trinodb/trino
Trino is an open-source engine that lets companies ask complex questions across massive amounts of data stored in different places, all using standard SQL — the same query language used in most databases. Instead of moving data into one central location, Trino connects directly to wherever the data lives and returns answers fast, even when dealing with billions of records.
§ 1 — why it matters
For any company sitting on large amounts of data spread across multiple storage systems, Trino eliminates the need to build expensive, time-consuming data pipelines just to run business intelligence or analytics — dramatically cutting costs and time-to-insight. With over 13,000 stars and 1,100+ contributors, it has become a foundational piece of the modern data stack, meaning building on or integrating with it gives products instant credibility and a massive existing user base.
