Description
Currently the CSV chunker can be the bottleneck in multi-threaded reads (starting from 6 threads, according to my experiments). One way to make it faster is to consider by default that CSV values cannot contain newline characters (overridable via a setting), and then simply search for the last newline character in each block of data.
