SQL Performance

AUGUST 23, 2019

In traditional row-mode execution plans, SQL Server may introduce a Bitmap operator as part of performing early semi join reduction before a parallel hash or merge join. There have been major improvements since the first appearance of the batch mode execution engine in SQL Server 2012. Background. The Query Optimizer. Bitmap Choice.

But with the complexity that comes with digital transformation and cloud-native architecture, teams need a way to make sure applications can withstand the “chaos” of production. Dynatrace news. Testing for mishaps you can predict is essential. Thus, the tool Chaos Monkey was born. Know the starting state of your environment.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory.

Some of the built-in features ( wal_compression ) have been there since 2016, and almost all backup tools do the WAL compression before taking it to the backup repository. Zstd can be chosen if the server load is not CPU bound because it can give us better compression at the expense of more CPU utilization.

SQL Server According to Bob

JUNE 9, 2016

SQL Server, as outlined in the following post ( [link] ) adjusts to various processor configurations. I have received questions related to how SQL Server accomplishes the alignment on both bare metal and VM installations. SQL Server uses Windows APIs to determine the processors and package interactions. GetSystemInfo [link].

Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. In 2016, Jio swept over the subcontinent like a monsoon dropping a torrent of 4G infrastructure and free data rather than rain.

Microservices architecture. Monolithic architecture takes a back seat with headless CMSes. Omnichannel. For content authors.

You will get add-ons like server-side rendering, routing and more. The DOM structure is surrounded by Inferno for browser/server edits.

One distinct trend is a belief that a JavaScript framework and Single-Page Architecture (SPA) is a must for PWA development. Late-loading JavaScript can cause “server-side rendered” pages to fail in infuriating ways. The true median device from 2016 sold at about ~$200 unlocked. What’s going on here?
