Kulkarni: TimescaleDB delivers query speeds 100x-1000x faster than MongoDB
“Given the same hardware, we're seeing not just higher insert performance, but hundreds to thousands of times faster queries.”
Ajay Kulkarni: Non-time-series data storage discards valuable state information
“And in fact, I would argue that not storing your data as time series is throwing away valuable information, because then you're losing how your data changed in the past, how it would be changing today, and how it might change in the future.”

Kulkarni: Web eventing and machine learning inferences are time-series data
“Web and mobile eventing data, again, is, is time series data, and even machine learning inferences are a source of time series data.”
Timescale pivoted from an IoT platform into a time-series database
“We have close to a 100,000 devices on our platform, and we need a place to store them, and, you know, and we tried a bunch of databases. It didn't work. Long story short, we just built our own time series database but we're still in the IoT business, and we fo…”
