The database conference organization I’ve focused on for most of my career – IDUG (International Db2 Users Group) is not interested in cross-platform content. Despite being a top speaker most conferences, they are not interested in content from me that covers things like transitioning from Db2 to MySQL or technical writing about database concepts.… Read the restContinue reading »
I’m a couple of months into working with MySQL, and thought I’d share some resources and thoughts on what I’m learning and what is working. At least half of that time was dedicated to a very in-depth onboarding process that barely mentioned a database at all in about a month of content, so it’s closer to a month in.… Read the restContinue reading »
Many RDBMSes have similar structures and concepts. In this post, I’m going to compare and contrast IBM Db2’s concept of a clustered index and MySQL’s concept of a clustered index.
Index vs. Clustered Index
An index is generally a way of organizing data in a way that it will be quicker to access than scanning through all of a table.… Read the restContinue reading »
I’ve struggled to write this blog entry to appropriately convey all aspects of what I want to say. This is my third attempt, and I finally think it does things justice.
As part of my publicly shared data science journey, I’ve continued to read job postings, even while reasonably satisfied with my current job.… Read the restContinue reading »
Db2u is here as a technical preview! I’ll cover the basics of how to set it up for a local sandbox, and leave the details and whys to future articles. IBM has stated that db2u will be available in GA later this year on Amazon EKS and Azure EKS, but meanwhile, I’ve got the technical preview up and running on my MacBook Pro!… Read the restContinue reading »
Earlier in 2021, I wrote an article on the big mistake I thought IBM was making by only offering their container-native version of Db2 (db2u) on RedHat OpenShift.
Well, that article and tirelessly asking questions of EVERY IBMer I could get to listen to me (seriously, I could hear eyes rolling when I asked for the umpteenth time) has finally worked!… Read the restContinue reading »

This year, I’m going to be working through the Advent of Code challenges in SQL and sharing my progress here on the blog. I don’t expect to complete each challenge and the blog entries on them on the same day they are released – I’m not competing on time, I’m just using this to share SQL techniques.… Read the restContinue reading »
What is a Buffer Pool?
A buffer pool is one of the most critical memory areas for a Db2 database. Buffer pools are used to cache data in a way that the data can be reused by other connections. They do not store the results of Query A and Query B, but they store the data pages used to produce those results.… Read the restContinue reading »
