There's a new CSV Parser in town. I've totally revamped DuckDB's CSV Parser. And it has a bunch of cool optimizations, such as state-machine parsing, a new parallelism strategy, implicit casting, projection pushdown, etc... All these improvements can result in a significant speed increase when compared to our previous parser. Depending on the machine and file, performance differences for single-file scans typically range from 2x to 4x. Below is the parsing time of a CSV file containing TPC-H's Lineitem data. Executed on my Mac M1 Max.
