Blog Category: MySQL-aware Proxies

How the Continuent Proxy selects database cluster nodes for executing read operations.

In this short blog post, we examine the impact that setting the Tungsten cluster policy to Maintenance has on the cluster behavior, and specifically the impact on the Tungsten Connector.

This blog provides basic information about business-critical application to database connections; my team focuses on MySQL, MariaDB, and Percona Server for MySQL on Linux/Unix that’s infrastructure-agnostic (on-prem, VM, hybrid-cloud, cloud, multi-cloud, etc.).

Learn how and where the Connector communicates, and about the different SSL configurations possible.

View this presentation to learn about two types of (MySQL) database proxies, which we refer to as ‘fast & simple proxy’ and ‘intelligent proxy’; and how transparent failover and read-write splitting works for these.

Version 6+ of Tungsten Clustering comes with a host of improvements for your Multi-Site Multi-Master topology (MSMM); this is partly why it has a new name: Composite Master-Master (CMM). Probably the most notable improvement is that the Managers are more aware. What does that mean?

The Tungsten Connector is an intelligent MySQL proxy that provides key high-availability and read-scaling features. This includes the ability to route MySQL queries by inspecting them in-flight.

Make It Smarter: Tuning MySQL Client Request Routing for Tungsten Connector

Watch our new on-demand webinar: “An introduction to database proxies (for MySQL)”. From a simple database connectivity scenario all the way through to advanced database connectivity setups and proxy functionalities, this webinar provides a solid introduction to database proxies (for MySQL).

This is the first in a series of blogs we’ll be publishing in 2020 with regards to database proxies for MySQL, including our very own Tungsten Proxy, which we’ll introduce to the MySQL community in more detail in the coming months.

The power of Tungsten Clustering for MySQL / MariaDB is its built-in intelligent MySQL proxy, known as the Tungsten Connector. The Connector has built-in read-write splitting capabilities, and it is also possible to configure different algorithms which select the appropriate slave (i.e. Round-Robin or Lowest-Latency).

Database Proxies provide a single entry point into MySQL for the calling client applications. Proxies are wonderful tools to handle various situations like a master role switch to another node for maintenance, or for transparency with read and write connections. However, when the time comes to perform the switch action, all of the calling clients have been funneled through the proxy, so identification of the calling host from the database itself becomes difficult.
