High availability read-write splitting with php-mysqlnd, MySQL Replication and HAProxy
+0 Vote Up -0Vote Down

MySQL Replication is used in a variety of use cases - scale out read workloads, provide high availability and geographic redundancy, offload backups and reporting/analytic jobs. However it has a big drawback - the application needs to be able to send writes to the master only. Updating more than one master in a replication setup can result in data inconsistency and cause replication to break.

An SQL-aware load balancer like …

+0 Vote Up -0Vote Down

MariaDB won the 2013 and the 2014 LinuxQuestions.org Members Choice Award Database of the Year, and is in the running again for 2015 winner. Up until 2012, MySQL held a near-monopoly on the title, having won every year since at least 2001 (except for 2002, won by PostgreSQL). Since 2013, however, it’s been all MariaDB, […]

Fun with Bugs #41 - Bugs Fixed in MySQL 5.7.11
+0 Vote Up -0Vote Down

I've just noted that Oracle had released new versions of MySQL on February 5, 2016 formally, so while these days I am mostly thinking about the ways to do support properly, remembering my colleagues and trying to understand some of RocksDB internals, it's time to postpone all these and write about bugs again. This time about some of the public bug reports from MySQL Community and Oracle engineers that were fixed by Oracle in MySQL 5.7.11.

As usual, I'll try to mention who had reported a bug and who verified it, as I think that names …

Finding and deleting orphaned rows in MySQL
+0 Vote Up -0Vote Down

If you store data with a parent-child relationship in MySQL tables, then you may want to identify and/or delete orphaned rows from the child table. An orphaned row is defined as a child row that references a non-existant parent row. If you enforce the parent-child relationship with a foreign key constraint on the child table then orphans are less likely to occur, but you can still end up with orphans; for example if a user disables foreign_key_checks in a session and deletes a parent row. If you choose not to create foreign keys in your database in order to avoid the performance overhead, then you are at higher risk of having …

Measuring Percona Server Docker CPU/network overhead
+0 Vote Up -0Vote Down

Now that we have our Percona Server Docker images, I wanted to measure the performance overhead when we run the database in the container. Since Docker promises to use a lightweight container, in theory there should be very light overhead. We need to verify that claim, however. In this post I will show the numbers for CPU and network intensive workloads, and later I will take a look …

MySQL Community Awards 2016: Call for Nominations!
+1 Vote Up -0Vote Down

The 2016 MySQL Community Awards event will take place, as usual, in Santa Clara, during the Percona Live Data Performance Conference, April 2016.

The MySQL Community Awards is a community based initiative. The idea is to publicly recognize contributors to the MySQL ecosystem. The entire process of discussing, voting and awarding is controlled by an independent group of community members, typically based of past winners or their representatives, as well as known contributors.

It is a self-appointed, self-declared, self-making-up-the-rules-as-it-goes committee. It is also very aware of the importance of …

MariaDB JIRA is moving
+0 Vote Up -0Vote Down

The MariaDB JIRA instance that currently is in use for project and issue tracking will change. The current instance is hosted in Atlassian’s cloud and it has worked well, but we have hit the maximum user limit of 2000 users. It’s fantastic to see how many of you actually report bugs and other issues in the MariaDB […]

MySQL Connector/Python currently not available from PyPI
Employee +1 Vote Up -0Vote Down

With PEP 470 now requiring files to be hosted on PyPI, you may have noticed that MySQL Connector/Python is now no longer available using the pip-tool.

The MySQL Engineering team at Oracle really would like to have the connector available through PyPI and have been talking with the Python Foundation towards that. We know users and developers of OpenStack, for example, have requested this as well as lots of other Python users.

For now …
