Percona Live ONLINE Talk: Enhancing MySQL security at LinkedIn by Karthik Appigatla

MySQL, arguably the most popular relational database, is used pretty extensively at the popular professional social network LinkedIn. At Percona Live ONLINE 2020, the company’s flagship event held online for the first time due to the Covid-19 pandemic, Karthik Appigatla from LinkedIN’s database SRE team discussed the company’s approach to securing their database deployment without introducing operational hiccups or adversely affecting performance.

Instead of just performing admin duties, Karthik’s team builds automated tools to scale their infrastructure, and he talked about some of these tailored tools in his presentation. The database SREs on his team also work with the developers at LinkedIn and help them streamline their applications to make best use of the database.

Talking about LinkedIn’s reliance on MySQL, Karthik said that not only do all their infrastructural tools rely on MySQL, many of the internal …

Disk of Yesteryear Compared to Today’s SSD Drives

In my last blog post I showed you how to get the entire Percona “Stack” up and running on a Raspberry Pi. This time around, I would like to show the impact on performance between using an SSD hard disk and a standard hard disk.

Disk performance is a key factor in Percona Server for MySQL (or any RDB platform) performance on a Raspberry Pi 4.

Test set up

Each test below was run three times per Hard Disk and I took the best of the three for comparison.

Hardware

  • Raspberry Pi 4+ with 4GB ram.
  • Disk 1: USB3 Western Digital My Passport Ultra, 1TB
  • Disk 2: USB3 KEXIN 240GB Portable External SSD Drive

Hardware stayed consistent …

Impact of innodb_file_per_table Option On Crash Recovery Time

Starting at version MySQL5.6+ by default innodb_file_per_table is enabled and all data is stored in separate tablespaces.

It provides some advantages. I will highlight some of them:

  • You can reclaim disk space when truncating or dropping a table stored in a file-per-table tablespace. Truncating or dropping tables stored in the shared system tablespace creates free space internally in the system tablespace data files (ibdata files) which can only be used for new InnoDB data.
  • You can store specific tables on separate storage devices, for I/O optimization, space management, or backup purposes. …

Blog from the Top — The Changing Landscape of Open Source (MySQL) and Money

This is the first in a series of blog articles in which I will discuss the changing landscape of open source and money. Or, more specifically, open source databases and money. And even more specifically MySQL and its all variants (AWS Aurora, MariaDB, Percona Server, RDS/MySQL) and money. But before going too deep into what is changing, let’s review all the traditional business models in and around the MySQL marketplace.

In general, these are the following types of companies in the MySQL commercial ecosystem, sorted by total annual revenue and addressable market size:

  • Developers who do not aim to monetize the open source code, just provide value to others and hope to get development and other contributions in return. This is the purest form of open source. For example, all …

Percona Live Presents: Globalizing Player Accounts with MySQL at Riot Games

During my presentation at Percona Live 2019, I’ll be talking about how Riot Games, the company behind League of Legends, migrated hundreds of millions of player accounts to unlock opportunities for us to delight players. This meant moving ten geographically distributed databases into a single global database replicated into four AWS regions. I’ll talk about some of the technical decisions we made, the expected vs actual outcomes, and lessons we learned along the way.

Migrating hundreds of millions of player records without impacting a player’s ability to manage their account and log in was a daunting task. I’ll shed some light on how we managed to handle this data migration while modifying the database schema. I’ll also go into detail on the backend …

Percona Live Presents: The First Ever TiDB Track

The PingCAP team has always been a strong supporter of Percona and the wider open source database community. As the people who work day in and day out on TiDB, an open source NewSQL database with MySQL compatibility, open source database is what gets us in the morning, and there’s no better place to share that passion than Percona Live.

At this year’s Percona Live Open Source Database Conference in Austin, Texas, we are particularly excited to bring you a full track of talks and demo on the latest development in TiDB during Day 1 of the conference.

Who would benefit from the TiDB track

The TiDB track is designed to share with developers, DBAs, and practitioners in general technical know-hows, reproducible benchmarks (no benchmark-eting), and best practices on how TiDB can solve their problems. …

A Truly Open Source Database Conference

Many of our regular attendees already know that the Percona Live Open Source Database Conference is not all about Percona software or, indeed, all about Percona. However, with moving to a new city—Austin, TX— we have realized that it’s something we ought to shout out loud and clear. Our conference really is technology agnostic! As long as submissions were related to open source databases then they were candidate for selection.

We have thirteen tracks at this year’s conference including a track entitled “Other Open Source Databases” which we are presenting alongside tracks dedicated to MySQL®, …
