MySQL Group Replicatio in a nutshell - MySQL InnoDB Cluster

MySQL InnoDB Cluster provides a complete high availability solution for MySQL. MySQL Shell includes AdminAPI which enables you to easily configure and administer a group of at least three MySQL server instances to function as an InnoDB cluster. This talk includes best practices.

The document discusses MySQL Group Replication, which is a plugin that provides multi-master replication capability for MySQL. It allows data to be replicated between multiple MySQL servers so that they can stay in sync. The replication works by having each server send transaction writesets to other servers through a group communication system, and then each server certifies and applies the changes locally in an asynchronous manner.

Verisure migrated their data warehouse from using Tungsten Replicator to native multi-source replication in MySQL 5.7 to simplify operations. They loaded data from production shards into the new data warehouse setup using XtraBackup backups and improved replication capacity with MySQL's parallel replication features. Some issues were encountered with replication lag reporting and crashes during the upgrade but most were resolved. Monitoring and management tools also required updates to support the new multi-source replication configuration.

The document provides an overview of MySQL Group Replication, which is a multi-master update anywhere replication plugin for MySQL that provides built-in automatic distributed recovery, conflict detection, and group membership. It allows for active/active update anywhere setups, automates group reconfiguration, and provides a highly available distributed database service. The document discusses the theory behind MySQL Group Replication, provides examples of how to use it, and concludes by discussing its benefits and future releases.

This allows users to test an Oracle 12c RAC sandbox environment locally without requiring additional physical hardware.

This document provides an overview and comparison of MySQL InnoDB Cluster and MySQL InnoDB ReplicaSet. It discusses the components, goals, and features of each solution. MySQL InnoDB Cluster uses Group Replication to provide high availability, automatic failover, and data consistency. MySQL InnoDB ReplicaSet uses asynchronous replication and provides availability and read scaling through manual primary/secondary configuration and failover. Both solutions integrate MySQL Shell, Router, and automatic member provisioning for easy management.

MySQL InnoDB cluster provides a complete high availability solution for MySQL. MySQL Shell includes AdminAPI which enables you to easily configure and administer a group of at least three MySQL server instances to function as an InnoDB cluster. Each MySQL server instance runs MySQL Group Replication, which provides the mechanism to replicate data within InnoDB clusters, with built-in failover. MySQL Router can automatically configure itself based on the cluster you deploy, connecting client applications transparently to the server instances.

The document discusses asynchronous MySQL replication and its limitations. Asynchronous replication involves replicas streaming replication logs from a single master, which can lead to lag. Replica provisioning and data consistency must be manually handled. Complex replication topologies can be built but come with challenges around write safety and management overhead. Group replication aims to address some of these issues.

Group Replication went Generally Available end of 2016, it introduces a 'synchronous' active:active multi-master eplication, in addition to asynchronous and semi-synchronous replication, the latter 2 being available in in MySQL for longtime. As with any new feature, and especially with introducing active:active multi-master replication, it takes a while before companies are adopting the software in production database environment. For example, even though MySQL 5.7 has been GA for more than a year, adoption is only starting to increase recently. We can, and should, expect the same from Group Replication. As with every release, bugs will be found, and with new features, best practises still need to formed out of practical experience. After giving a short introduction on what Group Replication is, I will cover my experience so far in evaluating Group Replication.

Pre-FOSDEM 2020 talk about how latency in Cloud deployments can affect MySQL performance, and Replication in particular.

The document discusses using ProxySQL as a solution for anonymizing data in MySQL databases. It describes how ProxySQL can mask specific columns by replacing values with partial values and characters like X.

MySQL Group Replication is a new 'synchronous', multi-master, auto-everything replication plugin for MySQL introduced with MySQL 5.7. It is the perfect tool for small 3-20 machine MySQL clusters to gain high availability and high performance. It stands for high availability because the fault of replica don't stop the cluster. Failed nodes can rejoin the cluster and new nodes can be added in a fully automatic way - no DBA intervention required. Its high performance because multiple masters process writes, not just one like with MySQL Replication. Running applications on it is simple: no read-write splitting, no fiddling with eventual consistency and stale data. The cluster offers strong consistency (generalized snapshot isolation). It is based on Group Communication principles, hence the name.

This document discusses automating database schema changes and migrations. It introduces the MySQL Utilities and Percona Toolkit tools that can be used to compare and synchronize database schemas. It then describes an online-migration.py script that uses these tools to automate schema migrations in a way that can be integrated with Puppet for infrastructure automation. The script allows rolling back migrations, checking the schema version and differences, and performing migrations without blocking reads or writes to the database.

This document outlines Oracle's general product direction for MySQL and includes the following key points: 1. The information is for informational purposes only and does not represent a commitment to deliver features. 2. Oracle has sole discretion over the development, release, and timing of product features. 3. The presentation discusses MySQL's support for DevOps practices through features like InnoDB Cluster for high availability, Group Replication for multi-master replication, MySQL Shell for administration, and persisting configuration variables.

The document discusses how database administrators (DBAs) can adopt a devops approach to their work. It recommends that DBAs focus on communication, configuration management, testing, and visibility. Specific techniques mentioned include using Puppet for infrastructure automation, monitoring with tools like Cacti and Percona plugins, and collaborating with developers and sysadmins on projects from start to finish using practices like continuous integration. The goal is to align DBA work more closely with devops principles of collaboration, automation, and transparency.

MySQL Group Replication provides a high availability multi-master replication solution for MySQL. It allows multiple MySQL instances to act as equal masters that can accept writes and remain available even if some instances fail. Transactions are synchronously committed across all members of the replication group to ensure consistency. Group Replication handles failure detection and recovery transparently through its use of group communication systems and built-in conflict detection. It provides a highly available, scalable and fully distributed database solution compared to traditional MySQL replication and clustering options.

MySQL Group Replication is a plugin that enables multi-master replication. It allows any server in the replication group to accept writes and provides automatic recovery from failures or new servers joining. It uses message passing and conflict detection to keep all servers in sync. The plugin manages the distributed transaction execution and recovery process.

This document provides an overview of advanced MySQL replication techniques. It begins with an introduction to replication basics like principles, setup, and monitoring. It then discusses challenges with replication including master switchovers during failures and slaves falling behind. The document outlines various replication power techniques and features that can help address these issues like row-based and semi-synchronous replication. It also covers tools for replication and techniques for replication outside of the traditional setup.

This document discusses how database administrators (DBAs) can adopt a DevOps approach to their work. It suggests DBAs focus on communication, configuration management, testing, and visibility/monitoring. Some specific DevOps practices for DBAs include: discussing database designs with developers and sysadmins; treating schema changes like code migrations; automating configurations with tools like Puppet; integrating database testing; and sharing monitoring dashboards. The overall goal is for DBAs, developers and sysadmins to work as a collaborative "DevDBAOps" team with improved communication and feedback loops.

Multi-primary mode is also demonstrated. - Status variables and queries are shown to identify the current primary node.

MySQL Group Replication is the heart of MySQL InnoDB Cluster, the new HA solution for MySQL. How does it work ?

The document discusses MySQL InnoDB Cluster, which provides high availability and scaling features for MySQL. It uses Group Replication under the hood, which allows data to be written simultaneously across cluster nodes while maintaining consistency. By default, MySQL InnoDB Cluster runs in Single Primary Mode, where one node acts as the primary/writable node and others act as hot standbys through an automated leader election process.

The document discusses migrating from a master-slave MySQL configuration to a MySQL InnoDB Cluster. The plan involves: 1) Taking a hot backup of the current slave and restoring it on a new server; 2) Configuring the new server as an asynchronous slave; 3) Creating an initial InnoDB Cluster with the new server; 4) Stopping replication on the original slave and joining it to the cluster; 5) Optionally adding the original master to the cluster to enable high availability.

Since the introduction of replication in MySQL, users have been trying to automate the promotion of a replica to a primary as well as automating the failover of TCP connections from one database server to another in the event of a database failure: planned or unplanned. For over a decade, users and organizations have designed various types of solutions to achieve this. Though, many of these solutions were done manually or were using third party software, mostly open source, to automate and integrate various architectures. For more than 5 years now, MySQL offers complete and very easy-to-use solutions to set up database architectures that provide High-Availability and recently added Disaster Recovery capabilities. Completely built in-house and supported by Oracle, many enterprises large and small have adopted these solutions into business-critical applications. Business requirements dictate what type of database architecture is required for your system. Disaster tolerance is key and can be measured at different levels: data loss, data availability, and uptime. In this session, the various MySQL Database Architecture solutions will be covered to help you choose the right solution based on your business requirements

From a single MySQL instance to multi-site high availability, this is what you will find out in this presentation. You will learn how to make this transition and which solutions best suit changing business requirements (RPO, RTO). Recently, MySQL has extended the possibilities for easy deployment of architecture with integrated tools. Come and discover these open source solutions that are part of MySQL.

In this tutorial, we cover the different deployment possibilities of the MySQL architecture depending on the business requirements for the data. We also deploy some architecture and see how to evolve to the next one. The tutorial covers the new MySQL Solutions like InnoDB ReplicaSet, InnoDB Cluster, and InnoDB ClusterSet.

At the beginning of a project, the database is just a single MySQL instance (maybe not even running on its own hardware)... but with the evolution of the business requirements, the database must change to also meet the new targets of data loss and uptime. During this session we will follow the journey of a single MySQL server from the simple instance to a High Available Architecture with multi-site Disaster Recovery. We will discover easy manageable native solutions like MySQL InnoDB ReplicaSet, MySQL InnoDB Cluster and MySQL InnoDB ClusterSet. The session is also illustrated with commands and examples.

Nobody complains that the database is too fast. But when things slow down, the complaints come quickly. The two most popular approaches to speeding up queries are indexes and histograms. But there are so many options and types on indexes that it can get confusing. Histograms are fairly new to MySQL but they do not work for all types of data. This talk covers how indexes and histograms work and show you how to test just how effective they are so you can measure the performance of your queries.

Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality. Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality. Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality. Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank? ** Episode Overview ** In this first episode of our quality series, Kristen Hansen and the panel discuss: ⦿ What do we mean when we say patent quality? ⦿ Why is patent quality important? ⦿ How to balance quality and budget ⦿ The importance of searching, continuations, and draftsperson domain expertise ⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications https://www.aurorapatents.com/patently-strategic-podcast.html

This is a slide deck that showcases the updates in Microsoft Copilot for May 2024

Have you noticed the OpenSSF Scorecard badges on the official Dart and Flutter repos? It's Google's way of showing that they care about security. Practices such as pinning dependencies, branch protection, required reviews, continuous integration tests etc. are measured to provide a score and accompanying badge. You can do the same for your projects, and this presentation will show you how, with an emphasis on the unique challenges that come up when working with Dart and Flutter. The session will provide a walkthrough of the steps involved in securing a first repository, and then what it takes to repeat that process across an organization with multiple repos. It will also look at the ongoing maintenance involved once scorecards have been implemented, and how aspects of that maintenance can be better automated to minimize toil.
