Oracle’s “Always Free” Cloud Instance – Adding a web server to your free MySQL compute instance with zero monthly charges

In a previous post, I explained how you can take advantage of Oracle’s “Always Free” Cloud instance to obtain a free Oracle Cloud compute instance (virtual machine) and install a copy of MySQL – without having to pay a setup fee and without incurring any monthly charges. And, you can have two free compute instances per account.

This free Cloud option from Oracle is great. I can think of a lot of ways to utilize a free Oracle Cloud compute instance – but the first one that came to …

The Slow Software Movement

Those who build SaaS know that you’re actually providing an experience. You’re building long-term relationships and aiming for recurring revenue. Therefore, your product must be flexible, resilient, and consistent.

Many companies find it hard to take time, acquire the right ingredients, and design truly great software from the bottom-up. This is understandable given how fast the SaaS industry moves.

But firstly, who am I to be talking about this subject? My education was in Economics and Complex Systems, and I’ve been fortunate to gain exposure to various IT trends and tools working almost a decade mostly in Tech. I started interviewing customers at Continuent (majority SaaS) over five years ago, and I have listened to a number of …

MySQL introduced a JSON data type in version 5.7, and expanded the functionality in version 8.0.

Besides being able to store native JSON in MySQL, you can also use MySQL as a document store (doc store) to store JSON documents. And, you can use NoSQL CRUD (create, read, update and …

NoSQL + SQL = MySQL 8; Keynote OSI2019

NoSQL + SQL = Mysql 8 Open Source India 2019 keynote from Sanjay Manwani

Slides from the keynote presented at Open Source India 2019 at Nimhans convention center Bangalore. As usual lots of interesting folks. Lots of focus on Open Source.

Met people from the SODA foundation who are trying to standardize the IO layer across all cloud implementations. All the best guys.

Also met folks from MOSIP who have an effort ongoing to help countries create their own UID. Seems like they already have some traction.

Also met an interesting person trying to think about Indian design and creativity in software. After Chumbak it does make sense to think about how not only UI but the software development …

How free is your Open Source software…really?

With growing development and support costs as well as the need to maintain a sustainable business, it became apparent that maintaining the OSS release of Tungsten Replicator (TR) just wasn’t viable. Earlier this year we decided to close it down, instead focusing our efforts on improving and developing its commercial release whilst also growing our flagship commercial product, Tungsten Clustering.

For many businesses, Open Source Software (OSS) is still a very viable solution in many use cases, and I’m sure it will continue to be so for a long time, but I wanted to explore whether an OSS solution really is as free as the $0 price tag suggests.  In this blog I explore just that..

The hidden costs of OSS

Over the last few weeks I stumbled …

Save Space on MySQL data with Column Compression

                                   Recently, One of our client reached our Remote DBA team with a requirement to reduce the size of the table as it is having many text columns with huge number of records. At preliminary check , I have validated the table size and its row format, as it was  in compressed  format already. 

Later I checked on other possibilities to compress the text columns further, At that time, then I came across per-column compression feature in Percona MySQL server (From 5.7.17-11) which features individual column compression and we were using …

Session Variables

In MySQL and Oracle, you set a session variable quite differently. That means you should expect there differences between setting a session variable in Postgres. This blog post lets you see how to set them in all three databases. I’m always curious what people think but I’m willing to bet that MySQL is the simplest approach. Postgres is a bit more complex because you must use a function call, but Oracle is the most complex.

The difference between MySQL and Postgres is an “@” symbol versus a current_setting() function call. Oracle is more complex because it involves the mechanics in Oracle’s sqlplus shell, SQL dialect, and PL/SQL language (required to assign a value to a variable).

MySQL

MySQL lets you declare a session variable in one step and use it one way in a SQL statement or stored procedure.

  1. You set a session variable on a single line with the following …

MySQL Check Constraints to the Rescue

   

You as a MySQL administrator/developer are really excited about cloning in MySQL 8.0.17.  You are reading all the recent blogs. You know that quickly getting a replica up and running is quite important to your dev team.

Besides, ‘cloning’ reminds you of the old classic film ‘Sleeper’ where the actors clone a new leader from the dead leader’s nose. 

Thinking of all this puts you in great spirits. Moving from MySQL 5.7 to MySQL 8.0 is high on your agenda. 

Suddenly, the CEO walks up to your desk. “We lost millions in sales last quarter,” he yells. “It’s your fault. We sold all of our items at the discounted price rather than the actual price. You need to fix this today if not sooner.” 

With that, the CEO reminds you of another reason to move to MySQL 8.0 : check constraints, which came out in 8.0.16. 

You know that ensuring that data is …
