+2 Vote Up -1Vote Down

You see, Monty has fundamentally crafted a straw man to stand in for the general Open Source model by applying his experience in the dog-eat-dog world of forked software, in particular, the "ecosystem" of MySQL.  The software that MariaDB draws the majority of their income from is MariaDB, which is a fork of MySQL.  If you don't know the history, well, you see, SUN bought MySQL, Oracle bought Sun, and Monty, in an environment of nearly Biblical levels of FUD, forked MySQL into MariaDB (both products are …

Employee_Team +1 Vote Up -0Vote Down

I worked on an issue last recently where a query was too slow when executed in MySQL Cluster. The issue was that Cluster has some restrictions when it comes to push down conditions.

As an example of this, consider the following query using the employees sample database. The query takes a look at the average salary based on how many years the employee has been with the company. As the latest hire date in the database is in January 2000, the query uses 1 February 2000 as the reference date.

Initially the query performs like (performance is with two data nodes and all nodes in the same virtual machine on a laptop, so the timings are not …

On Using HPE Vertica. Interview with Eva Donaldson.
+0 Vote Up -0Vote Down

“After you have built out your data lake, use it. Ask it questions. You will begin to see patterns where you want to dig deeper. The Hadoop ecosystem doesn’t allow for that digging and not at a speed that is customer facing. For that, you need some sort of analytical database.”– Eva Donaldson.

Linux User-Group Console
+0 Vote Up -0Vote Down

This post shows you how to add the menu option and GUI to set users and groups. It’s quite a bit easier than mastering all the command-line syntax. It makes setting up the required user and group accounts for an Oracle Enterprise or MySQL database solution much easier.

You add the utility by calling the yum (Yellowdog Updater, Modified) utility like this:

yum installed -y system-config_users

You should see the following:
