MySQL InnoDB Cluster / ReplicaSet - TutorialKenny Gryp
Tutorial on MySQL InnoDB Cluster and ReplicaSet, a fully integrated product built on MySQL technology, by MySQL.
MySQL InnoDB Cluster and ReplicaSet provide failover/high availability and scaling features baked in; providing an integrated end-to-end solution that is easy to use.
The document summarizes the results of a proof of concept (POC) comparing the performance of an IBM Power8 system versus an Oracle Exadata X7-2 system for a customer's data warehouse workload. The POC found that while the IBM system was able to increase load speeds by a factor of four, this was achieved through maximizing CPU cores and using outdated optimizer settings, resulting in CPU bottlenecks and errors. In contrast, the Exadata system was able to match the IBM performance using fewer virtual CPUs and default optimizer settings, with low CPU usage and fast I/O times. Further optimizations to the problem queries allowed the Exadata to exceed the IBM performance levels while using fewer resources.

The document aims to provide guidance on areas to optimize to improve MySQL server performance.
This document summarizes a presentation on tuning Oracle GoldenGate for optimal performance in real-world environments. It discusses architectural changes in GoldenGate 12c including a microservices architecture and parallel replication. It also outlines several areas and tools for tuning performance at the host, database, and GoldenGate configuration levels including the use of AWR, STATS commands, and health check scripts.
The document provides an overview of new replication features in MySQL 5.7, including:
1. Online reconfiguration of global transaction identifiers and replication filters which allow changing replication settings without restarting servers or interrupting reads/writes.
2. Online reconfiguration of replication receivers and appliers which enables changing the replication topology during failover without stopping applier threads.
3. Improved replication monitoring through new performance schema tables that provide more accurate and extensive monitoring of replication components.
Replication features, technologies and 3rd party ExtinctionBen Mildren
The document discusses MySQL replication features, technologies, and third party tools for replication. It covers MySQL native replication, topologies, and the ecosystem of additional replication products and tools that complement or improve upon native replication. These include solutions for data consistency, performance, monitoring, and high availability.
MySQL Fabric is an open-source framework for the management of farms of servers. It is designed to be easy to use and available for both small and large server farms.
In order to create a solution that is truly resilient to failures, it is necessary to ensure redundancy of every component in the system and have a solid foundation for detecting and handling failures.
In this session, you will learn how to build a robust
high-availability solution using MySQL Fabric, what components you need and how they should be set up. You will learn how MySQL Fabric handles high-availability of the application servers and how to ensure high-availability of the Fabric system as a whole. You will also learn how to leverage, for example, OpenStack to ensure that the system keeps operating in the presence of failures.

MySQL High Availability Solutions - Feb 2015 webinarAndrew Morgan
How important is your data? Can you afford to lose it? What about just some of it? What would be the impact if you couldn’t access it for a minute, an hour, a day or a week?
Different applications can have very different requirements for High Availability. Some need 100% data reliability with 24x7x365 read & write access while many others are better served by a simpler approach with more modest HA ambitions.
MySQL has an array of High Availability solutions ranging from simple backups, through replication and shared storage clustering – all the way up to 99.999% available shared nothing, geographically replicated clusters. These solutions also have different ‘bonus’ features such as full InnoDB compatibility, in-memory real-time performance, linear scalability and SQL & NoSQL APIs.
The purpose of this presentation is to help you decide where your application sits in terms of HA requirements and discover which of the MySQL solutions best fit the bill. It will also cover what you need outside of the database to ensure High Availability – state of the art monitoring being a prime example.
MySQL Scalability and Reliability for Replicated EnvironmentJean-François Gagné
You have a working application that is using MySQL: great! At the beginning, you are probably using a single database instance, and maybe – but not necessarily – you have replication for backups, but you are not reading from slaves yet. Scalability and reliability were not the main focus in the past, but they are starting to be a concern. Soon, you will have many databases and you will have to deal with replication lag. This talk will present how to tackle the transition.
We mostly cover standard/asynchronous replication, but we will also touch on Galera and Group Replication. We present how to adapt the application to become replication-friendly, which facilitate reading from and failing over to slaves. We also present solutions for managing read views at scale and enabling read-your-own-writes on slaves. We also touch on vertical and horizontal sharding for when deploying bigger servers is not possible anymore.
Are UNIQUE and FOREIGN KEYs still possible at scale, what are the downsides of AUTO_INCREMENTs, how to avoid overloading replication, what are the limits of archiving, … Come to this talk to get answers and to leave with tools for tackling the challenges of the future.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
