We usually take care of things we value, whether it is an expensive smartphone or the company’s servers. Data is one of the most important assets of the organisation, and although we do not see it, it has to be carefully protected. We implement data at rest encryption to encrypt database files or whole volumes which contain our data. We implement data in transit encryption using SSL to make sure no one can sniff and collect data sent across networks. Backups are no different. No matter if this is a full backup or incremental, it will store at least a part of your data. As such, backups have to be encrypted too. In this blog post, we will look into some options you may have when it comes to encrypting backups. First though, let’s look at how you can encrypt your backups and what could be use cases for those methods.

How to encrypt your backup?

Encrypt local file

First of all, you can easily encrypt existing files. …

During our recent migration we migrated a part of a app to different region with new db. Our previous setup was on MySQL 5.6.39 with single write master and multiple slave to read data.  
Current Setup:


But now Masters will be two one for old and second for new migrated service. We moved new master on MySQL 5.7 with GTID, MTS and Logical Clock based replication. So our use case was to read whole data (written on master1 + master2) from slaves.

So now question is What we have done to achieve this?

Below is New Setup:

Today I read the nice post of Bhuvanesh on the memory leak issue they experienced with MySQL. In fact when you read the post, you realize that MySQL was just following the parameters that were setup (the default of max_prepare_stmt_count is 16382 even on 5.6).

I’m still convinced that the problem should be resolved in the application even if the use of ProxySQL for multiplexing is great.

In MySQL 8.0, we have enabled the …

I am currently working my way through the many PHP Frameworks to see how they get on with MySQL 8.  The Frameworks that can take advantage of the MySQL Improved Extension or mysqli can take advantage of the SHA256 Caching Authentication method. But those that are PDO based need to use the older MySQL Native Authentication method.

I wanted to check the PDO based frameworks and today I just happened to be wearing the very nice Symfony shirt I received as part of my presentation at Symfony USA.  So I started with a fresh install of Symfony.  All was going well until it came time to get it to work with MySQL 8 through Doctrine.

Doctrine
Symfony uses Doctrine as an ORM (Object Relational Mapper) and DBAL  (Database Abstraction Layer) as an intermediary to the database.  While I myself am not a big fan of ORMs …

In this Checklist for Success series, we will discuss reducing unknowns when hosting in the cloud using and migrating to Amazon Aurora. These tips might also apply to other database as a service (DBaaS) offerings.

Previous blogs in the migrating to Amazon Aurora series:

• Migrating to Amazon Aurora: Reduce the Unknowns
• Migrating to Amazon Aurora: Optimize for Binary Log Replication

The whole premise of a database as a service offering is that you do not need to worry about the operating the …

Design A Highly Available MySQL Clusters With Orchestrator And ProxySQL In GCP — Part 2

In part1, we explained how we are going to approach the HA setup. Here we can see how to install and configure Orchestrator and ProxySQL, then do the failover testing.

Install and configure MySQL Replication:

We need a MySQL with 4 Read replica and the 4'th replica will have a replica for it. And we must have to use GTID replication. Because once the master failover done, the remaining replicas will start replicating from the new master. Without GTID its not possible, but as an alternate Orchestrator provides Pseudo-GTID.

VM Details: …

Design A Highly Available MySQL Clusters With Orchestrator And ProxySQL In GCP — Part 1

Recently we have migrated one of our customer's infra to GCP and post the migration we published some adventures on ProxySQL which we implemented for them.

1. Reduce MySQL Memory Utilization With ProxySQL Multiplexing
2. How max_prepared_stmt_count can bring down production

Now, we are going to implement an HA solution with customer filter for failover. We have done a PoC and the blog is about this PoC configurations. And again the whole setup has been implemented in GCP. You can follow the same steps for AWS …
