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.…
Starting on MySQL 8.0.1, a very updated replica server will be more efficient (and probably faster) than previous MySQL versions because of improvements in the relationship between the replication threads. Preliminary testing showed a benefit of up to 65% on Sysbench Update Index.…
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.…
In this tutorial, we are going to guide you through the entire process of creating a 3 node InnoDB cluster in Oracle Public Cloud (OPC). We will address each of the steps, from the initial configuration and setup of the OPC IaaS resources to the InnoDB cluster creation and setup.…
Yes, another post about my talks at Percona Live Santa Clara: I obviously still have things to share. This time, I will focus on my parallel replication talks by giving a short preview.
I have two parallel replication talks at Percona Live:
MySQL/MariaDB Parallel Replication: inventory, use cases and limitations (Wednesday talk) MySQL Parallel Replication: all the 5.7 (and some of the 8.0)
The new release of MySQL is packed with exciting features that help detecting and analyzing replication lag. In this post, you will be able to learn all about the new replication timestamps, the new useful information that is now reported by performance schema tables, and how delayed replication was improved.…
In a previous post, I listed all the Booking.com talks at Percona Live. In this post, I will give more details about my talks.
As a reminder, the list of my talks is the following:
Monitoring Booking.com without looking at MySQL (Thursday keynote) The two little bugs that almost brought down Booking.com (Tuesday Lightning Talk) MySQL/MariaDB Parallel Replication: inventory, use cases and
In a week, me and some Booking.com colleagues will be in Santa Clara for Percona Live.
Booking.com is sponsoring the conference and we will be present at the Monday Evening Reception. You do not need a tutorial pass to attend the dinner (even if it is on the tutorial day): any valid pass will do. If you do not have your ticket yet, it is time to register (you can use the discount code “
TokuDB Hotbackup is a solution that allows you to do backups on the fly. It works as a library that intercepts certain system calls that duplicate data written to already copied parts of files, so that at the end of the backup process the copied files contain the same content as the original files. There are several blog posts describing how TokuDB Hot Backup works in details:
[Read more]In this blog we are going to view about a new feature in latest release MySQL 8.0.1 for MySQL Replication . It is binlog_expire_logs_seconds.
Previously we can set the expire logs for binlogs in number of days. By using the new feature (binlog_expire_logs_seconds) we can see set the expire time into number of seconds.
The both expire_logs_days and binlog_expire_logs_seconds works when the binlog rotate happens in the server.
The ultimate usage of this feature will be used to set expire periods smaller than a day by providing another extra variable.
The new variable binlog_expire_logs_seconds, can be used in those cases where the expire period is not an integral …
