MariaDB MaxScale Masking Basics and Examples

I wanted to take a moment to write up a post on MariaDB MaxScale’s masking basics and include some real-world examples.

We have nice documentation on the subject, and Dipti wrote a nice blog post on it as well. I just wanted to provide my take on it, and hopefully build upon what is already there and offer some additional insights.

To provide a 50-foot overview, the masking filter makes it possible to obfuscate the returned value of a particular column.

3 quite common columns where this would be very beneficial: Social Security Number (“SSN”), Date of Birth (“DOB”), and Credit Card Number (“CCNUM”).

To use masking, it assumes you already have a MaxScale service up and running. For instance, the readwrite …

Viewing the Originating Host or IP Address with MaxScale’s Proxy Protocol

If you use MaxScale to route queries from various servers to some MariaDB server(s), when viewing the processlist on the MariaDB server, you will see MaxScale’s host for any “host” information related to that connection or its queries.

When tracking down problematic queries, it can be helpful to know what originating host of that query.

MaxScale’s proxy protocol to the rescue.

The proxy protocol was introduced in MaxScale 2.2 and MariaDB 10.3.

To enable it, it is quite simple (essentially just 2 changes).

1. In MariaDB, you need to set the variable proxy_protocol_networks in your my.cnf file (you can specify comma-separated IP addresses and/or subnetworks, as well as localhost and ::1):

proxy-protocol-networks=::1,, localhost

This one, which I will use as-is, is the example from the …

Making Maxscale/ProxySQL Highly Available ( 2 > 1 )

As Mydbops we are implementing Load Balancer using Maxscale or ProxySQL ( Our presentation ) for lot our client,  but these load balancers will become a SPOF (Single Point of failure) .  We have tried to explore services like HAProxy, Nginx, and Keepalived etc. Except Keepalived, all the services need to run on the standalone instance and  did not satisfy our exact need.

Keepalived does not requires any standalone instance, it can be deployed and configured with a minimal effort and provide the HA Solutions to the DB Infra. This approach not only fits for our DB setup, we can implement same …

The State of MySQL High Availability Going in to 2018

High availability for MySQL has become increasingly relevant given the ever increasing rate of adoption and implementation. It’s no secret to anyone in the community that the popularity of MySQL has become noteworthy. I still remember my start with MySQL in the early 5.0 days and people told me that I may not want to consider wasting my time training on a database that didn’t have a large industry adoption, but look at where we are now! One of my favorite pages to cite when trying to exhibit this fact is the ranking trend page where we can see that MySQL is right up there and contending with enterprise products such as Microsoft SQL Server and Oracle.

MySQL has gone from being part of the ever famous LAMP stack for users looking to set up their first website to seeing adoption from major technical players such as …
