Consequences of Forcing Bootstrap on Percona XtraDB Cluster

Recently, I was working on a very unfortunate case that revolved around diverging clusters, data loss, missing important log errors, and forcing commands on Percona XtraDB Cluster (PXC). Even though PXC tries its best to explain what happens in the error log, I can vouch that it can be missed or overlooked when you do not know what to expect.

This blog post is a warning tale, an invitation to try yourself and break stuff (not in production, right?).

TLDR:
Do you know right away what happened when seeing this log?

Exploring Data Dump and Load Utility With MySQL Shell

In this blog post, I will try to cover a few dump and data-loading utilities offered by MySQL Shell.

What is MySQL Shell?

It is a robust client and code editor for MySQL. In addition to having APIs for dealing with MySQL, MySQL Shell offers scripting capabilities for JavaScript and Python. It provides an AdminAPI to manage MySQL servers and create InnoDB Cluster and ReplicaSet deployments. It supports an X DevAPI to work on both SQL and NoSQL interfaces via the X Protocol. Finally, it provides utilities to make working with MySQL in Python and Javascript mode easier.

Now, let’s jump into some practical stuff and see what these tools offer us.

Dump Utility

In the dump utility, there are three tools: util.dumpInstance(), util.dumpSchemas(), and util.dumpTables () so let’s discuss them one by one. 

1.  “util.dumpInstance()” – This was introduced in MySQL Shell 8.0.21 and …
