Scaling through crisis: how infrastructure handled 1B messages in a single day
https://www.reddit.com/r/programming/comments/1nodab9/scaling_through_crisis_how_infrastructure_handled/

<!-- SC_OFF -->We recently published a piece on ShiftMag (a project by Infobip) that I think might interest folks here. It’s a candid breakdown of how Infobip’s infrastructure team scaled to handling 10 billion messages in a single day — not just the technical wins, but also the painful outages, bad regexes, and hard lessons learned along the way. <!-- SC_ON --> submitted by /u/shift_devs (https://www.reddit.com/user/shift_devs)

From Batch to Insights: How to Automate Data Validation Workflows
https://www.reddit.com/r/programming/comments/1np5m74/from_batch_to_insights_how_to_automate_data/

<!-- SC_OFF -->Hey r/programming (https://www.reddit.com/r/programming), I've been thinking a lot about the common pain points of dealing with unvalidated or "dirty" data, especially when working with large datasets. Manual cleaning is incredibly time-consuming and often a huge bottleneck for getting projects off the ground or maintaining data pipelines. It feels like a constant battle against inaccurate reports, compliance risks, and just generally wasted effort. Specifically, I'm looking into approaches for automating validation across different data types—like email addresses, mobile numbers, IP addresses, and even browser user-agents—for batch processing. Has anyone here implemented solutions using external APIs for this kind of batch data validation? What were your experiences? What are your thoughts on: * The challenges of integrating such third-party validation services? * Best practices for handling asynchronous batch processing (submission, polling, retrieval)? * The ROI you've seen from automating these processes versus maintaining manual checks or in-house solutions? * Any particular types of validation (e.g., email deliverability, mobile line type, IP threat detection) that have given you significant headaches or major wins with automation? Would love to hear about your experiences, cautionary tales, or success stories in building robust, automated data validation workflows!
