In the realm of memory-optimized tables, every table must have at least one index to connect its rows. Notably, every index on such tables is also memory-optimized. Among the various types of indexes available, hash indexes stand out for their unique structure and functionality. Understanding the importance of bucket counts in hash indexes for memory-optimized tables is crucial for maintaining optimal performance in SQL Server. This post looks at the structure of hash indexes, how to specify and adjust bucket counts, and the consequences of incorrect bucket counts. Learn best practices for planning and optimizing your hash indexes to ensure efficient data management and avoid common performance pitfalls.

Automated Database Health Checks: Leveraging SMO in PowerShell
Safeguard your databases with automated PowerShell scripts! This guide walks you through creating scripts to check critical database health metrics like size and free space. Learn how to connect to SQL Server and format results for clarity. The post also explores optional features for enhanced functionality.
Optimizing Large Tables in SQL Server Using Table Partitioning
SQL Server table partitioning is an invaluable feature for improving database performance and management, especially for large-scale databases. This blog post provides an overview of setting up and managing partitioned tables in SQL Server, using TSQL commands. Partitioning helps manage large tables by dividing them into smaller, more manageable segments known as partitions. Each partition can be stored on a separate filegroup, enhancing query performance and simplifying maintenance tasks such as backups and index rebuilds.
Ensuring Optimal Execution Plans in SQL Server
Explore professional strategies for managing SQL Server Plan Regression. This guide offers insight into preventing performance degradation through efficient execution plan selection and maintenance, ensuring optimal query performance in SQL Server environments.
Preventing Page Splits with Optimal Fill Factor Settings
The SQL Server Fill Factor is a setting that can be applied to indexes, which determines the amount of space to leave empty within the index pages. This setting is crucial for managing how densely SQL Server stores the index data on each page. It’s primarily used to improve performance and reduce page splits during insert or update operations that modify the index. The Fill Factor is specified as a percentage value.
Mastering Resource Governance for SQL Server Agent Jobs
Have you ever found yourself in a situation where certain SQL Server Agent jobs are taking up more than their fair share of CPU resources? It’s a common scenario in the world of database management, where jobs essential to your database’s functionality end up hogging the limelight, so to speak. The Resource Governor (RG) is a powerful tool in SQL Server’s arsenal, designed to help you manage these situations. However, applying it effectively, especially to SQL Agent jobs, can be a bit tricky. This blog dives deep into the mechanics of Resource Governor and offers practical advice on managing your SQL Agent jobs efficiently.
Automating SQL Server Database Refreshes with PowerShell
In today’s agile software development environment, keeping lower environments like development and testing synchronized with production data is essential. It not only helps in identifying issues early but also ensures that features are developed and tested against the most current dataset. This blog introduces a PowerShell script that automates the process of refreshing a SQL Server database in lower environments using a “copy only” backup from a production environment. By diving into the script, we aim to shed light on how automation can simplify database management tasks, making them more efficient and error-resistant.
Automating SQL Server Index Maintenance with PowerShell
In this blog post, we’ll focus on automating index maintenance using PowerShell. We’ll present a complete script to assess index fragmentation and perform necessary maintenance tasks, followed by a detailed explanation of each part of the script, showcasing how PowerShell can be a powerful tool in the arsenal of any SQL Server administrator.
The Power of Snapshots: Exploring Copy-On-Write in SQL Server
“Copy-On-Write” (COW) is a resource management technique used in computer programming and operating systems. Its application in SQL Server, particularly in relation to snapshot technologies, is a fundamental concept behind the functioning of database snapshots and certain types of backups. Let’s delve into the detailed workings of Copy-On-Write in the context of SQL Server:
