[GitHub] [incubator-pinot] amrishlal opened a new pull request #6627: Allow escaping comma characters in CSV files.

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
   ```
   
   ## Upgrade Notes
   Does this PR prevent a zero down-time upgrade? (Assume upgrade order: Controller, Broker, Server, Minion)
   * [ ] Yes (Please label as **<code>backward-incompat</code>**, and complete the section below on Release Notes)
   
   Does this PR fix a zero-downtime upgrade introduced earlier?
   * [ ] Yes (Please label this as **<code>backward-incompat</code>**, and complete the section below on Release Notes)
   
   Does this PR otherwise need attention when creating release notes? Things to consider:
   - New configuration options
   - Deprecation of configurations
   - Signature changes to public methods/interfaces
   - New plugins added or old plugins removed
   * [ ] Yes (Please label this PR as **<code>release-notes</code>** and complete the section on Release Notes)
   ## Release Notes
   If you have tagged this as either backward-incompat or release-notes,
   you MUST add text here that you would like to see appear in release notes of the
   next release.
   
   If you have a series of commits adding or enabling a feature, then
   add this section only in final commit that marks the feature completed.
   Refer to earlier release notes to see examples of text
   
   ## Documentation
   If you have introduced a new feature or configuration, please add it to the documentation as well.

Review comment:
       Yes, the `\0` is a typo, it should either be `null` (which is the default in current master) or `\` (since that is the common escape character in use). From what I see, backward compatibility issues are minimal here, so setting escape character to `\`, but if there are good reasons to continue with `null`, we can do that.

       Yes, the `\0` is a typo, it should be `null` (which is the default in current master). Setting it to `\` leads to test case failures.

Review comment:
       Should we have a default escape character? Or use `null` as default? Current default will be `'\0'`
