new to pstop – vmstat style stdout interface
+0 Vote Up -0Vote Down

In November last year I announced a program I wrote called pstop. I hope that some of you have tried it and found it useful. Certainly I know that colleagues and friends use it and it has proved helpful when trying to look inside MySQL to see what it is doing.

A recent suggestion provoked me to provide a slightly different interface to pstop, that is rather than show the output in a terminal-like top format, provide …

Getting started Galera with Docker, part 1
+0 Vote Up -0Vote Down

by Erkan Yanar

 

Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.

 

This is the first of a series of blog posts about using Galera with …

MongoDB’s flexible schema: How to fix write amplification
+0 Vote Up -1Vote Down

Being schemaless is one of the key features of MongoDB. On the bright side this allows developers to easily modify the schema of their collections without waiting for the database to be ready to accept a new schema. However schemaless is not free and one of the drawbacks is write amplification. Let’s focus on that topic.

Write amplification?

The link between schema and write amplification is not obvious at first sight. So let’s first look at a table in the relational world:

mysql> SELECT * FROM user LIMIT 2; …

How to setup MySQL incremental backup
+2 Vote Up -0Vote Down

Incremental backups in MySQL were always a tricky exercise. Logical backup tools like mysqldump or mydumper don’t support incremental backups, although it’s possible to emulate them with binary logs. And with snapshot-based backup tools it’s close to impossible to take incremental copies.

Percona’s XtraBackup does support incremental backups, but you have to understand well how it works under the hood and be familiar with command line options. That’s not so easy and it’s getting worse when …

Information on the SSL connection vulnerability of MySQL and MariaDB
+0 Vote Up -0Vote Down

Last  week, a SSL connection security vulnerability was reported for MySQL and MariaDB. The vulnerability states that since MariaDB and MySQL do not enforce SSL when SSL support is enabled, it’s possible to launch Man In The Middle attacks (MITM). MITM attacks can capture the secure connection and turn it into an insecure one, revealing data going back and forth to the server.

Issue resolution in MariaDB is visible through the corresponding ticket in MariaDB’s tracking system (JIRA): https://mariadb.atlassian.net/browse/MDEV-7937
