This makes sense as the underlying databases generally have special indexes and data that are stored in a specific format to optimize the read time. substr(char[20],1,100) now returns a string with length 20 The goal in most optimizations for Trino is to push down the query to the database and only get back the smallest amount of data needed to join with another dataset from another database, do some further Trino specific processing, or simply return as the correct result set for the query. user.name is not double quoted .

Trino is just a query engine and does not store data.
Not only are you able to run ad-hoc and federated queries over disparate data sources, but now you can also run the infrastructure for those queries on-demand with almost no cost to your engineering teams time. Unless you are in a company that houses a massive data platform and you have dedicated data and DevOps engineers to each system in your platform, many of these options wont be feasible for you in the long run.
