G-Tech Moment | Worry-Free Active-Active, Simplified O&M: An In-Depth Look at GBase Visual Sync Tool GVR

Published on 2026-01-29

In the era of data-driven business, database high availability and disaster recovery capabilities are critical. To help users build an active-active cluster system for GBase 8a MPP Cluster more conveniently and efficiently, GBase has developed a powerful visual sync tool—GBase Visio Rsynctool (GVR for short).

GVR is a visual cluster active-active sync tool designed specifically for GBase 8a MPP Cluster. It features high flexibility, high performance, high availability, and ease of use, aiming to help users rapidly set up active-active clusters and achieve efficient, reliable data synchronization.

With GVR, users can say goodbye to complex script configurations and easily manage data sync tasks through an intuitive interface, meeting the needs of various business scenarios such as intra-city or remote disaster recovery and read-write separation.

What Core Pain Points Does GVR Address?

  • Rapidly Build Active-Active Clusters

No need to write complex scheduling scripts. You can easily create custom sync tasks and sync cycles through the GVR interface, flexibly configuring them based on actual business needs, significantly improving deployment efficiency.

  • Efficient Data Sync

It adopts an underlying binary data file sync mechanism, combined with optimizations such as pre-sync and metadata snapshots, to deliver high-performance transfer. During synchronization, the source table remains readable and writable, supporting PB-scale data sync with a single-node sync speed of up to 500 MB/s.

  • Flexible Task Configuration

Users can customize sync parameters according to business scenarios, such as whether to sync metadata, whether to overwrite sync, whether to limit speed, etc., meeting personalized needs in different scenarios.

What Scenarios Is GVR Suitable For?

GVR is suitable for two typical scenarios:

  • Intra-city/Remote Disaster Recovery Backup System

Suitable for large enterprises spanning regions, supporting two-site three-center high-availability deployment, and meeting the requirements of secure big data analytics systems with high RPO/RTO.

  • Read-Write Separation Active-Active Cluster

Suitable for business scenarios with high concurrency of DML and DQL. Write operations (DML) can be performed on Cluster A, and read operations (DQL) on Cluster B, with GVR syncing write operation data to the read cluster within a time window, achieving business separation and load balancing.

What Core Functions Does GVR Have?

As an important tool in the GBase 8a MPP Cluster ecosystem, GVR, through its visual, configurable, and high-performance sync mechanism, significantly lowers the barrier to building and operating active-active clusters. Whether for disaster recovery or read-write separation, GVR provides stable, flexible, and efficient data sync support, helping enterprises build a more reliable and agile data architecture.
