Sul canale SQLPASS TV, continua la pubblicazione delle sessioni erogate al PASS Summit 2011. Questa settimana è stata pubblicata la sessione “Query Tuning Mastery: Zen and the Art of Workspace Memory” tenuta da Adam Machanic.

Abstract

As SQL Server professionals, we often think of memory in vague, instance-level terms: buffer pool, procedure cache, Virtual Address Space, and so on. But certain tasks require a more in-depth focus, and query tuning is one of them. Large, complex queries need memory in which to work –workspace memory– and understanding the how’s, when’s, and why’s of this memory can help you create queries that run in seconds rather than minutes. This session will teach you how to guide the query processor to grant enough memory for top performance, while also keeping things balanced for the sake of concurrency. You will learn advanced monitoring techniques, expert-level application of specialized query hints, and the memory internals needed to put it all together. If you work with large queries and are serious about achieving scalability and consistently great performance, you owe it to yourself to attend this session.

Abstract

Dates and times seem simple at first. Kendra Little will show you there’s more to it than you think. She’ll give you five best practices that will help you select the right temporal data type, avoid common issues, and use the most effective techniques to aggregate data. She’ll also explain painful problems with query performance and how to avoid them. Choose wisely: the correct types and high performing data access logic will scale like magic.

Sul canale SQLPASS TV, continua la pubblicazione delle sessioni erogate al PASS Summit 2011. Questa settimana è stata pubblicata la sessione SQL Server Execution Plans (From Compilation to Caching to Reuse) tenuta da Maciej Pilecki (SQL Server MVP, MCM).

Abstract

Execution plan reuse is one of the most important aspects of building well-performing and scalable SQL Server solutions. But it’s also the one that is often overlooked during the design phase and becomes very difficult to troubleshoot later. In this session we will discuss in details the following aspects of SQL Server execution plans: compilation, re-compilation, parameterization, caching, reuse and aging. You will leave this session with full understanding of how to improve your server’s performance by increasing execution plan reuse (and how to avoid reuse in case this is necessary).

Stati resi pubblici a tutti, non solo ai partecipanti, una selezione di 10 sessioni del PASS Summit 2012. Tra le sessioni si trovano vere e proprie perle come quella di Bob Ward sugli internals di SQL Server 2012, giusto per citarne una che contiene informazioni altrimenti introvabili
