Hi Vitor,

Thanks. Yes, the source code for the report was written for Python 2.7 that was used in MySQL Shell 8.0.17 and earlier. But MySQL Shell upgraded Python to version 3.6, so some changes in the report are required. I have updated the blog to work with MySQL Shell 8.0.18 and later.

Best regards,
Jesper

Today, we will cover a totally different MySQL Shell plugin: InnoDB.

Currently only 3 methods have been created:

Those related to the Table space fragmentation, have already been covered in this recent article.

Let’s discover the getAlterProgress()method. This method allows us to have an overview of the progress of some alter statements status like:

• stage/innodb/alter table (end)
• stage/innodb/alter table (flush)
• stage/innodb/alter table (insert)
• stage/innodb/alter table (log apply index)
• stage/innodb/alter table (log apply table)
• stage/innodb/alter table (merge sort)
• stage/innodb/alter table (read PK and internal sort)
• stage/innodb/alter tablespace (encryption)

This is an output of the method:

Presentation of some of the new features of MySQL 8.0.18 released on October 14, 2019.

The post MySQL 8.0.18 New Features Summary first appeared on dasini.net - Diary of a MySQL expert.

Making backups over the network can be done in two ways: either save on disk and transfer or just transfer without saving. Both ways have their strong and weak points. The second way, particularly, is highly dependent on the upload speed, which would either reduce or increase the backup time. Other factors that influence it are chunk size and the number of upload threads.

Percona XtraBackup 2.4.14 has gained S3 streaming, which is the capability to upload backups directly to s3-compatible storage without saving locally first. This feature was developed because we wanted to improve the upload speeds of backups in Percona Operator for XtraDB Cluster.

There are many implementations of S3 Compatible Storage: …

Problem : 

We are running 5 node percona cluster on Ubuntu 16.04, and its configured with master-slave replication. Suddenly we got an alert for replica broken from slave server, which was earlier configured with normal replication 

We have tried to sync the data and configure the replication, unable to fix that immediately due to huge transactions and GTID enabled servers. So we have decided to follow with innobackupex tool, and problem fixed in 2 hours 
Followed all the steps from percona doc and shared the experience in my environment 
Steps involving to repair the broken Replication :
1.Backup master server  2.Prepare the backup  3.Restore and Configure the Replication 4Check Replication Status

What is great with MySQL Shell Plugins, it’s that it provides you an infinite amount of possibilities. While I was writing the part I and part II of the check plugin, I realized I could extend it event more.

The new methods I added to the plugin are especially useful when you are considering to use MySQL InnoDB Cluster in Multi-Primary mode, but not only

Let’s have a look at these new methods:

These 4 new methods are targeting large queries or large transactions. It’s also possible to get the eventual hot spots.

Let’s see the first two that are more basic in action:

The first method …

Introduction MySQL offers two types of clustering solution for managing Read/Write intensive workloads , ensuring Rock Solid Availability.

1.MySQL InnoDB Cluster
2. MySQL NDB Cluster

Glimpse of MySQL InnoDB Cluster    This Cluster is designed for users that uses MySQL Server with InnoDB storage engine.    It will serve as a natural extension for users currently using MySQL Replication with InnoDB to a       new replication architecture i.e Clustering on top of Group Replication. MySQL InnoDB Cluster = MySQL Server + MySQL Shell + MySQL Router.
MySQL Server

• Group Replication Technology.
• Single-Primary /Multi-Primary Mode.
• Fault Tolerance.
• Conflict detection and resolution.
• Automatic distributed recovery.
