Yonik Seeley commented on SOLR-1925:
------------------------------------
I took a quick look... here are some of the issues I see:
- loses info by removing newlines
- always encapsulates with quotes - not as readable
- doesn't escape encapsulator in values
- doesn't escape separator in multi-valued fields
- isn't really nested CSV, so it's not compatible with the CSVLoader
- uses System.getProperty("line.separator")... we should avoid different
behavior on different platforms
- doesn't stream documents (dumping your entire index will be one use case)
- performance: patterns shouldn't be compiled per-doc

> As part of some work I'm doing, I put together a CSV Response Writer. It
> currently takes all the docs resultant from a query and then outputs their
> metadata in simple CSV format. The use of a delimeter is configurable (by
> default if there are multiple values for a particular field they are
> separated with a | symbol).
