Not too long ago, a reactive variant of the JDBC driver was released, known as Reactive Relational Database Connectivity (R2DBC for short). While R2DBC started as an experiment to enable integration of SQL databases into systems that use reactive programming models, it now specifies a full-fledged service-provider interface that can be used to retrieve data from a target data source. In this session, we’ll take a look at the new MariaDB R2DBC connector and examine the advantages of fully reactive, non-blocking development with MariaDB. And, of course, we’ll dive in and get a first-hand look at what it’s like to use the new connector with some live coding!

Much industry focus is on All-Flash Arrays with traditional databases, but new databases using native direct-attached Flash have proven reliable, performant, and popular for operational use cases. Today, these operational databases store account information for banking and retail applications, real-time routing information for telecoms, and user profiles for advertising; they also support machine learning for applications in the financial industry, such as fraud detection. While proprietary PCIe and “wide SATA” had previously been popular, NVMe has finally come into operational use. Aerospike will discuss the benefits of NVMe for these use cases (including specific configurations and performance numbers), as well as the architectural implications of low-latency Flash and Storage Class Memory.

Orwell Group shares how they leveraged microservices, an event driven architecture and both master and reference data management methodologies to build a new banking system for high retail banking customers and corporate banks requiring cross border payments and cash flow management – and scaled it to handle customers with millions of clients. In particular they explain how they built a high availability, geo-distributed and consistent platform on top of MariaDB. The result was a secure and distributed platform with high cost efficiency, and the data accuracy and consistency needed to create high quality data pipelines from transactions to analytics and ensure regulatory compliance (e.g., GDPR).

Join Laurent Blume, Unix Systems Engineer & PCI Specialist and Vinay Joosery, CEO at Severalnines, as they discuss all there is to know about how to achieve PCI compliance for MySQL & MariaDB with ClusterControl. The Payment Card Industry Data Security Standard (PCI-DSS) is a set of technical and operational requirements defined by the PCI Security Standards Council (PCI SSC) to protect cardholder data. These standards apply to all entities that store, process or transmit cardholder data – with requirements for software developers and manufacturers of applications and devices used in those transactions. PCI data that resides in a MySQL or MariaDB database must of course also adhere to these requirements, and database administrators must follow best practices to ensure the data is secured and compliant. The PCI standards are stringent and can easily require a spiraling amount of time spent on meeting their requirements. Database administrators can end up overwhelmed when using software that was not designed for compliance, often because it long predates PCI itself, as is the case for most database systems in use today. That is why, as often as possible, reliable tools must be chosen to help with that compliance, easing out the crucial parts. Each time the compliance for one requirement can be shown to be implemented, working, and logged accordingly, time will be saved. If well-designed, it will only require regular software upgrades, a yearly review and a moderate amount of tweaking to follow the standard's evolution over time. This webinar focuses on PCI-DSS requirements for a MySQL or MariaDB database back-end managed by ClusterControl in order to help meet these requirements. It will provide a MySQL and MariaDB user focussed overview of what the PCI standards mean, how they impact database management and provide valuable tips and tricks on how to achieve PCI compliance for MySQL & MariaDB with ClusterControl.

The NotPetya, SolarWinds, and Kaseya cybersecurity attacks were all executed by injection of malicious code in software shipped by vendors to thousands of companies. These attacks have made the public more aware of the importance of secure software supply chains. But the path from awareness to ensuring a secure supply chain is long. Developers have gotten used to the convenience of easily downloading third party software into containers, and it is challenging to tighten supply chain security in a company with a sprawl of open source components. Scling is a small data engineering startup, and since we ask our customers to entrust us with their data, we must take security seriously. We have been securing our software supply chain since the company was founded. We have no venture capital, and our customers expect quick development iteration cycles, so we have solved supply chain security with minimal effort and minimal impact on developer productivity. In this presentation, we share how we have addressed the different supply chain attack vectors, e.g. Python and JVM packages, with technical solutions. We will present how we automate third party software upgrades to stay up to date with security upgrades while minimising the risk of downloading rogue code.

