From Tutorials to AI: Approach Technical Documentation From a Different Angle
The only thing more abundant than coffee in a developer’s life is, well, technical documentation. It seems simple enough – you have a problem, you go through a few pages, and get your answer, that simple. Is it, though? Anyone who’s ever tumbled down the rabbit hole of Stack Overflow threads at 2 AM or squinted at API docs with the growing suspicion they’re written in an ancient, forgotten dialect will tell you: not quite.
Tutorials skip crucial steps, reference guides resemble dense textbooks, and help forums, while helpful, can send you on a wild goose chase for that one golden nugget of information. But there’s a light in the tunnel, and we’re here to help you find it.

‘OR’ and ‘IS NULL’ Might Be Holding You Back
Where “OR” and “IS NULL” condition frolic unchecked, queries often find themselves stumbling down the performance rabbit hole—a place where CPU cycles burn faster than a comet tail and I/O operations multiply with the fervor of rabbits in spring.

The Nightmare of Database Deadlocks
A database deadlock occurs when two or more transactions in a database system hold locks on resources the others need. Each transaction waits for the others to release their locks, and just like two drivers who are not sure who has the right of way, none can proceed.
It would be lovely to be able to enumerate the causes of a database deadlock and address all of them. Sadly, it’s way too complex. It can be said, though, that a database deadlock is most likely to stem from poor application design, lack of proper transaction management, or the inevitable complexity of highly concurrent systems.

Adapt or Perish: Change Management
Business is the track we’re all riding on. It zigs, it zags, and just when you think you’ve got a straight shot, it throws you for a loop. From the ups brought by technological innovation to the subtle tremors of consumer preference, change keeps the wagon moving. Without it, our tale of commerce and industry would be as dull as a car ride to the nearest shop.
Businesses that treat change like an unwelcome guest at the party are the ones that end up sitting alone in the corner. The real movers and shakers are the ones who invite change to dance, anticipating its moves and stepping in time.

Shifting Gears to Real-Time: How One Company Overcame Its Data Dilemma
Today’s story is about a leader in the automotive spare parts market, spanning 17 European countries, grappling with a significant challenge. They faced the daunting task of managing delayed reporting, ensuring consistency across diverse markets, and customizing reports with limited flexibility. This scenario led to delayed data updates. This, in turn, caused frustration and inefficiency.

Execution Plan Changes in SQL Server: Reasons and Solutions
Executions plan—complex maps charted by the SQL Server optimizer, dictate the most efficient route for data retrieval. However, the plans are not static. They morph and adapt, influenced by a host of factors ranging from data volume changes to system upgrades. Each of the execution plan changes in SQL Server has the potential to sway performance dramatically.
Understanding the reasons behind these shifts, and more importantly, how to effectively manage them translates to maintaining optimal performance in SQL Server environments.

The Domino Effect in the T10 Database on g1rush Server
Performance issues rarely occur in isolation. Often, a single problem can trigger a cascade of related issues, each compounding the overall impact on the system. This case study explores such a scenario in the T10 database on the g1rush server.

From Analysis to Action: Overcoming Execution Plan Changes
Execution plans choose the way in which SQL queries are executed by the database engine. As such, they are a difference between a smoothly running database and one that stumbles under load. Sometimes, an execution plan changes, for various reasons—often silently and without warning—and the far-reaching fallout can be huge.
The most immediate impact seen as the execution plan changes is a decline in query performance. A query that once ran smoothly in milliseconds might, due to an altered plan, start consuming seconds. This increase in query time can cascade into longer load times for applications, frustrated end-users, and severe financial repercussions in high-stakes environments such as financial trading platforms or real-time data services.

The Most Important Database Performance Metrics
If no one sees the database issues, do they really happen? – Contrary to the popular philosophical dilemma, this question can be answered quite easily – Absolutely yes. Unseen or unmonitored problems in database systems do occur and can indeed cause significant disruptions. It doesn’t matter if they’re not immediately apparent. Without monitoring of the database performance metrics and proactive management, these underlying issues can compound, leading to decreased performance, potential data loss, and even system failures that by their nature demand urgent and often extensive interventions to rectify.
The cost of ignoring database performance metrics is just too great.

The Story of Locks by Application Issues
On the 20th of April, query load times usually ranged from 12 to 15 seconds per snapshot, but there was a notable spike exceeding 2,000 seconds during certain periods. This anomaly suggested a deeper issue, prompting a detailed investigation. By examining the correlation between locks and application issues, executions, disk reads, and buffer writes, a significant overlap was found between increased query durations and intensified locking issues. Accessing the lock history tab provided detailed data on each lock event, including the time, duration, and specific database elements affected.
