SQL Server Index Optimization Strategies: Best Practices with Ola Hallengren’s Scripts

DZone

Index maintenance is a critical component of database administration as it helps ensure the ongoing efficiency and performance of a Structured Query Language (SQL) Server environment. Over time, as data is added, updated, and deleted, index fragmentation can occur, where the logical and physical ordering of index pages becomes misaligned. This fragmentation can lead to increased disk I/O, decreased query performance, and overall system inefficiency.

Living in the future: Using C++26 at work

Sutter's Mill

I recently contributed a guest post on my employer’s blog about the importance of the almost-feature-complete C++26 draft standard: “Sea change in C++: Why opportunities abound” It starts by summarizing a talk I gave recently, about how C++26 is poised to do what C++11 did over a decade ago: usher in a new era of C++ code style. Just as we can now glance at 10 or 20 lines and quickly recognize modern C++ as C++11-era code, soon well be able to do the same with code that uses st

Getting Started With Queryable Encryption in the MongoDB C# Driver

The Polyglot Developer

With the release of MongoDB 7.0 in August 2023, we introduced a feature called Queryable Encryption , the first of its kind. With queryable encryption, your data is encrypted, even at rest, with the server unable to read it either but still able to execute queries against it. You can specify what fields to encrypt so you can encrypt as much or as little of your document as you need.