Backup and restore methods are concepts that everyone knows the importance of. Over the years, open-source tools emerged like MyDumper, Xtrabackup, and Mariabackup. Also, with MySQL 8 new shell, new utils for dump and restore were introduced as well. In this presentation, we are going to compare the newest backup/restore methods with the most used ones. We will see how parallelization can influence the speed of backup and restore process and also how the compression algorithms can influence the performance. In this talk, we will compare mysqldump, mydumper/myloader, mysqlpump, MySQL Shell utils, and Xtrabackup.

Join us as the Severalnines & Percona teams join forces for a different perspective on how to automate and manage your MongoDB or Percona Server for MongoDB databases. During this webinar, we’ll walk you through the key features of the Percona Server for MongoDB as compared to MongoDB itself as well as how to manage both “flavours” of MongoDB. There are many generic tools available, both commercial and open source, to aid with the automation of operational tasks. Some of these tools are even deployed in the database world. However, there are a small number of specialist domain-specific automation tools available, and we are going to compare the MongoDB-relevant functionality of two of these products: MongoDB’s Ops Manager, and ClusterControl from Severalnines. Attendees should take away a clear understanding of the differences between these tools, and how they help automate and manage MongoDB operations. AGENDA - Introduction to Percona Server for MongoDB - How to automate and manage MongoDB - Installation and maintenance - Complexity of architecture - Options for redundancy - Comparative functionality - Monitoring, Dashboard, Alerting - Backing up your deployments - Automated deployment of advanced configurations - Upgrading existing deployments SPEAKERS Ruairí Newman is passionate about all things cloud and automation and has worked for MongoDB, VMware and Amazon Web Services among others. He has a background in Operational Support Systems and Professional Services. Prior to joining Severalnines, Ruairí worked for Huawei Ireland as Senior Cloud Solutions Architect on their Web Services project, where he advised on commodity cloud architecture and Monitoring technologies, and deployed and administered a Research & Development Openstack lab. Prior to joining Percona as a Product Manager, Tyler Duzan spent almost 13 years as an operations and security engineer in a variety of different industries. Deciding to take his analytical mindset and strategic focus into new territory, Tyler is applying his knowledge to solving business problems for Percona customers with inventive solutions combining technology and services.

MySQL 5.7 will reach its End Of Life in October 2023. This means that there will be no releases after that date, no bug fixes, and no security fixes. The documentation will be withdrawn and will no longer be available at some point. Official and non-official drivers and tools will, sooner or later, stop supporting MySQL 5.7. From here, 5.7 users have two paths. They can upgrade to MySQL 8.0, or they can move to MariaDB. Each option has its benefits and its drawbacks. In this webinar we will explore the differences between MySQL 8.0 and MariaDB 10.11 or 10.6, from both a technical and a less technical perspective.

Over the past few years, VidaXL has become a European market leader in the online retail of slow moving consumer goods. When a company achieved over 50% year over year growth for the past 9 years, there is hardly enough time to overhaul existing systems. This means existing systems will be stretched to the maximum of their capabilities, and often additional performance will be gained by utilizing a large variety of datastores.

Failover is the process of moving to a healthy standby component, during a failure or maintenance event, in order to preserve uptime. The quicker it can be done, the faster you can be back online. However, failover can be tricky for transactional database systems as we strive to preserve data integrity - especially in asynchronous or semi-synchronous topologies. There are risks associated, from diverging datasets to loss of data. Failing over due to incorrect reasoning, e.g., failed heartbeats in the case of network partitioning, can also cause significant harm. This webinar replay gives a detailed overview of what failover processes may look like in MySQL, MariaDB and PostgreSQL replication setups. We’ve covered the dangers related to the failover process, and discuss the tradeoffs between failover speed and data integrity. We’ve found out about how to shield applications from database failures with the help of proxies. And we've finally had a look at how ClusterControl manages the failover process, and how it can be configured for both assisted and automated failover. So if you’re looking at minimizing downtime and meet your SLAs through an automated or semi-automated approach, then this webinar replay is for you! AGENDA - An introduction to failover - what, when, how - in MySQL / MariaDB - in PostgreSQL - To automate or not to automate - Understanding the failover process - Orchestrating failover across the whole HA stack - Difficult problems - Network partitioning - Missed heartbeats - Split brain - From assisted to fully automated failover with ClusterControl - Demo SPEAKER Krzysztof Książek, Senior Support Engineer at Severalnines, is a MySQL DBA with experience managing complex database environments for companies like Zendesk, Chegg, Pinterest and Flipboard.

