MySQL 8.0 became Generally Available (GA) on April 19th, a great moment for us working on MySQL at Oracle. It is now a “fully grown adult” packed with new features, and improvements to existing features, as described here.
This blog post focuses on the impact of replication performance improvements that went into MySQL 8.0.…
MySQL 8.0.1 introduces new features and improvements to replication. The next sections summarize some related to performance.
1. WL#9556 – Writeset-based dependency tracking on the master
Transaction writesets can now be used to evaluate which transactions are independent and can be executed in parallel on the binary log applier on the asynchronous slaves.…
MySQL 8.0.1 introduces a new mechanism to track the dependencies between transactions. This feature is used to optimize the binary log applier on asynchronous replication slaves, improving the throughput significantly on workloads where there is low-concurrency on the master and/or on systems with very fast storage.…
Great news: Group Replication is now officially released with MySQL 5.7.17, congratulations to everybody that worked so hard for it!
In this post I plan to share more details about the performance of Group Replication while addressing one of our frequently asked questions, which is how it performs compared to Galera.…
A previous blog post exposed the main factors affecting Group Replication performance, which was followed by another that showed the scalability of both single-master and multi-master throughput. In this post we return with more “inside information” that may be useful for optimizing the performance of Group Replication deployments.…
In this blog post we will present a first look at the performance of Group Replication (GR), now that the RC is out. The goal is to provide some insight on the throughput, latency and scalability one can expect in a modern computing infrastructure, using GR in single- and multi-master configurations, but mostly focused on single-master.…
Group Replication introduces a new way to do replication in MySQL. With great features such as multi-master replication it brings a range of exciting deployment scenarios where some difficult problems become much easier to solve. Group Replication also brings a new set of options that may need to be configured to extract the highest performance from the underlying computing resources.…
The MySQL family has grown with the introduction of the Router, which brings high-availability and Fabric integration to all MySQL clients independently of any specific connector support for them. This blog focuses on the throughput of the Connection Routing plugin for Router and evaluates the overhead it may bring to application performance compared to direct connection.…
With MySQL 5.7 becoming GA it’s a good time to highlight how much performance has improved in replication since the 5.6 era. A previous blog post focused on the performance of the multi-threaded slave applier and on this one the target is the semi-synchronous replication plug-in (SemiSYNC), whose performance has improved greatly.…
Now that MySQL 5.7 has become GA it’s a good time to highlight how much performance has improved in replication since the 5.6 era. This blog post will focus on the performance of the multi-threaded slave applier (MTS), and about it’s scalability in particular.…
