SQL Performance

JANUARY 22, 2020

Table-valued parameters have been around since SQL Server 2008 and provide a useful mechanism for sending multiple rows of data to SQL Server, brought together as a single parameterized call. The DataTable can be created multiple ways in the.NET code, but a common way to create the table is something like the following: System.

The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).

Still, if you stack a bunch of high-transaction databases on there, checkpoint processing can get pretty sluggish. If you have instances running older versions like SQL Server 2008 R2 (I found one!), And none of these FlushCache messages were ever paired with the 15 second I/O warnings in the error log. I still have more to do.

Now we have a problem statement that we can reason about: why are large chunks of our code segment filled with zeroes? It’s frustrating to leave your computer running tests overnight only to have crashes pollute the results. In this case it said that 9322 bytes in the code in the crash dump were wrong. failure rate.

Anyone who cares to download and fork the code can do so. From 2008 to 2013, the Chrome project was based on WebKit, and a growing team of Chrome engineers began to contribute heavily "upstream." This process can be messy and slow, but it never creates a political blockage for developing new capabilities for the web.

It uses a Solaris Porting Layer (SPL) to provide a Solaris-kernel interface on Linux, so that unmodified ZFS code can execute. There's also a ZFS send/recv code path that should try to use the TASK_INTERRUPTIBLE flag (as suggested by a coworker), to avoid a kernel hang (can't kill -9 the process). LTS (April 2016).

Over the last few years we’ve talked a lot about how at Dynatrace we have changed our development processes in order to deploy new feature releases with every sprint, as well as providing a fast-lane to production that allows us to deploy important updates to our customers within an hour. Dynatrace news. I have a new idea.

When he first gave the presentation in 2008, he was working at this massive company called Yahoo! And so it’s important to continually invest in stability, in strong infrastructure, in stable code, so that we have that strong platform to stand on as the next thing happens. That was 2008. I remember going through this with CSS.

SQL Server According to Bob

JANUARY 26, 2017

My goal is to resolve mysteries about SQL Server I encounter but do this without going straight the source code first. Quick question about a behavior we’re seeing at a customer and in testing. The process to enable this for a database is described in our documentation. In my test I did not hit the breakpoint.

Tool 1: Dolly the Sheep Companies that are heavily rule-based - think insurance - eagerly moved their business rules into code. It was easy to move into code; it's just as easy to move it back into human-readable format. A clone of something extinct - our lost business knowledge - runs the risk of suffering severe defects.

A brief history of IPC at Netflix Netflix was early to the cloud, particularly for large-scale companies: we began the migration in 2008, and by 2010, Netflix streaming was fully run on AWS. For Inter-Process Communication (IPC) between services, we needed the rich feature set that a mid-tier load balancer typically provides.
