Learn how to optimize MySQL replication performance in Tungsten Cluster by tuning the Applier settings. Improve replication speed, minimize commit overhead, and balance data availability with advanced tuning techniques.

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.

Tungsten Dashboard v1.0.16 is now available, featuring a crucial bug fix that resolves a regression in the configuration processing function. This update ensures smoother and more reliable performance, helping you maintain seamless workflows. Update today to benefit from the enhanced stability of your dashboard experience.

Your MySQL database cluster contains your most business-critical data; in this post, we discuss how to ensure proper performance under load.

In this blog post we explore various options for performance tuning MySQL server for better replica replication performance.

The Question

Recently, a customer asked us:

Why would heavy disk IO cause the Tungsten Manager and not MySQL to be starved of resources?

For example, we saw the following in the Manager log file tmsvc.log:

This blog post discusses the Tungsten Replicator and how latency is calculated when extracting events on a Primary, and when applying events to the Replicas. We also examine what latency is, and the two different types of latency that we track - how to interpret them and how they differ.

Explore the benefits of moving from Galera Cluster to Tungsten Cluster in our blog series. Learn how Tungsten's asynchronous replication enhances application performance compared to Galera's synchronous replication. Discover the advantages of network tolerance, performance optimization, and scalability. Follow our series for insights into deploying database clusters at geo-scale with Tungsten Cluster.

In this post, we will do a deep dive into how the Tungsten Replicator Parallel Applier works, and introduce a NEW filter for Parallel Apply called ShardByRulesFilter.

This blog discusses some of the ways you can configure your MySQL / MariaDB / Percona Server replicas using Tungsten Clustering.