Krzysztof Ksiazek - Severalnines AB So, you are a developer or sysadmin and showed some abilities in dealing with databases issues. And now, you have been elected to the role of DBA. And as you start managing the databases, you wonderâ€¦ * How do I tune them to make best use of the hardware? * How do I optimize the Operating System? * How do I best configure MySQL or MariaDB for a specific database workload? If you're asking yourself the following questions when it comes to optimally running your MySQL or MariaDB databases, then this talk is for you! We will discuss some of the settings that are most often tweaked and which can bring you significant improvement in the performance of your MySQL or MariaDB database. We will also cover some of the variables which are frequently modified even though they should not. Performance tuning is not easy, especially if you're not an experienced DBA, but you can go a surprisingly long way with a few basic guidelines.

To operate PostgreSQL efficiently, you need to have insight into database performance and make sure it is at optimal levels. With that in mind, we dive into monitoring PostgreSQL for performance in this webinar replay. PostgreSQL offers many metrics through various status overviews and commands, but which ones really matter to you? How do you trend and alert on them? What is the meaning behind the metrics? And what are some of the most common causes for performance problems in production? We discuss this and more in ordinary, plain DBA language. We also have a look at some of the tools available for PostgreSQL monitoring and trending; and we’ll show you how to leverage ClusterControl’s PostgreSQL metrics, dashboards, custom alerting and other features to track and optimize the performance of your system. AGENDA - PostgreSQL architecture overview - Performance problems in production - Common causes - Key PostgreSQL metrics and their meaning - Tuning for performance - Performance monitoring tools - Impact of monitoring on performance - How to use ClusterControl to identify performance issues - Demo SPEAKER Sebastian Insausti, Support Engineer at Severalnines, has loved technology since his childhood, when he did his first computer course (Windows 3.11). And from that moment he was decided on what his profession would be. He has since built up experience with MySQL, PostgreSQL, HAProxy, WAF (ModSecurity), Linux (RedHat, CentOS, OL, Ubuntu server), Monitoring (Nagios), Networking and Virtualization (VMWare, Proxmox, Hyper-V, RHEV). Prior to joining Severalnines, Sebastian worked as a consultant to state companies in security, database replication and high availability scenarios. He’s also a speaker and has given a few talks locally on InnoDB Cluster and MySQL Enterprise together with an Oracle team. Previous to that, he worked for a Mexican company as chief of sysadmin department as well as for a local ISP (Internet Service Provider), where he managed customers' servers and connectivity. This webinar builds upon a related blog post by Sebastian: https://severalnines.com/blog/performance-cheat-sheet-postgresql.

Database availability is notoriously hard to measure and report on, although it is an important KPI in any SLA between you and your customer. We often define availability in terms of 9’s (e.g. 99.9% or 99.999%), although there is often a lack of understanding of what these numbers might mean, or how we can measure them. Is the database available if an instance is up and running, but it is unable to serve any requests? Or if response times are excessively long, so that users consider the service unusable? Is the impact of one longer outage the same as multiple shorter outages? How do partial outages affect database availability, where some users are unable to use the service while others are completely unaffected? Not agreeing on precise definitions with your customer might lead to dissatisfaction. The database team might be reporting that they have met their availability goals, while the customer is dissatisfied with the service. In this webinar, we will discuss the different factors that affect database availability. We will then see how you can measure your database availability in a realistic way. AGENDA - Defining availability targets - Critical business functions - Customer needs - Duration and frequency of downtime - Planned vs unplanned downtime - SLA - Measuring the database availability - Failover/Switchover time - Recovery time - Upgrade time - Queries latency - Restoration time from backup - Service outage time - Instrumentation and tools to measure database availability: - Free & open-source tools - CC's Operational Report - Paid tools SPEAKER Bartlomiej Oles is a MySQL and Oracle DBA, with over 15 years experience in managing highly available production systems at IBM, Nordea Bank, Acxiom, Lufthansa, and other Fortune 500 companies. In the past five years, his focus has been on building and applying automation tools to manage multi-datacenter database environments.

