For the third year in a row, we will take advantage of the mass presence of our MySQL Engineers during FOSDEM to organize the pre-FOSDEM MySQL Day.

The program of this 3rd edition is already on track, thank you to all the speakers who already confirmed their participation.

MySQL Shell is a command-line shell for MySQL Server that has the capability for
interactive and batch code execution.  It also offers a wealth of APIs that make it easier and more efficient to work with and manage MySQL servers. In 8.0.13, we made an effort to make those APIs easily accessible straight from the command line.…

The latest release of the MySQL Shell 8.0.13 (GA) introduced some interesting improvements and features, for more information see the full changelog here: https://dev.mysql.com/doc/relnotes/mysql-shell/8.0/en/mysql-shell-news-8-0-13.html. One of those features was the introduction of a convenient and easy way to import JSON documents to a MySQL Server database.…

Recently we had a customer that had issues with a filled disk on the server hosting their Docker pmm-server environment. They were not able to access the web UI, or even stop the pmm-server container because they had filled the /var/ mount point.

Setting correct expectations

The best way to avoid these kinds of issues in the first place is to plan ahead, and to know exactly with what you are dealing with in terms of disk space requirements. Michael Coburn has written a great blogpost on this matter:

We are now using …

The MySQL Development Team is very happy to announce the second 8.0 Maintenance Release of InnoDB Cluster!

In addition to bug fixes, 8.0.13 brings some new exciting features:

• Defining the next primary instance “in line”
• Defining the behavior of a server whenever it drops out of the cluster
• Improved command line integration for DevOps type usage

Here are the highlights of this release!…

My talk is titled Need for speed: Boosting Apache Cassandra’s performance using Netty. Over the years that I have worked in the software industry, making code run fast has fascinated me. So, naturally when I first started contributing to Apache Cassandra, I started looking opportunities to improve its performance. My talk takes us through some interesting challenges within a distributed system like Apache Cassandra and various techniques to significantly improve its performance. Talking about performance is incredibly exciting because you can easily quantify and see the results. Making improvements to the database’s performance not only improves the user experience but also reflects positively on the organization’s bottom line. It also has the added …

The MySQL Development team is proud to announce a new version of the MySQL Shell which in addition to the usual bug fixes and enhancements to the existing components,  offers new features we expect are quite useful in your day to day work.…

In the context of providing managed WordPress hosting services, at Presslabs we operate with lots of small to medium-sized databases, in a DB-per-service model, as we call it. The workloads are mostly reads, so we need to efficiently scale that. The MySQL® asynchronous replication model fits the bill very well, allowing us to scale horizontally from one server—with the obvious availability pitfalls—to tens of nodes. The next release of the stack is going to be open-sourced.

As we were already using Kubernetes, we were looking for an operator that could automate our DB deployments and auto-scaling. Those available were doing synchronous replication using MySQL group replication or Galera-based replication. Therefore, we decided to write our own operator.

Solution architecture

In our work, We used to get a lot of requirements for replicating data from one data source to another.Previously I wrote replication from MySQL to Red-shift.

In this blog I am going to explain about replicating the data from MySQL to Oracle using Tungsten replicator.

1.0. Tungsten Replicator :

It is an open source replication engine supports data extract from MySQL, MySQL Variants such as RDS, Percona Server, MariaDB and Oracle and allows the data extracted to be applied on other data sources such as Vertica, Cassandra, Redshift etc.

Tungsten Replicator includes support for parallel replication, and advanced topologies such as fan-in and multi-master, and can be used efficiently in cross-site deployments.

1.1.0. Architecture :

There are three major …

Our philosophy and approach to production secret management Keys are handed off during a check-in in Shanghai

Airbnb is a global community built on trust. The Security team helps to build trust by maintaining security standards to store, manage and access sensitive information assets. These include secrets, such as API keys and database credentials. Applications use secrets to provide everyday site features, and those secrets used to access production resources are particularly important to protect. This is why we built an internal system we call Bagpiper to securely manage all production secrets.

Bagpiper is a collection of tools and framework components Airbnb uses in all aspects of production secret management. This includes storage, rotation and access. More importantly, Bagpiper provides a safe, repeatable pattern that can be applied across Engineering. It is designed to be language and …
