MySQL Cluster | Andrew Morgan on Databases

MySQL Cluster powers the subscriber databases of major communication services providers as well as next generation web, cloud, social and mobile applications. It is designed to deliver:

  • Real-time, in-memory performance for both OLTP and analytics workloads
  • Linear scale-out for both reads and writes
  • 99.999% High Availability
  • Transparent, cross-shard transactions and joins
  • Update-Anywhere Geographic replication
  • SQL or native NoSQL APIs
  • All that while still providing full ACID transactions.

Understand some of the highlights of MySQL Cluster 7.4:

  • 200 Million queries per minute
  • Active-Active geographic replication with conflict detection and resolution
  • 5x faster on-line maintenance activities
  • Enhanced reporting for memory and database operations

PMM Query Analytics

The QAN is a special dashboard which enables database administrators and application developers to analyze database queries over periods of time and find performance problems. QAN helps you optimize database performance by making sure that queries are executed as expected and within the shortest time possible. In case of problems, you can see which queries may be the cause and get detailed metrics for them.

nginx as Database Load Balancer for MySQL or MariaDB Galera Cluster | Severalnines

Recently, nginx 1.9 introduced support for TCP load balancing – similar to what HAProxy is capable of. The one major drawback is that it does not support advanced backend health checks. This is required when running MySQL Galera Cluster, as we’ll explain in the next section. Note that this limitation is removed in the paid-only edition called NGINX Plus.

Google Cloud Platform Blog: Scaling MySQL in the cloud with Vitess and Kubernetes

Vitess is available as an open-source project and runs best in a containerized environment. With Kubernetes and Google Container Engine as your container cluster manager, it’s now a lot easier to get started. We’ve created a single deployment configuration for Vitess that works on any platform that Kubernetes supports.

In addition to being easy to deploy in a container cluster, Vitess also takes full advantage of the benefits offered by a container cluster manager, in particular:

  • Horizontal scaling – add capacity by launching additional nodes rather than making one huge node
  • Dynamic placement – let the cluster manager schedule Vitess containers wherever it wants
  • Declarative specification – describe your desired end state, and let the cluster manager create it
  • Self-healing components – recover automatically from machine failures

In this environment, Vitess provides a MySQL storage layer with improved durability, scalability, and manageability.

Introducing Orchestrator: manage and visualize your MySQL replication topologies and get home for dinner | code.openark.org

I’m happy to announce the availability of Outbrain’s Orchestrator: MySQL replication management & visualization tool.

  • Orchestrator reads your replication topologies (give it one server – be it master or slave – in each topology, and it will reveal the rest).
  • It keeps a state of this topology.
  • It can continuously poll your servers to get an up to date topology map.
  • It visualizes the topology in a clear and slick D3 tree.
  • It allows you to modify your topology; move slaves around. You can use the command line variation, the JSON API, or you can use the web interface.
