I am not sure CSV is a pushdown-friendly format. There is no indexing, and in general (with quotes) the parser has to touch every byte. You can save perhaps on deserialization and memory allocation. Do you have an upper bound on how much you could save if everything that doesn't need to be done is free? I still find value in this implementation, e.g., as a model for other adapter implementations. -- This is an automated message from the Apache Git Service.
