​In this post, we are going to see how we can backup encrypted tables using Xtrabackup. InnoDB supports data encryption for InnoDB tables stored in file per table tablespaces. For the application to access encrypted tablespace, InnoDB will use master encryption key to decrypt the tablespace key. The master encryption key is stored in a keyring file in the location specified by the key_ring_file_data configuration option. We have already discussed on enabling encrypted tablespace. Here, we will try full and incremental backups of encrypted tablespace.

Percona xtrabackup supports encrypted innodb tablespace backups. While taking backup, we have to add –keyring-file-data and –server-id. After the completion of the backup, we have to use the same options to prepare the backup. Below is an example of encrypted table,

Backup can be taken without using –keyring-file-data and –server-id and the …

Notes/errata/updates for Chapter 5:
See the official book errata at http://tahaghoghi.com/LearningMySQL/errata.php – Chapter 5 is pages 135-177.

Notes:
If you did not load the sample databases in Chapter 3 as per page 102, you can download the file to import from http://tahaghoghi.com/LearningMySQL/Downloads/Files/Data/SQL_files_with_foreign_key_references/music.sql

On page 162, it says “In Chapter 6, we’ll discuss how to load data from existing tables or from external data sources.” but this content is in Chapter 8.

On page 169, it has an example of “DELETE FROM played;” which deletes all the rows of a table. This will not work if safe_updates are enabled. I always advise that if you …

One of the widely discussed technologies at Percona Live Europe was the logistics of running MySQL in containers. Containers – particularly Docker – have become a hot topic, so there was a good-sized crowd on day one of the conference for Ashraf Sharif, Senior Support Engineer with Severalnines. He presented his talk “MySQL on Docker: Containerizing the Dolphin”. 

During his presentation, Ashraf shared some recommendations for best practices when setting out on containerizing MySQL. He sees the trend of moving to containers as a progression from the use of virtual hosts.

After his talk on day one of the Percona Live Europe conference, I caught up with Ashraf and asked about his presentation. I was interested in which concepts are most important for …

MySQL Connector/Node.js is a new Node.js driver for use with the X
DevAPI. This release, v8.0.8, is the second development release of the

the strengths of the relational and document models using a modern,
NoSQL-like syntax that does not assume previous experience writing
traditional SQL.

MySQL Connector/Node.js can be downloaded through npm (see
https://www.npmjs.com/package/@mysql/xdevapi for details) or from
https://dev.mysql.com/downloads/connector/nodejs/.
