Feed: Planet MySQL; Author: Jean-François Gagné; This is a follow-up post in the MySQL Master Replication Crash Safety series.  In the previous posts, we explored the consequences of reducing durability on masters (different data inconsistencies after an OS crash depending on replication type) and the performance boost associated with this configuration (benchmark results done on Google Cloud Platform / GCP).  The consequences are summarised in the introduction of Part #4, and the tests are the subject of this last post.  Also in this last post, I mentioned that my results for high durability are limited by the sync latencies of GCP ...

Feed: Planet MySQL; Author: Jean-François Gagné; This post is a sister post to MySQL Master Replication Crash Safety Part #5: making things faster without reducing durability.  There is no introduction or conclusion to this post, only landing sections: reading this post without its context is not not recommended. You should start with the main post and come back here for more details. And this Part #5 of the series has many sub-parts.  So far, the following has been published:Making things faster without reducing durability - using better hardware I will edit this post as I am publishing the next sub-parts because I prefer ...

Feed: Microsoft Azure Blog. Author: Ziv Rafalovich. Co-locate your Azure resources for improved application performance The performance of your applications is central to the success of your IT organization. Application performance can directly impact your ability to increase customer satisfaction and ultimately grow your business. Many factors can affect the performance of your applications. One of those is network latency which is impacted, among other things, by the physical distance between the virtual machines deployed. For example, when you place your Microsoft Azure Virtual Machines in a single Azure region, the physical distance between the virtual machines is reduced. Placing ... Read More

Feed: Planet MySQL; Author: MinervaDB; Table of Contents Delayed Replication – You can deliberately execute transactions later than the master by a specific duration of time , Why you do that and for what ? Consider this, Accidentally someone did a wrong UPDATE / DELETE in the master and the transaction is committed, Now how can DBA rollback the database system to the last known good condition ? This is when we benefit from MySQL delayed slave replication investment. The default replication delay in MySQL is “0” seconds, To delay the slave by N seconds use the CHANGE MASTER TO MASTER_DELAY = ... Read More

Feed: Planet MySQL; Author: Codership; Do you want to run Galera Cluster in the cloud? Why not learn to setup a 3-node Galera Cluster using Amazon Web Services (AWS) Elastic Compute Cloud (EC2), and run it yourself (3-node because this is the minimum preferred size; you can have a 5, 7, or 9 node cluster too — not in the demo though!). In this webinar, we will cover the steps to do this, with a demonstration of how easy it is for you to do. We will also cover how you may want to load balance traffic to your Galera ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Harshil Shah. The AWS IoT Analytics platform offers configurable dataflows for processing messages from IoT devices, which can be either uni-schema or multi-schema. When you have billions of messages and millions of IoT devices, you need efficient designs for message-processing dataflows.In this post, you do a deep dive into various aspects of designing dataflows. You learn about the types of dataflows, and then look at a simple use case and try to design a dataflow to match its example requirements. Overview This post discusses the following topics: Types of ... Read More

Feed: Blog Post – Corporate – DataStax. Author: Patrick McFadin, VP of Developer Relations. Say what you’ll say about fads or trends, cloud is here to stay, and for many companies “the cloud” has now evolved into “hybrid cloud.” But most organizations didn’t expect to be in hybrid cloud, and now that they’re here their application developers are facing issues they’ve never faced before—issues that require a powerful, flexible, always-on database like Apache Cassandra to resolve.  But before we discuss why Cassandra is such an ideal database for hybrid cloud, we need to understand the how and the why of ...

Feed: Planet MySQL; Author: Severalnines; In the first part of the series, we showed you how to deploy a MySQL Replication setup with ProxySQL with WHM and cPanel. In this part, we are going to show some post-deployment operations for maintenance, management, failover as well as advantages over the standalone setup. MySQL User Management With this integration enabled, MySQL user management will have to be done from WHM or cPanel. Otherwise, ProxySQL mysql_users table would not sync with what is configured for our replication master. Suppose we already created a user called severaln_user1 (the MySQL username is automatically prefixed by ... Read More
