I read the A Comprehensive Guide to the Distributed SQL Query Engine Trino.
- SQL query engine
- Supports ANSI SQL
- Federated queries
- Allows referencing and using databases and schemas from different systems with the same SQL
- Not a database
- Not designed for processing OLTP
- Since it is aimed at OLAP, the performance targets are likely at the OLAP level
- The ability to scale computing resources as a distributed system resembles the nature of New SQL
- Handles data sources in a way that differs from traditional big data approaches (which require various query languages and tools, along with costly operational and maintenance expenses for data warehouses)
