Seamless Data Synchronisation at Scale

Exploring how Fivetran HVR streamlines high-volume data replication, ensuring real-time accuracy, scalability, and resilience

In a data-driven world, synchronising information across complex systems is a core business need. As data volumes increase and applications diversify, maintaining accuracy and consistency across environments becomes increasingly challenging. Enterprises require real-time, reliable replication to support analytics, operations, and decision-making. 

The Challenge of Large-Scale Replication 

High-volume systems face daily issues with latency, inconsistency, and downtime, disrupting analytics and migration initiatives. Many legacy replication tools cannot keep pace with modern throughput demands or the complexity of hybrid architectures, resulting in performance bottlenecks and elevated costs. 

Why Fivetran HVR?

Fivetran’s High Volume Replicator (HVR) offers real-time data replication and synchronisation across diverse environments, including databases, files, cloud platforms, and legacy on-premises systems. Its Change Data Capture (CDC) engine reads directly from transaction logs, capturing only new or updated records. This log-based approach significantly reduces system load and latency while preserving source integrity, making it ideal for mission-critical and high-frequency data pipelines.

 

Key Benefits 
Automation and Resilience 

Fully automated pipelines adapt to schema changes and operational disruptions, reducing manual intervention and ensuring consistent uptime. 

Scalability 

HVR’s distributed hub-agent architecture allows horizontal scaling. Organisations can add hubs and agents as data demands grow, supporting large-scale deployments with minimal reconfiguration. 

Broad Compatibility

Supports integration across major databases and platforms, including SQL Server, Oracle, PostgreSQL, SAP HANA, and leading ERP and cloud applications. 

Minimal System Impact 

Only incremental changes are moved, maintaining performance on source systems even during large-scale replication. 

Security and Compliance 

Built-in encryption, auditing, and compliance with SOC 2, GDPR, and HIPAA make HVR suitable for enterprise and regulated environments. 

Architecture Overview 

Fivetran HVR is built around three key components: 

  • Hub: The central control point for managing connectivity, orchestration, and data movement. Deployable on-premises or in the cloud. 

  • Agents: Installed close to data sources to compress, encrypt, and transmit information securely while minimising network load. 

  • Channels: Define and control replication flows, supporting one-to-one, one-to-many, or many-to-one configurations. 

This modular structure enables near real-time replication across diverse data ecosystems without disrupting production performance.
