dasini.net – Diary of a MySQL expert

As the administrator of a cluster, among other tasks, you should be able to restore failed nodes and grow (or shrink) your cluster by adding (or removing) new nodes.
In MySQL, as a backup tool (and if your amount of data is not too big), you can use mysqldump a client utility that performs logical backups.
The results are SQL statements that reproduce the original schema objects and data.
For substantial amounts of data however, a physical backup solution such as MySQL Enterprise Backup is faster, particularly for the restore operation.
But this is the topic of my next blog post 🙂

MySQL 8.0 provides another way to handle JSON documents, actually in a “Not only SQL” (NoSQL) approach…

Did you know that?

MySQL Enterprise Data Masking and De-Identification hides sensitive information by replacing real values with substitutes in order to protect sensitive data while they are still look real and consistent.

In this seventh episode of the MySQL Security series, we will see how MySQL Enterprise Firewall can help you to strengthen the protection of your data, in real-time, against cyber security threats like SQL Injection attacks by monitoring, alerting, and blocking unauthorized database activity without any changes to your applications.

In this sixth episode of the MySQL Security series, we will see how data-at-rest encryption helps organizations implement stronger security controls and satisfy regulatory compliance.
You will be able to protect the privacy of your information, prevent data breaches and help meet popular regulatory requirements including GDPR, PCI DSS, HIPAA with MySQL Enterprise Transparent Data Encryption aka TDE.

In order to spot database misuse and/or to prove compliance to popular regulations including GDPR, PCI DSS, HIPAA, … database administrators can be required to record and audit database activities. In this fifth episode of the MySQL Security series, we will see what MySQL Enterprise Audit provide to help organizations implement stronger security controls and satisfy regulatory compliance.

There are 3 pillars for a database architecture: Monitoring, Backup / Restore process, High Availability
This blog post is about database High Availability; more precisely about one of the best combo of the moment :
MySQL 5.7 Group Replication : the only native HA solution for MySQL, it’s a Single/Multi-master update everywhere replication plugin for MySQL with built-in automatic distributed recovery, conflict detection and group membership.
ProxySQL 1.4 : probably the best proxy for MySQL.
