Pythian at DataOps Barcelona

DataOps Barcelona is an event organized by Binlogic and will be taking place June 21-22, 2018 in Barcelona, Spain. Pythian is proud to be supporting this inaugural open source-focused conference in Europe!

DataOps is of course short for “Database + Operations” and contains talks about the various open-source database ecosystems and how they are operationalized with regards to cloud solutions, security, automation, high availability and scaling.

Pythian has a long history of helping companies leverage open source technologies and cloud infrastructure to meet their business requirements. We excel at managing traditional open source relational database (MySQL) and relatively new NoSQL technologies (MongoDB, Cassandra).

Building the PHP MySQL XDevAPI PECL Extension on MySQL 8.0.11 and PHP 7.2 for the MySQL Document Store

The MySQL Document Store is a NoSQL JSON document store built upon well known MySQL database technology.  PHP runs about eight percent of the Internet.  So putting the two together is a big priority for me. So this blog post is about getting all this together on a Ubuntu 18.04 system.

Note that I will be teaching PHP and the X DevAPI at Oracle Code One and hopefully in some tutorials/workshops this year.  These session will feature the X DevAPI installed on Virtual Box images and I probably will not have time to cover these steps in detail but I will point to this as reference material.


PHP 7.2 PHP's performance has really skyrocketed with the seven series and the newer betas are looking very impressive.  But to use the new X Devapi you will need to get the shared object for it into your PHP server.

The connection_control plugin : Keeping brute force attack in check

To quote book of all knowledge:

In cryptography, a brute-force attack consists of an attacker trying many
passwords or passphrases with the hope of eventually guessing correctly.
The attacker systematically checks all possible passwords and passphrases
until the correct one is found.

Is Serverless Just a New Word for Cloud-Based?

Serverless is a new buzzword in the database industry. Even though it gets tossed around often, there is some confusion about what it really means and how it really works. Serverless architectures rely on third-party Backend as a Service (BaaS) services. They can also include custom code that is run in managed, ephemeral containers on a Functions as a Service (FaaS) platform. In comparison to traditional Platform as a Service (PaaS) server architecture, where you pay a predetermined sum for your instances, serverless applications benefit from reduced costs of operations and lower complexity. They are also considered to be more agile, allowing for reduced engineering efforts.

In reality, there are still servers in a serverless architecture: they are just being used, managed, and maintained outside of the application. But isn’t that a lot like what cloud providers, such as Amazon RDS, Google Cloud, and Microsoft Azure, are already …

Chunk Change: InnoDB Buffer Pool Resizing

Since MySQL 5.7.5, we have been able to resize dynamically the InnoDB Buffer Pool. This new feature also introduced a new variable — innodb_buffer_pool_chunk_size — which defines the chunk size by which the buffer pool is enlarged or reduced. This variable is not dynamic and if it is incorrectly configured, could lead to undesired situations.

Let’s see first how innodb_buffer_pool_size , innodb_buffer_pool_instances  and innodb_buffer_pool_chunk_size interact:

The buffer pool can hold several instances and each instance is divided into chunks. There is some information that we need to take into account: the number of instances can go from 1 to 64 and the total amount of chunks should not exceed 1000.

So, for a server with 3GB RAM, a buffer pool of 2GB with 8 instances and chunks at default value (128MB) we are going to get 2 chunks per instance:

This means that there will be 16 chunks.

Using MySQL Shell 8.0.11 “upgrade checker” to upgrade from MySQL 5.7 to MySQL 8.0 successfully

We are really excited about MySQL 8.0 new features (https://dev.mysql.com/doc/refman/8.0/en/mysql-nutshell.html) and our consultants spend several hours weekly, testing new features and doing research on how best we can create value for our customers from having those in production. Being an pure-play MySQL consulting, support and remote DBA services company, We are fully accountable for our customer database infrastructure operations performance, scalability, high availability and reliability.  As we are aggressive about gaining maximum results from MySQL 8 investments made by our customers, We are equally conservative (our customer data reliability is critical for us !)  on adopting new features, until we are fully confident after several rounds of testing (at different scales on multiple platforms) and technical review (we engage both internal and …
