AWS may reboot your Aurora database. What is the impact?

In this blog, part of a series of “Recently a Customer Asked” posts for Tungsten University, we explore the reason for the occasional Tungsten Replicator OFFLINE:ERROR state when applying to AWS Redshift, along with possible steps to compensate for the issue.

When external issues cause the primary extractor to go offline, we address the issue and bring the extractor back online. However, we need to make sure we start the extraction from the correct position so that the downstream replicas receive transactional data they require. Let’s determine the position and how we set it.

Beyond uptime lies the calm harbor of long-term administration for your MySQL high-availability solution. But navigating upgrade waves and vendor lock-in can be tricky. Let's chart a smooth course through these challenges and ensure your data sails serenely.

Explore the benefits of migrating from Galera Cluster to Tungsten Cluster for MySQL database infrastructure. Learn how Tungsten leverages asynchronous replication for robust performance, overcoming challenges faced by synchronous replication. Discover the ideal architecture for Geo-Scale MySQL clustering and how Tungsten Cluster simplifies deployment with CLI and GUI management tools. Gain insights into achieving high availability, Active/Passive, or Active/Active clusters.

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.

This article will explain how to use rsync to quickly provision a database.

Learn why Aurora Global Database from Amazon may not be a truly global solution for multi-region deployment, and how Tungsten Cluster can help achieve seamless failover in the event of regional outages, without affecting unaffected regions, keeping applications online, and with failback capability.

VMware chose to migrate key MySQL database from Galera (MariaDB Cluster) to Tungsten. In this blog we will look at the key reasons for why VMware ultimately decided that Tungsten Cluster would better fit their multi-site MySQL clusters.

You already know that you need to back up your database, but it takes so long and requires a lot of compute resources. With a few tricks, we can make the backup process quick!

In this blog, we cover tprovision. tprovision is a complete rewrite of the provisioning tool “tungsten_provision_slave,” included with Tungsten Cluster. It is streamlined and allows easy provisioning of replica databases.

Deploying Composite Active/Active clusters gives end-users the best experience no matter where they are located. Tungsten Cluster makes this possible with the deployment of MySQL clusters at geo-scale, allowing the enterprise to host clusters close to the users. How can we avoid write-conflicts with asynchronous replication and multiple primary databases?
