Performance Schema and Sys Schema in MySQL 5.7Mark Leith
MySQL 5.7 now includes the Sys Schema by default, which builds upon the awesome instrumentation framework laid by Performance Schema.
Performance Schema has had 23 worklogs completed in 5.7 alone, such as memory instrumentation, tying in transactions and stored programs in to the current statement/stage/wait instruments and wait graph, prepared statement instruments, metadata lock information, improved session status and variable reporting, the new structured replication tables, and more.
The Sys schema builds upon this strong foundation with easy reporting views and functions, as well as procedures to help both set up and manage the configuration of Performance Schema, and help diagnose performance issues with your database instances on the whole.
Come along and hear from the original developer of the Sys schema about all of these exciting improvements in MySQL instrumentation for the upcoming MySQL 5.7 release!

MySQL High Availability with Group ReplicationNuno Carvalho
MySQL Group Replication is a MySQL plugin that combines distributed systems technologies with database replication. The outcome of fusing such technologies is a resilient, multimaster update-everywhere replication solution for MySQL. At its core is a group communication service providing reliable and dependable message-passing for a group of MySQL servers. This enables automatic and consistent coordination between all the participants in a group. Such automatic orchestration of MySQL servers results in a fault-tolerant replicated state machine providing a highly available MySQL data store.

MySQL High Availability and Disaster Recovery with Continuent, a VMware companyContinuent
Users seeking high availability, disaster recovery and zero downtime maintenance operation for business-critical MySQL applications face confusing choices. Is multi-master or master/slave clustering better? What about synchronous versus asynchronous replication? Using a plain vanilla, stock MySQL or a modified version of it? Which of these choices are right for data-driven businesses that depend on fast, reliable data access?
This no-BS webinar cuts through the FUD to explore the real trade-offs between the different clustering and replication methods, thens show you how Continuent's asynchronous master/slave clusters support these important capabilities for business-critical applications:
- High application write rates Master/slave clustering with Continuent
- Mixed workloads consisting of large and small transactions
- Data across multiple geographically distributed locations
- Failures and more importantly recovery from them
- Zero downtime maintenance and software upgrades
- Use of off-the-shelf MySQL/MariaDB to avoid application changes and allow clusters to improve as MySQL itself does.
We illustrate key points with demonstrations and case studies from deployed systems.
Every website wants to become successful. Few websites however undertake the basic and fundamental steps to build a rock solid foundation to ensure a scalable
High Availability Using MySQL Group ReplicationOSSCube
MySQL Group Replication is a recent MySQL plugin that brings together group communication techniques and database replication, providing both a high availability and a multi-master update everywhere replication solution.
The PPT provide provide a broad overview of MySQL Group Replication plugin, what it can achieve and how it helps keep your MySQL databases highly available and your business up and running, without fail.
Java MySQL Connector & Connection Pool Features & OptimizationKenny Gryp
This talk will give an overview of the different available Java MySQL connectors (Connector/J, MariaDB Java Connector) and connection pools (Commons-DBCP, C3P0, ...).
One of the things with the default configuration of these solutions is that they are very chatty. This can have a noticeable impact on application performance and database load. I've seen many environments where over 50% of the total amount of queries are caused by such behavior. This behavior will be explained through examples seen on production systems as well as recommendations on optimization will be made.
Load balancing and transparent failover solutions will be described for both MySQL's traditional asynchronous replication and Galera based replication (Percona XtraDB Cluster or MariaDB Galera Cluster).
Percona XtraDB Cluster vs Galera Cluster vs MySQL Group ReplicationKenny Gryp
What are the implementation differences between Percona XtraDB Cluster 5.7, Galera Cluster 5.7 and MySQL Group Replication?
- How do each of these work?
- How do they behave differently?
- Are there any major issues with any of these?
This talk will describe these differences and also shed some light on how QA is done for each of these different technologies.

