MySQL Fabric now Generally Available – Automating High Availability and Sharding for MySQL
Employee +5 Vote Up -0Vote Down


MySQL Fabric is a new framework that automates High Availability (HA) and/or sharding (scaling-out) for MySQL and it has just been declared Generally Available.

This post focuses on MySQL Fabric as a whole – both High Availability and scaling out (sharding). It starts with an introductions to HA and scaling out (by partitioning/sharding data) and how MySQL Fabric achieves it before going on to work through a full example of deploying HA with MySQL Fabric and then adding sharding on top.

MySQL Cluster 7.4.0 Labs Release
Employee +3 Vote Up -0Vote Down

The first version of MySQL Cluster 7.4 has now been released on MySQL Labs. Note that labs loads are not suitable for production use (in fact they’re even less mature than Development Milestone Releases); their purpose is to give users a chance to see what’s in the works, try it for themselves and then provide feedback. Having read that, if you’d like to try it out then Download MySQL Cluster 7.4 from MySQL Labs.

The focus of this first Cluster 7.4 load is performance and data node restart

MySQL Fabric is a new framework that adds High Availability (HA) and/or scaling-out for MySQL. MySQL Fabric achieves scale-out by managing the sharding of table data between multiple MySQL Servers and then having Fabric-aware connectors route queries and transactions to the correct locations – scaling-out will be the subject of a future post and the rest of this article is focused on using MySQL Fabric for HA. It starts with an introduction to HA and how MySQL Fabric delivers it before going on to work through a full example of configuring a HA farm of MySQL Servers together with the code that the

MySQL Fabric is a very promising sharding framework. If I take Ulf Wendel definition of MySQL Fabric :

Percona XtraDB Cluster (PXC) itself manages quorum and node failure.  Minorities of nodes in a network partition situation will move themselves into a Non-primary state and not allow any DB activity.  Nodes in such a state will be easily detectable via SHOW GLOBAL STATUS variables.

It’s common to use HAproxy with PXC for load balancing purposes, but what if you are

MySQL Cluster Asynchronous Replication – conflict detection & resolution
Employee +3 Vote Up -0Vote Down

I was rooting through past blog entries and I stumbled accross a draft post on setting up multi-master (update anywhere) asynchronous replication for MySQL Cluster. The post never quite got finished and published and while the material is now 4 years old it may still be helpfull to some and so I’m posting it now. Note that a lot has happened with MySQL Cluster in the last 4 years and in this area, the most notable change has been the Enhanced conflict resolution with MySQL Cluster active-active replication feature introduced in MySQL Cluster 7.2 and if you’re only dealing with a pair of Clusters, that’s your best option as it removed the need for you

PoC: Using a Group Communication System (Isis2) to improve MySQL Replication HA
Employee +2 Vote Up -0Vote Down

Modern NoSQL solutions make good, old MySQL Replication appear weak on High Availability (HA). Basically, MySQL users have three choices for MySQL Replication HA: give up on HA, believe that doubling single points of failures means HA, or go for a proper but complex solution. Albeit, as NoSQL world and competition proves, solid HA can be dead simple: embed a Group Communication System (GCS) into MySQL! No single point of failure and near zero client deployment is doable. In parts, the proposal surpassed Pacemaker/Corosync. Read on: story, slides, experimental code.

MySQL Replication: Self-Healing Recovery with GTIDs and MySQL Utilities
Employee_Team +2 Vote Up -0Vote Down

MySQL 5.6 includes a host of enhancements to replication (http://www.mysql.com/products/enterprise/replication.html), enabling DevOps teams to reliably scale-out their MySQL infrastructure across commodity hardware, on-premise or in the cloud.

One of the most significant enhancements is the introduction of Global Transaction Identifiers (GTIDs) where the primary development motivation was:

- enabling seamless failover or switchover from a replication master to slave

- promoting that slave to the new master

- without manual intervention and with minimal service disruption.

MySQL 5.6 Replication: New Resources for Database Scaling and HA
Employee_Team +8 Vote Up -0Vote Down
MySQL 5.6 reached GA (General Availability) today and is packed with a wealth of new features and capabilities.  Exciting stuff!
MySQL 5.6 also introduces the largest set of enhancements to replication ever delivered in a single release, including: - 5x higher performance to improve consistency across a cluster and reduce the risks of data loss in the event of a master failing - Self-healing clusters with automatic failover and recovery from outages or planned maintenance - Assured data integrity with checksums implemented across the replication workflow - DevOps automation
Of course, getting started with all of these enhancements can be a challenge - whether you are new to MySQL replication or an experienced user. So two new Guides are available to help take advantage of

Deep Dive into GTIDs and MySQL 5.6 - What, Why and How
Employee_Team +6 Vote Up -0Vote Down

Global Transaction Identifiers (GTIDs) are one of the key replication enhancements in MySQL 5.6. GTIDs make it simple to track and compare replication across a master - slave topology. This enables:

- Much simpler recovery from failures of the master,

- Introduces great flexibility in the provisioning and on-going management of multi-tier or ring (circular) replication topologies.

A new on-demand MySQL 5.6 GTID webinar (http://www.mysql.com/news-and-events/web-seminars/mysql-replication-simplifying-scaling-and-ha-with-gtids/) delivered by the replication engineering team is now available, providing deep insight into the design and implementation of GTIDs, and how they enable users to simplify MySQL scaling and HA.

Within hours of my post about meeting the MySQL community in Barcelona, we got several offers to help, and within one day, an event was created and agreed upon.

Thanks!

Today the event was posted at Evenbrite. It will take place on Tuesday, November 13th, at 7pm. It will be a one hour talk about State of the art in MySQL high availability and replication, followed by one hour of Q&A, networking, beer, and snacks.

Registration is necessary, because the seats are limited. If you want to attend, you should register as soon as possible!

New Options for MySQL High Availability
Employee_Team +2 Vote Up -0Vote Down

Data is the currency of today’s web, mobile, social, enterprise and cloud applications. Ensuring data is always available is a top priority for any organization – minutes of downtime will result in significant loss of revenue and reputation.

There is not a “one size fits all” approach to delivering High Availability (HA). Unique application attributes, business requirements, operational capabilities and legacy infrastructure can all influence HA technology selection. And then technology is only one element in delivering HA – “People and Processes” are just as critical as the technology itself.

For this reason, MySQL Enterprise Edition (http://www.mysql.com/products/enterprise/) is available supporting a range of HA solutions, fully certified and supported by Oracle. MySQL Enterprise HA
