MySQL Master Replication Crash Safety Part #5a: making things faster without reducing durability - using better hardware

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

MySQL Master Replication Crash Safety Part #5: faster without reducing durability (under the hood)

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,

MySQL Master Replication Crash Safety Part #4: benchmarks of high and low durability

This is a follow-up post in the MySQL Master Replication Crash Safety series.  In the three previous posts, we explored the consequence of reducing durability on masters (including setting sync_binlog to a value different from 1).  But so far, I only quickly presented why a DBA would run MySQL with such configuration.  In this post, I present actual benchmark results.  I also present a

On the Database Market. Interview with Merv Adrian

“Anyone who expects to have some of their work in the cloud (e.g. just about everyone) will want to consider the offerings of the cloud platform provider in any shortlist they put together for new projects. These vendors have the resources to challenge anyone already in the market.”– Merv Adrian.

I have interviewed Merv Adrian, Research VP, Data & Analytics at Gartner. We talked about the the database market, the Cloud and the 2018 Gartner Magic Quadrant for Operational Database Management Systems.

Q1. Looking Back at 2018, how has the database market changed?

Merv Adrian: At a high level, much is similar to the prior year. The DBMS market returned to double digit growth in 2017 (12.7% year over year in Gartner’s estimate) to $38.8 …

How to Enable Binary Logging on an Amazon RDS Read Replica

One of the more common struggles I’ve had to assist with in regard to Amazon RDS is enabling binary logging on read replicas, or forming multi-tier replication in instances using version 5.6 or later after seeing that multi-tier replication is not supported in version 5.5 (for a reason that will become clear by the end of this post.)

First off, let’s have a look at the topology that I have in place in my AWS account. As you’ll see below I have a master, blog1, and a read replica that I created via the AWS console called blog2. You’ll also notice that, despite being supported, if I select instance actions while having blog2 highlighted the option to create a read replica is grayed out.

Further, if we use the MySQL CLI to connect to blog2 and check the global variables for log_bin and binlog_format, you’ll see that binary logging is off and binlog_format is set to statement. This is strange considering that the parameter …

Top 5 Reasons to Move MySQL to AWS EC2

Many organizations are shifting toward the cloud, but how much are they moving over? New post explains top five reasons to move your MySQL database to AWS EC2.

Monitoring Amazon RDS: Beyond Raw Logs

Amazon Relational Database Service (RDS) is a hosted database service in the AWS cloud. If your organization’s data is stored in one of the popular database systems, but on a company server or perhaps you’re renting a dedicated server, you might want to consider switching to Amazon RDS.  With Amazon RDS, you can choose from several relational database systems:  MySQL, MariaDB, Oracle, Postgres, and SQL Server, as well as Amazon Aurora.

There are many advantages to Amazon RDS, such as server scaling and load balancing of user traffic. Best of all, it can reduce the operational costs of running database software like MySQL. With Amazon RDS, you don’t need to worry about performing security updates, patching the operating system, or tuning the database. In fact, some of the patches Amazon deploys for MySQL and MariaDB are specifically designed to get better performance in a cloud setting.  Let’s look at some major …

Amazon RDS updates February 2016

I think one of the big announcements that came out from the Amazon Web Services world in October 2015 was the fact that you could spin up instances of MariaDB Server on it. You would get MariaDB Server 10.0.17. As of this writing, you are still getting that (the MySQL shipping then was 5.6.23, and today you can create a 5.6.27 instance, but there were no .24/.25/.26 releases). I’m hoping that there’s active work going on to make MariaDB Server 10.1 available ASAP on the platform.

Just last week you would have noticed that Amazon has rolled out MySQL 5.7.10. The in-place upgrades are not available yet, so updating …

3 Big Announcements from MariaDB (my take for Oct 2015)

Today I received about five emails with the subject: 3 Big Announcements from MariaDB. Maybe you did as well (else, read it online). October has brought on some very interest announcements, and I think my priority for the big announcements vary a little:

  1. MariaDB Server is now available on Amazon RDS – you wouldn’t believe how many people ask for this, as many now deploy using Amazon …
