Test MySQL 8.0 right in your computer

MySQL 8.0 GA is right around the corner. I don't have precise information about its release, as I don't work at Oracle. If I did, I would probably know, but I couldn't tell when the release is scheduled to appear because of company policies. I can, however, speculate and infer, based of my experience with previous releases. My personal assessment is that the release will appear before 9:00am PT on April 24, 2018. The "before" can be anything from a few minutes to one week in advance.
Then, again, it may not happen at all if someone finds an atrocious bug that needs to be fixed asap.

Either way, users are keen on testing the new release in its current state of release candidate. Here I show a few methods that allow you to have a taste of the new …

Plot MySQL Data in Real Time Using Percona Monitoring and Management (PMM)

In this blog post, we’ll show that you can plot MySQL data in real time using Percona Monitoring and Management (PMM).

In my previous blog post, I showed how we could load into any metrics, benchmarks into MySQL and visualize it with PMM. But that’s not all! We can even visualize most any kind of data from MySQL in real time. I am falling in love with the MySQL plugin for Grafana — it just makes things so easy and smooth.

This graph shows us the number of visitors to a website in real …

Migrate to Amazon RDS Using Percona Xtrabackup

In this blog post, we’ll look at how to migrate to Amazon RDS using Percona XtraBackup.

Until recently, there was only one way to migrate your data from an existing MySQL instance into a new RDS MySQL instance: take and restore a logical backup with mysqldump or mydumper. This can be slow and error-prone. When Amazon introduced Amazon Aurora MySQL, you could use Percona XtraBackup to take an online physical backup of your database and restore that into a new Aurora instance. This feature is now available for RDS MySQL as well. Using Percona XtraBackup instead of a logical backup can save a lot of time, especially …

dbdeployer GA and semantic versioning

dbdeployer went into release candidate status a few weeks ago. Since then, I added no new features, but a lot of tests. The test suite now runs 3,000+ tests on MacOS and a bit more on Linux, for a grand total of 6,000+ tests that need to run at least twice: once with concurrency enabled and once without. I know that testing can't prove the absence of bugs, but I am satisfied with the results, since all this grinding has allowed me to find several bugs and fix them.

In this framework, I felt that dbdeployer could exit candidate status and get to version 1.0. This happened on March 26th. An immediate side effect of this change is that from this point on, dbdeployer must adhere to the semantic versioning principles:

A version number is made of Major, Minor, and Revision. When changes are applied, the following happens:

MySQL NDB Cluster Backups

Tweet

Today – 31 March – is world backup day, so I thought I would write a little about backups in MySQL NDB Cluster.

Just because NDB Cluster offers built-in redundancy and high availability does not mean backups are not important. They are – as ever and as for everything in software. The redundancy does not protect against user errors (anyone ever executed DROP TABLE or DROP SCHEMA by accident?) neither does it protect against a natural disaster, fire, or another disaster hitting the data center. Similar with high availability.

In short, if the data is in any way remotely important for you, you ensure you have a backup. Furthermore, a backup is not worth any more than your ability to restore it. If …

Multi-Source Replication Performance with GTID

In this blog post, we’ll look at the performance of multi-source replication with GTID.

Multi-Source Replication is a topology I’ve seen discussed recently, so I decided to look into how it performs with the different replication concepts. Multi-source replication use replication channels, which allow a slave to replicate from multiple masters. This is a great way to consolidate data that has been sharded for production or simplify the analytics process by using the same server. Since multiple masters are taking writes, care is needed to not overlook the slave. The traditional replication concept uses the binary log file name, and the position inside that file.

This was the standard until the release of global transaction identifiers (GTID). I have set up a test environment to validate which concept would perform better, and be a better choice for use in this topology.

SETUP

My test suite …

Analyze MySQL Audit Logs with ClickHouse and ClickTail

In this blog post, I’ll look at how you can analyze MySQL audit logs (Percona Server for MySQL) with ClickHouse and ClickTail.

Audit logs are available with a free plugin for Percona Server for MySQL (https://www.percona.com/doc/percona-server/LATEST/management/audit_log_plugin.html). Besides providing insights about activity on your server, you might need the logs for compliance purposes.

However, on an active server, the logs can get very large. Under a sysbench-tpcc workload, for …
