Powerful but notoriously complex, requiring specialized Kafka expertise that diverts engineering resources from core business development.

Hosted Commercial Platforms

Confluent

Technical Assessment:

• Enterprise Debezium with managed infrastructure
• Exactly-once processing with enhanced monitoring
• Kafka ecosystem with extensive Connect framework

Implementation Complexity: Medium. Eliminates infrastructure management but requires deep Kafka configuration knowledge.

Budget Impact: Very high enterprise licensing with per-connector pricing plus Kafka infrastructure costs.

Assessment: Expensive enterprise solution that still demands Kafka expertise for configuration and maintenance.

Striim

Technical Assessment:

• Real-time change capture with enterprise transformations
• Exactly-once processing with comprehensive security features
• Multiple enterprise destinations with built-in connectivity

Implementation Complexity: Medium. Proprietary TQL language and StreamApps framework require platform-specific learning.

Budget Impact: Very high. All-in enterprise contracts designed for Fortune 1,000 companies.

Assessment: Enterprise-grade reliability but prohibitive costs and vendor-specific expertise requirements.

Cloud Provider Tools

AWS DMS, GCP Datastream, Azure Data Factory

Technical Assessment:

• Cloud-native logical replication with provider integration
• Variable guarantees depending on configuration
• Limited to respective provider ecosystems

Implementation Complexity: Medium. Requires navigating complex provider-specific interfaces and service configurations.

Budget Impact: Medium to high with unpredictable costs from compute, data transfer, and service dependencies.

Assessment: Viable for single-provider environments but creates vendor lock-in with complex pricing models.

ETL Platform Limitations

Fivetran, Airbyte, Stitch

These platforms excel at analytics workflows but fail operational requirements:

Operational Inadequacy: Mature solutions for one-way data replication to data warehouses for analytics and BI , but batch processing delays and unidirectional data flow prevent real-time operational synchronization.

Latency Issues: Processing delays from minutes to hours make them unsuitable for mission-critical operational systems requiring immediate data consistency.

Assessment: Analytics-focused tools that cannot meet operational CDC demands for real-time bi-directional data consistency.
