Learn what triggers Tungsten Cluster failsafe-shun and how it helps maintain high availability in MySQL database clusters. Discover key factors and best practices for managing automatic node shunning.

In this blog we take a look at how you can use Tungsten Replicator to replicate data from multiple sources, and merge into a single target using 3 simple yet effective filters.

Replication is one of the most critical components of database management, especially in an Active-Active multi-primary composite cluster. However, with great flexibility comes the occasional hiccup. If you’re grappling with intermittent replication failures for a table in your Tungsten Cluster setup, here are five practical approaches to diagnose and resolve the issue.

Discover the benefits of Tungsten Active-Active Clustering for MySQL. Learn how this solution ensures high availability, scalability, low-latency data access, and disaster recovery for businesses with global operations.

Securing your cloud environment is now more critical than ever. As organizations increasingly rely on cloud platforms like Amazon Web Services (AWS), the potential for security breaches and unauthorized access becomes a pressing concern. AWS CloudTrail is a powerful tool that can help you monitor and detect suspicious activities in your AWS account. This blog post will guide you through the process of leveraging AWS CloudTrail to detect account intruders and strengthen your overall security posture.

Tungsten Clustering ensures high availability with robust failover capabilities, driven by the Tungsten Manager's health checks and predefined rules. In this blog post, we explore key processes like handling heartbeat gaps, network partitions, and availability checks. We also provide tips for tuning parameters to optimize performance and maintain a resilient database cluster.

This article explores some of the leading MySQL — also including MySQL variants MariaDB and Percona Server — high availability (HA) and disaster recovery (DR) solutions – in alphabetical order, including AWS Aurora, Continuent Tungsten, DIY MySQL clusters, Galera Cluster, and MySQL InnoDB Cluster.

Cloud-based managed MySQL services like Amazon Aurora promised simplicity, scalability, and cost savings. But as adoption grows, many organizations are uncovering hidden costs, operational challenges, and limitations. This blog explores why companies are migrating back to on-premises MySQL and how solutions like Tungsten Clusters are empowering them to regain control, cut costs, and ensure flexibility for their database infrastructure.

In the current MySQL ecosystem, organizations must focus on high availability and fault tolerance to ensure business continuity and maintain customer trust. A recent inquiry to prominent tech executives identified five key themes for achieving this: multi-region deployment to prevent single points of failure, automated self-healing for quick issue resolution, redundancy through system duplication, microservices architecture for improved resilience, and load balancing for efficient resource management. Continuent's Tungsten Clustering solution aligns with these strategies, making it an optimal choice for organizations managing critical workloads.

Standards allow modern systems to advance, and the REST specification is one very important example. Since this post is about the Tungsten API in specific, let me simply say this - a RESTful API adheres to six principles: Client-server, stateless, cacheable, uniform interface, layered system and optionally code on demand. As part of the watchability/monitoring goal, our software as of version 7.0.0 includes a proper RESTful API - what we call APIv2. This API is fully documented and public.

Tungsten Clustering allows for many types of maintenance to happen with no downtime at all. This blog post will explore how to upgrade the actual MySQL Server on all cluster nodes with zero downtime. These same steps may be used to upgrade the MySQL server or patch the OS.
