The Small Data Showdown in Microsoft Fabric

Published 2025-07-01 by Kevin Feasel

Miles Cole does a bit of testing:

First, let’s revisit the purpose of the benchmark: The objective is to explore data engineering engines available in Fabric to understand whether Spark with vectorized execution (the Native Execution Engine) should be considered in small data architectures.

Beyond refreshing the benchmark to see if any core findings have changed, I do want to expand in a few areas where I got great feedback from the community:

I really appreciate the approach behind this, both in terms of sticking to more realistic data sizes for many operations as well as performing this test given all of the recent improvements in each engine.

Enumerating Template Types in Power BI

Published 2025-07-01 by Kevin Feasel

Oscar Martinez lays out the list:

A Power BI Template can mean very different things depending on who you ask. Are we talking about a .PBIT shell, a JSON theme, a turnkey Template App, or merely a thin report wired to a central model?

In this post, we cut through the ambiguity and lay each option side‑by‑side. You’ll learn what’s inside every “template” type and the trade‑offs that matter in real‑world projects—so the next time someone says “just use a template” you’ll know exactly which one fits the bill.

Using Barman to Back Up HA-Enabled PostgreSQL Clusters

Published 2025-07-01 by Kevin Feasel

Semab Tariq reminds us that high availability is not disaster recovery:

Barman is a popular tool in the PostgreSQL ecosystem for managing backups, especially in High Availability (HA) environments. It’s known for being easy to set up and for offering multiple types and modes of backups. However, this flexibility can also be a bit overwhelming at first. That’s why I’m writing this blog to break down each backup option in a simple and clear way, so you can choose the one that best fits your business needs.

Why Not Use VARCHAR(MAX) for Everything?

Published 2025-07-01 by Kevin Feasel

David Fowler explains:

When I mentioned to the developer that it’s probably not the best idea, he turned around and asked me, ‘why not?’

It was a genuine question. Why shouldn’t we just spam VARCHAR(MAX) over all of our columns? On the upside, it would get rid of all those annoying issues that crop up when we try to insert a value that overflows the datatype.

Performance Testing the pg_tde Extension

Published 2025-07-01 by Kevin Feasel

Transparent data encryption is now available in PostgreSQL and Andreas Scherbaum has some performance measures:

The performance impact of pg_tde by Percona for encrypted data pages is measurable across all tests, but not very large. The performance impact of encrypting WAL pages is about 20% for write-heavy tests. The tests were run with an extension RC (Release Candidate), however the WAL encryption feature is still in Beta stage.

Andreas also has a post on the testing specifics:

This test was run on a dedicated physical server, to avoid external influences and fluctuations from virtualization.

The server has a Intel(R) Xeon(R) Gold 5412U CPU with 48 cores, 256 GB RAM, and a 2 TB SAMSUNG MZQL21T9HCJR NVram disk dedicated for the tests (OS was running on a different disk).
