amrishlal opened a new pull request #6627:
URL: https://github.com/apache/incubator-pinot/pull/6627
## Description
A CSV file can contain fields that contain comma characters. Such a file
would be difficult to import as a table since comma is being used as a field
delimiter. Note that is not specific to comma character, but can happen with
any other delimiter character as well. This PR adds support for escaping
delimiters that appear within CSV fields so that they don't get confused with
actual delimiters.
Example CSV file with fields containing escaped comma delimiter:
```
id,name,json,ts
1,daffy duck,{"name":"daffy"\, "company":"linkedin"},0
```
