Feed: Planet MySQL; Author: Severalnines; RDS is a Database as a Service (DBaaS) that automatically configures and maintains your databases in the AWS cloud. The user has limited power over specific configurations in comparison to running MySQL directly on Elastic Compute Cloud (EC2). But RDS is a convenient service, as long as you can live with the instances and configurations that it offers. Amazon RDS currently supports various MySQL and MariaDB versions as well as the, MySQL-compatible Amazon Aurora DB engine. It does support replication, but as you may expect from a predefined web console, there are some limitations. Amazon ... Read More

Feed: Planet MySQL; Author: Yelp Engineering; Since its inception in 2013, Yelp has grown its transactions platform to tens of millions of orders. With this growth, it’s become slow and cumbersome to rely solely on MySQL for searching and retrieving user orders. Transactions at Yelp are built around integrations with dozens of external fulfillment partners across different verticals, from food ordering to spa reservations. In most of these integrations, Yelp takes care of payment processing. Given this, the way we store order details prioritizes facilitating stateful order processing in a uniform way. However, other access patterns like finding popular orders ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; Dov Endress | May 16, 2018 |  Posted In: Insight for DBAs, Insight for Developers, MySQL, Percona Server for MySQL PREVIOUS POST MySQL, coupled with the InnoDB engine, provides full ACID compliance. With the addition of “eXtended Architecture” (XA) technology, they can all act in a distributed atomic environment. In distributed systems, several different technologies, platforms and devices may need to act on separate sets of data atomically. These backend datasets can exist side by side in a datacenter, or across oceans. There can be multiple datasets where atomicity is a necessity. Foreign engines could completely ... Read More

Feed: Planet MySQL; Author: MySQL High Availability; In the Replication QA team, we have been continuing to improve test coverage for Replication and Group Replication primarily to ensure that we support the newest and latest offerings of MySQL Server 8.0 such as Generated Columns, Set Persist, User Roles, and User Management DDLs that are now atomic. As a rule, we include tests for both MySQL Replication (master/slave, asynchronous replication) and Group Replication (group membership) topologies to ensure everything works out of the box with defaults. In this blog, we discuss several additions to the MySQL QA testing suite (MTR). These ... Read More

Feed: Planet MySQL; Author: Severalnines; In the past four posts of the blog series, we covered deployment of clustering/replication (MySQL/Galera, MySQL Replication, MongoDB & PostgreSQL), management & monitoring of your existing databases and clusters, performance monitoring and health and in the last post, how to make your setup highly available through HAProxy and ProxySQL. So now that you have your databases up and running and highly available, how do you ensure that you have backups of your data? You can use backups for multiple things: disaster recovery, to provide production data to test against development or even to provision a ... Read More

Feed: Planet MySQL; Author: Andrew Grimo; There are lots of new features in MySQL 8.0 that was recently released including our Document Store capability.  There are a few core capabilities related to InnoDB Cluster in 8.0 that I’d like to share but some will arrive in some coming blogs.  Primarily here I’ll point out some nice details with InnoDB Cluster 8.0 deployments, plus point out how our ability to SET PERSIST GLOBAL configurations allows us to see the beneficial impact of the new replication default configurations in 8.0. I use a set of scripts to build and rebuild my clustered test setups ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; Vadim Tkachenko | May 4, 2018 |  Posted In: Benchmarks, Insight for DBAs, MySQL, MySQL 8.0 PREVIOUS POST As part of my benchmarks of binary logs, I’ve decided to check how the recently released MySQL 8.0 performance is affected in similar scenarios, especially as binary logs are enabled by default. It is also interesting to check how MySQL 8.0 performs against the claimed performance improvements in redo logs subsystem. I will use a similar setup as in my last blog with MySQL 8.0, using the utf8mb4 charset. I have a few words about MySQL 8.0 tuning. Dimitri’s ... Read More

Feed: Planet MySQL; Author: MySQL Performance Blog; Vadim Tkachenko | May 4, 2018 |  Posted In: Benchmarks, InnoDB, Insight for DBAs, MySQL, MySQL 8.0 PREVIOUS POST I want to take a closer look at MySQL performance with binary logs enabled on different filesystems, especially as MySQL 8.0 comes with binary logs enabled by default. As part of my benchmarks of the MyRocks storage engine, I’ve noticed an unusual variance in throughput for the InnoDB storage engine, even though we spent a lot of time making it as stable as possible in Percona Server for MySQL. In the end, the culprit was enabled binary ... Read More