Everything You Need to Know About MySQL Group ReplicationNuno Carvalho
MySQL Group Replication is a new plugin that implements an exciting extension to the proven and long standing MySQL Replication technology. It leverages advanced distributed protocols to ultimately provide to the end user features such as data replication, high availability, split brain protection and automation.
It can be deployed in single-primary mode (default), in which primary fail-over is handled gracefully and automatically, or in multi-master mode, in which row level conflicts are detected and handled automatically as well. Regardless of the deployment mode, the end result is that this new addition provides a consistent and dependable replicated state machine, thus effectively enabling a fault-tolerant MySQL database service.
At the end of the presentation, you will be able to understand how it works, the use cases it address, its limitations and also its roadmap ahead. Moreover, you will get to know how it fits in the overall high availability roadmap at MySQL.
Many questions on database newsgroups and forums can be answered with uses of outer joins. Outer joins are part of the standard SQL language and supported by all RDBMS brands. Many programmers are expected to use SQL in their work, but few know how to use outer joins effectively.
Learn to use this powerful feature of SQL, increase your employability, and amaze your friends!
Karwin will explain outer joins, show examples, and demonstrate a Sudoku puzzle solver implemented in a single SQL query.
Multi Source Replication With MySQL 5.7 @ VerisureKenny Gryp
Verisure, Europe's most popular home alarm with more than 1.8 million customers using the system every day, relies on MySQL for a lot of its customers' data.
Data is stored into a sharded database architecture using MySQL. Some of that data is is being replicated into a centralized data warehouse for business intelligence purposes.
For a long time, Tungsten Replicator has been used to fan-in the data into a single MySQL instance.
This worked well until Verisure expanded. The data growth has increased dramatically ever since, and the architecture began to be difficult to operate.
MySQL 5.7 comes with multi-source replication support out of the box, and as this can simplify the architecture a lot, Verisure became early adopters of MySQL 5.7.
This talk is about being an early MySQL 5.7 adopter. We'll talk about why we did it, how we put it into production, what problems we ran into and what successes we had with MySQL 5.7.
Upgrading MySQL databases do not come without risk. There is no guarantee that no problems will happen if you move to a new major MySQL version.
Should we just upgrade and rollback immediately if problems occur? But what if these problems only happen a few days after migrating to this new version?
You might have a database environment that is risk-adverse, where you really have to be sure that this new MySQL version will handle the workload properly.
Examples:
- Both MySQL 5.6 and 5.7 have a lot of changes in the MySQL Optimizer. It is expected that this improves performance of my queries, but is it really the case? What if there is a performance regression? How will this affect my database performance?
- Also, there are a lot of incompatible changes which are documented in the release notes, how do I know if I'm affected by this in my workload? It's a lot to read..
- Can I go immediately from MySQL 5.5 to 5.7 and skip MySQL 5.6 even though the MySQL documentation states that this is not supported?
- Many companies have staging environments, but is there a QA team and do they really test all functionality, under a similar workload?
This presentation will show you a process, using open source tools, of these types of migrations with a focus on assessing risk and fixing any problems you might run into prior to the migration.
This process can then be used for various changes:
- MySQL upgrades for major version upgrades
- Switching storage engines
- Changing hardware architecture
Additionally, we will describe ways to do the actual migration and rollback with the least amount of downtime.
Designing an extensible, flexible schema that supports user customization is a common requirement, but it's easy to paint yourself into a corner.
Examples of extensible database requirements:
- A database that allows users to declare new fields on demand.
- Or an e-commerce catalog with many products, each with distinct attributes.
- Or a content management platform that supports extensions for custom data.
The solutions we use to meet these requirements is overly complex and the performance is terrible. How should we find the right balance between schema and schemaless database design?
I'll briefly cover the disadvantages of Entity-Attribute-Value (EAV), a problematic design that's an example of the antipattern called the Inner-Platform Effect, That is, modeling an attribute-management system on top of the RDBMS architecture, which already provides attributes through columns, data types, and constraints.
Then we'll discuss the pros and cons of alternative data modeling patterns, with respect to developer productivity, data integrity, storage efficiency and query performance, and ease of extensibility.
- Class Table Inheritance
- Serialized BLOB
- Inverted Indexing
Finally we'll show tools like pt-online-schema-change and new features of MySQL 5.6 that take the pain out of schema modifications.
Caching and tuning fun for high scalability @ FOSDEM 2012Wim Godden
Caching has been a 'hot' topic for a few years. But caching takes more than merely taking data and putting it in a cache : the right caching techniques can improve performance and reduce load significantly. But we'll also look at some major pitfalls, showing that caching the wrong way can bring down your site. If you're looking for a clear explanation about various caching techniques and tools like Memcached, Nginx and Varnish, as well as ways to deploy them in an efficient way, this talk is for you.

While probably the most prominent, Docker is not the only tool for building and managing containers. Originally meant to be a "chroot on steroids" to help debug systemd, systemd-nspawn provides a fairly uncomplicated approach to work with containers. Being part of systemd, it is available on most recent distributions out-of-the-box and requires no additional dependencies.
This deck will introduce a few concepts involved in containers and will guide you through the steps of building a container from scratch. The payload will be a simple service, which will be automatically activated by systemd when the first request arrives.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.
