For professionals handling large-scale IoT implementations, what’s your go-to architecture for ingesting, cleaning, and analyzing streaming sensor data in near real-time? How do you manage latency, data quality, and event processing, especially across millions of devices?

In large relational databases, complex queries involving multiple joins, subqueries, and window functions often become slow. What indexing strategies, query rewrites, or execution plan tricks do you use to improve performance while maintaining query accuracy?

I’m exploring best practices in designing data pipelines and want to understand how different teams handle computationally intensive transformations. Some advocate for doing it early during ETL to keep models clean and fast, while others prefer flexibility and defer transformations to the modelling stage. Curious to hear what’s worked for others and why.

Hi Data World, 

Im a new business owner , and have opened up my barbershop for 4 months now. I have been in the industry for 15 years, and realize the power of data.

• How it can influence behavior and help structure the business. I wanted to hear some feedback from you guys, on how you think data management can help a salon business grow to be more exponentially successfull?
• Which KPI are the most important?
• Which key visualizer can help broadcast the data to be more easily understood (from numbers to graphs).
• would love to hear some thoughts from the data world as i see its growing and increasingly more relevant now with the development of technologies

Thanks, 

Mike
