Editorial Standards

Last updated: August 31, 2026

DataEngineer Hub is a practitioner site, not a content mill. Every indexed article is written or signed off by Sainath Reddy, a data engineer based in Hyderabad who has spent the last several years on Snowflake, dbt, Airflow, and warehouse cost problems in production. This page is the rulebook for what goes live.

What we publish

Tutorials, architecture notes, cost breakdowns, and interview-style walkthroughs that come from work we have actually done: warehouse sizing mistakes, Cortex token bills, dbt model reviews, Time Travel recoveries, and SQL patterns that show up in interviews because they show up on the job. If a page cannot name a concrete failure mode, a number, or a decision we would make again, it does not ship as an article.

Interactive tools (cost calculators, SQL playground, format converters) and cheat sheets exist to support those articles. They are not substitutes for the article library.

What we will not publish

• Rewrites of vendor documentation with a new title
• Unreviewed AI drafts, spun articles, or scraped aggregations
• Pages whose only purpose is to rank for a keyword
• Thin listing pages with one or two cards and no original copy
• Duplicate URLs that 301 to a canonical article

Glossary terms and tool-vs-tool pages stay on the site as a working reference for readers. They are not the front door of the site and they are not treated as equivalent to original tutorials.

How an article is made

1. Source. A production note, a cost incident, a review comment, or a question that kept coming up at work.
2. Draft. Written in the author's voice. AI tools may help outline or check syntax. They do not publish unsupervised. See the disclaimer.
3. Review. Sainath checks technical claims, code samples, and whether the piece adds anything a first-page Google result does not already say.
4. Update. Pricing, exam blueprints, and warehouse features change. Articles carry a last-updated date. When a number is wrong, we fix the page rather than leave a stale screenshot up.

Guest writing

Guest authors appear on /contributors only after at least one piece has passed the same review and gone live. Pitches go through Write for Us. We reject generic overviews.

Corrections

If a query, credit rate, or exam detail is wrong, email [email protected] or use the contact form. We reply personally, usually within 24–48 hours on weekdays, India Standard Time, and we update the page when you are right.

Advertising

Ads, if shown, are separate from editorial. Sponsors cannot rewrite a tutorial to match a talking point. Affiliate links are disclosed in the disclaimer. Privacy details live on the privacy policy.
