Draft to show what usage of the new Read API in cloudquery/plugin-sdk#542 will look like in practice.
It's easy to implement for databases, but not so trivial for files. However, this shows that it can be done for files without loading the entire file into memory (as long as there is a limit on the number of results returned). Most of the code is around implementing a priority queue to limit memory usage while sorting results for CSV.
