InnoDB is the default storage engine for MariaDB Enterprise Server and MariaDB Community Server. While originally based on the MySQL implementation of InnoDB, MariaDB has been diverging from the original for years in order to give MariaDB users a better experience.
This month, June 2020, IBM introduced a new function level, FL507, for Db2 12 for z/OS. This is the first new function level this year, and the first since October 2019. The Function Level process was designed to release Db2 functionality using Continuous Delivery (CD) in short, quick bursts.
Today I’m going to talk about my favorite trope, “database security”. When done right, a good security policy not only protects your data but improves performance, system stability, and enhances the development life-cycle.
In my recent post Evaluating MongoDB Under Python TPCC 1000W Workload with MongoDB benchmarks, I showed an average throughput for a prolonged period of time (900sec or 1800sec), and the average throughput tended to smooth and hide problems.
Cloud, Cloud, Cloud. Everyone is talking about the Cloud but a lot of people are still in the fog with Cloud technologies. Let’s talk about basic features of the Oracle Cloud, called OCI for Oracle Cloud Infrastructure. OCI is physically a lot of servers in datacenters all around the world.
I’ve heard many times incorrectly over the years that CTEs somehow materialize data. But a new one to me was that CTEs execute procedurally, and you could use that to influence plan shapes by always doing certain things first.
The PostgreSQL Global Development Group announces that the second beta release of PostgreSQL 13 is now available for download. This release contains previews of all features that will be available in the final release of PostgreSQL 13, though some details of the release could change before then.

As the name indicates, an undo log record contains information about how to undo the recent changes by a transaction. When a transaction writes data, it always makes writes on the tablespace files. InnoDB Undo log stores copy of data that is being modified by any current transaction.
To continue the series, this PowerShell monitoring script will collect instance level data for all of SQL Servers that have been registered for this monitoring solution. This module will gather information about the SQL Server instance, such as the version, edition, memory settings and more.
Aspen Mesh sponsored this post. One of the bright points to emerge in Kubernetes management is how the core capabilities of the Istio service mesh can help make engineering teams more efficient in running multicluster applications.
An important part of performing a migration from Oracle to PostgreSQL is selecting the right tool for helping with the conversion between systems. When people ask me how they can get the migration process started, I like to recommend a powerful open source utility called "ora2pg".
Usually, database people are familiar with table fragmentation with DELETE statements. Whenever doing a huge delete, in most cases, they are always rebuilding the table to reclaim the disk space. But, are you thinking only DELETEs can cause table fragmentation? (Answer: NO).
You should never take any decision on what you read on the internet without verifying. It is totally valid to consider a move to Open Source databases, but doing it without good understanding is a risk for your migration project success.
Turning raw data into improved business performance is a multilayered problem, but it doesn’t have to be complicated. To make things simpler, let’s start at the end and work backwards. Ultimately, the goal is to make better decisions during the execution of a business process.
Have you always wanted to paint pictures with your data? Do you strive to accelerate your data science cycles and rapidly iterate by running your analytics on GPUs? Or do you just like Spark and want to work with your favorite MLlib algorithms? Lucky for you, we have each of these bases covered in t