Docker is becoming more mainstream and adopted by users as a method to package and deploy self-sufficient applications in primarily stateless Linux containers. It's a great toolset on top of OS-level virtualization (LXC, a.k.a containers) and plays well in the world of micro services. However, Docker containers are transient by default. If a container is destroyed, all data created is also lost. For a stateful service like a database, this is a major headache to say the least. There are a number ways to provide persistent storage in Docker containers. In this presentation, we will talk about how to setup a persistence data service with Docker that can be torn down and brought up across hosts and containers. We will touch upon orchestration tools, shared volumes, data-only-containers, security and configuration management, multi-host networking, service discovery and implications on monitoring when we move from host-centric to role-centric services with shorter life cycles.

In any busy operations environment, there are countless tasks to perform - some monthly, or weekly, some daily or more frequently, and some on an ad-hoc basis. And automation is key to performing fast, efficient and consistently repeatable software deployments and recovery. There are many generic tools available, both commercial and open source, to aid with the automation of operational tasks. Some of these tools are even deployed in the database world. However, there are a small number of specialist domain-specific automation tools available also, and we are going to compare two of these products: MongoDB?s own Ops Manager, and ClusterControl from Severalnines. We will cover: * Installation and maintenance * Complexity of architecture * Options for redundancy * Comparative functionality * Monitoring, Dashboard, Alerting * Backing up and restoring * Automated deployment of advanced configurations * Upgrading existing deployments Participants should take away a clear understanding of the differences between these tools, and how they help automate and manage MongoDB operations.

Load balancing MySQL connections and queries using HAProxy has been popular in the past years. Recently however, we have seen the arrival of MaxScale, MySQL Router, ProxySQL and now also Nginx as a reverse proxy. For which use cases do you use them and how well do they integrate in your environment? This session aims to give a solid grounding in load balancer technologies for MySQL and MariaDB. We will review the main open-source options available: from application connectors (php-mysqlnd, jdbc), TCP reverse proxies (HAproxy, Keepalived, Nginx) and SQL-aware load balancers (MaxScale, ProxySQL, MySQL Router). We will also look into the best practices for backend health checks to ensure load balanced connections are routed to the correct nodes in several MySQL clustering topologies. You'll gain a good understanding of how the different options compare, and enough knowledge to decide which ones to explore further.

Proxies are building blocks of high availability setups for MySQL. They can detect failed nodes and route queries to hosts which are still available. If your master failed and you had to promote one of your slaves, proxies will detect such topology changes and route your traffic accordingly. More advanced proxies can do much more, such as route traffic based on precise query rules, cache queries or mirror them. They can be even used to implement different types of sharding. In this webinar we talk about support for proxies for MySQL HA setups in ClusterControl: how they differ and what their pros and cons are. And we show you how you can easily deploy and manage HAProxy, MaxScale and ProxySQL from ClusterControl during a live demo. AGENDA Introduction Why use a proxy layer? Comparison of proxies - the pros & cons - HAProxy - MaxScale - ProxySQL Live demo of proxy support in ClusterControl SPEAKER Krzysztof Książek, Senior Support Engineer at Severalnines, is a MySQL DBA with experience managing complex database environments for companies like Zendesk, Chegg, Pinterest and Flipboard.

AI/ML Infra Meetup May. 23, 2024 Organized by Alluxio For more Alluxio Events: https://www.alluxio.io/events/ Speaker: - Junchen Jiang (Assistant Professor of Computer Science, @University of Chicago) Prefill in LLM inference is known to be resource-intensive, especially for long LLM inputs. While better scheduling can mitigate prefill’s impact, it would be fundamentally better to avoid (most of) prefill. This talk introduces our preliminary effort towards drastically minimizing prefill delay for LLM inputs that naturally reuse text chunks, such as in retrieval-augmented generation. While keeping the KV cache of all text chunks in memory is difficult, we show that it is possible to store them on cheaper yet slower storage. By improving the loading process of the reused KV caches, we can still significantly speed up prefill delay while maintaining the same generation quality.

Scenarios are the central artifact of the Behaviour Driven Development (BDD) process. Although many teams use scenarios and tools like Cucumber or SpecFlow to automate them, in many cases their scenarios contain a lot of details, particularly test data, and therefore they become too complicated to support collaboration with the business. The "essential" principle of scenario writing (scenario formulation) states that only those details should be included in the scenario that are relevant for the outcome. This talk provides help for those who struggle implementing this principle or would be interested to learn how you can create brief and maintainable scenarios.
