SQL Server Insights from Production Environments

Practical observations and approaches from real-world SQL Server environments.

SQL Server in the Real World

SQL Server rarely becomes difficult because of one configuration setting or one badly written query. Problems usually emerge from the interaction between workload, architecture, infrastructure, configuration, and decisions that have accumulated over time.

This is where the articles on CraftedSQL start. They are based on practical experience from production environments and focus on understanding what is actually happening inside SQL Server before changing anything. Topics range from performance troubleshooting and query behavior to high availability, security, migrations, upgrades, and day-to-day database operations.

The goal is not to collect generic best practices. It is to explain how SQL Server behaves in real environments, why seemingly reasonable decisions sometimes create problems later, and how those situations can be analyzed systematically.

What You'll Find Here

Performance & Troubleshooting

Slow queries, blocking, resource pressure, execution behavior, workload-related problems, and the process of finding the actual root cause.

Architecture & Operations

High availability, migrations, upgrades, patching, infrastructure decisions, and the operational details that determine whether systems remain stable and maintainable.

Security & Reliability

Permissions, access patterns, configuration, operational safeguards, and the technical decisions that can turn into larger risks over time.

SqlClient Connection Pool V2: Faster Connections, New Questions for SQL Server Operations

An application can take longer than expected to become ready, even when the SQL Server behind it is performing normally. After a deployment or restart, several application components may request database connections almost simultaneously. SqlClient Connection Pool V2 targets precisely this kind of cold-start behavior. The database is available, authentication ...

When High Availability Becomes Critical: SQL Server in Essential Infrastructure

A hospital emergency department depends on much more than medical staff, diagnostic equipment and available treatment rooms. Behind everyday clinical processes, information systems exchange patient data, process laboratory results and deliver diagnostic findings to the people who need them. Most of these systems receive little attention as long as they ...

Vector Search in Production: Understanding the Limits of SQL Server 2025

A working SQL Server vector search demo is an encouraging result. The application stores embeddings, calculates similarities, and returns documents that appear relevant to the search. With SQL Server 2025, developers can combine this functionality with existing relational data without automatically introducing a separate vector database. But there is an ...

SQL Server Monitoring Without Alert Fatigue: From Metrics to Operational Decisions

A SQL Server can have a monitoring dashboard full of green indicators while users are already experiencing performance problems. CPU usage may remain within its configured limits, storage capacity looks sufficient, and all monitored services are running. Yet an important application process might take considerably longer than it did a ...

SQL Server Digital Sovereignty: Why Operational Control Matters

Digital sovereignty often becomes a discussion about location: Where does the SQL Server run? In which country does the organization store its data? Which company operates the underlying platform? Those questions matter when regulatory, contractual or internal governance requirements restrict where data may reside. They also matter when those requirements ...

SQL Server High Availability: Define the Failure Before Choosing the Technology

A SQL Server high availability discussion can turn into a technology discussion very quickly. Someone suggests an Availability Group, someone else prefers a Failover Cluster Instance, and before long the conversation is about synchronous replicas, shared storage, listeners and automatic failover. Those may all become relevant. But at that point, ...
Busy highway interchange as a metaphor for SQL Server execution plans and runtime context

SQL Server Execution Plans Need Runtime Context

SQL Server execution plans are often the first place I look when a query behaves differently from what I would expect. They tell me how SQL Server chose to access the data, which join strategies it selected and where estimates may not match what actually happened during execution. An actual ...

Azure Arc-enabled SQL Server: Visibility Before Migration

Azure Arc SQL Server can be useful long before an organization decides to move a database anywhere. In many SQL Server environments, there is an earlier problem to solve: before anyone makes a sensible decision about migration, consolidation or platform strategy, somebody needs to understand what is already there. That ...

A Restored Database Is Not the Same as a Recovered Service

A SQL Server restore can complete successfully while the business service behind it remains unavailable. The database may return to an ONLINE state, but that status only tells us something about SQL Server itself. SQL Server restore validation therefore needs to look further: can the application connect, are the required ...

When Permissions Outlive Their Context in SQL Server

Most SQL Server permissions begin with a perfectly reasonable decision. An application needs access to another database, a service account requires additional rights for a deployment, or an administrator receives broader permissions while a migration is in progress. At that point, the reason is probably known, and there may even ...
