Operationalizing TokuDB
+0 Vote Up -0Vote Down

In my previous post, I talked about implementing multi-threaded replication (MTR) using Percona Server 5.6. The server pairs that are utilizing MTR are also exclusively using the TokuDB storage engine.

I find TokuDB to be a fascinating engine. I can tell I will need to re-watch our Dbhangops session where Tim Callaghan talked about the differences …

Employee +1 Vote Up -0Vote Down

With MySQL Enterprise Backup(MEB) 3.9.0 we had introduced full instance backup feature for cloning the MySQL server.

As part of full instance backup, copying of binlog files is default behavior MEB-3.11.0 onwards. DBA should be aware of the fact that current full instance backup is …

How to shrink the ibdata file by transporting tables with Trite
+0 Vote Up -0Vote Down

You’ve probably had some troubles with the shared InnoDB tablespace stored in the ibdata file. Especially when it has grown for some reasons and reached a critical size.

This behavior occurs in some cases, due to excessive rollback segments growth or during a migration from a unique shared tablespace to a file-per-table configuration for example.

In this post, I would like to explain how to shrink the ibdata file after an unwanted file growth in a file-per-table configuration.
Note that the process could be done without Trite but the tool avoids to write the script used to transport tables yourself.

Selective Restore of InnoDB Tables with MySQL Enterprise Backup 3.11
Employee +1 Vote Up -0Vote Down

Introduction

For example, suppose that some data was accidentally deleted from one table due to a software error, then the easiest way to recover the lost data might be to restore only one table from a backup. Previously this kind of partial restore was not supported by MySQL Enterprise Backup (MEB). However, MEB 3.11 introduces support for selective restore from backups created with the …

Optimistic Backup
Employee +2 Vote Up -0Vote Down

Introduction 

MySQL Enterprise Backup (MEB) is a highly efficient tool for taking backups of your MySQL databases. In the 3.11.0 release we are taking that one step further by introducing a new concept called "optimistic" backup. Optimistic backup leverages the patterns we saw frequently especially as related to very large databases.

For backups the goals are:
1 - Quality and Consistency - the backup and more importantly the restore just "works"
2 - Size, time, and overhead - like in the game of golf - low score wins - for backups and for
     restores.
3 - Flexibility – It’s …
