…arators. (apache#37687) Supports reading CSV data using LF and CRLF as line separators. csv file: ``` 1,abc 2,def\r 3,qwe 4,hello\r ``` if you `set keep_carriage_return = false` you will get : ```mysql 1 abc 2 def 3 qwe 4 hello ``` Here, both \r\n and \n are used as delimiters. if you `set keep_carriage_return = true` you will get : ```mysql 1 abc 2 def\r 3 qwe 4 hello\r ``` Here only \n is used as a delimiter. It should be noted that `set keep_carriage_return = true` is valid for tvf, but not for stream load/mysql load. This means that when you perform stream load/mysql load, crlf and lf will be automatically used as delimiters, even if you `set keep_carriage_return = true`.

Proposed changes
Supports reading CSV data using LF and CRLF as line separators.
csv file:
if you
set keep_carriage_return = falseyou will get :
Here, both \r\n and \n are used as delimiters.
if you
set keep_carriage_return = trueyou will get :
Here only \n is used as a delimiter.
It should be noted that
set keep_carriage_return = trueis valid for tvf, but not for stream load/mysql load. This means that when you perform stream load/mysql load, crlf and lf will be automatically used as delimiters, even if youset keep_carriage_return = true.
