McKinsey: The state of AI in 2022—and a half decade in review
McKinsey publishes the state of AI in 2022 with the last five years’ review. A few highlights
63 percent of respondents say they expect their organizations’ investments to increase in AI over the next three years.
Today, the biggest reported revenue effects are found in marketing and sales, product and service development, and strategy and corporate finance, and respondents report the highest cost benefits from AI in supply chain management
The tech talent shortage shows no sign of easing, threatening to slow that shift for some companies. A majority of respondents report difficulty in hiring for each AI-related role in the past year, and most say it either wasn’t any easier or was more difficult to acquire this talent than in years past
Jacob Matson: Modern Data Stack in a Box with DuckDB
One important characteristic of the data infrastructure is that the more recent the data more frequent the access. Given the characteristic, are we having a “Big Data” problem? Can we spin off a machine with all the data stack and run through the analysis? The author writes an exciting blog, Modern data stack in a Box!!

Percona: JSON and Relational Databases – Part One
Whether we like it or not, most data engineering and modeling challenges will be handling semi-structured data in the coming years.
SaaS companies like Salesforce and Zendesk are increasingly processing and emitting sem-structure data. We have already seen systems like Apache Pinot; Apache Druid improves their JSON support. The Percona blog walkthrough JSON support in the relational databases.

Neil Raden: We need a real semantic layer - but something is missing
Will the semantic layer induce more challenges than the problem it solves? The author explains the problem with customer mapping. Who is a customer? The question remains the same but will have a different answer from marketing, sales, and products. The author gives a fresh perspective to the semantic layer!!

Monzo: Building an extension framework for dbt
Possibly one of the most brilliant pieces of engineering I read this year
Kudos to the Monzo data team. The blog narrates bringing a platform approach to dbt, lessons learned, tracking back, and pragmatic hacking into dbt core to build the extension framework; A great joy to read.
I hope we will see dbt-core support the extension framework out of the box

Shopify: 3 (More) Tips for Optimizing Apache Flink Applications
Shopify writes three more practical tips for optimizing Apache Flink. TIL about the Hybrid Source support from Apache Flink and the role in Backfilling. I recently had to design for a similar problem and vaguely arrived at a similar strategy, but I thought it might be complicated. Seeing Shopify implement it gives much hope to explore the option further. Thank you, Shopify data team.
