Feed: Planet MySQL; Author: Kristian Köhntopp; Like I said, I never had much reason to use table compression, and only recently looked into the topic. MySQL Page Compression looks a lot easier at the database end of things, but relies on hole punching support in the file system. Let’s have a look at what that means. The original Unix filesystem saw the disk as a sea of blocks, which were represented in a free map as an array of bits. Files have numbers, which are an index into an array of so-called inode structures. Inodes store the files metadata and ... Read More

Feed: What's New. Author: Forbes BrandVoice. Editor's note: This article originally appeared in Forbes. Before we get started, why do I even need one? It’s now rare to find an executive who doesn't want their organization to be more data driven. Becoming a data-leading company requires not only data and analytics but also a data culture—a way of working that puts data at the heart of every decision. In companies with a data culture, everyone, regardless of their role, can find insights to improve the business. At many organizations, these cultures begin to take root upon the formation of a ...

Feed: Planet PostgreSQL. In part 1 of this blog mini-series we looked at how to setup PostgreSQL so that we can perform regression analysis on our data using TensorFlow from within the database server using the pl/python3 procedural language. In part 2 we looked at how to understand and pre-process the data prior to training a neural network. In this third and find part, we'll use the data that we've prepared and optimised to train a network and then use it to analyse data - all from within a PostgreSQL database!  Splitting the Data When we finished the last part of ...

Feed: Alation. Author: Jason Lim. Alation, business glossary, data catalog, data dictionary, enterprise data catalog April 26, 2021 — In your organization, are you ever confused by different definitions of business terms? Do you ever wonder why the number of customers differs between two reports? I’m going to assume the answer is “yes.” And you are not alone. As an organization evolves, it’s natural for the language to evolve, too. That’s why it’s critical that important terms be defined, documented, and made visible to everyone. This aligns understanding, so that, for example, a term like “customer” means the same thing ... Read More

Feed: Planet PostgreSQL. In part 1 of this blog mini-series on machine learning, we looked at how to setup PostgreSQL so that we can perform regression analysis on our data using TensorFlow from within the database server using the pl/python3 procedural language. We also looked at some of the basics of pl/python3 as a primer for what is to come in this and part 3 of the series.In this part, we'll look into data pre-processing. In order to ensure that our regression analysis is as accurate as possible, we first need to analyse and understand the raw data. We can use ... Read More

Feed: Planet MySQL; Author: Marcelo Altmann; Chasing bugs can be a tedious task, and multi-threaded software doesn’t make it any easier. Threads will be scheduled at different times, instructions will not have deterministic results, and in order for one to reproduce a particular issue, it might require the exact same threads, doing the exact same work, at the exact same time. As you can imagine, this is not straightforward. Let’s say your database is crashing or even having a transient stall.  By the time you get to it, the crash has happened and you are stuck restoring service quickly and ... Read More
