-----------------------------------

             Summary: Improve the CSV reading process
                 Key: FLINK-10684
                 URL: https://issues.apache.org/jira/browse/FLINK-10684
             Project: Flink
          Issue Type: Improvement
          Components: Core
            Reporter: Xingcan Cui


CSV is one of the most commonly used file formats in data wrangling. To load records from CSV files, Flink has provided the basic {{CsvInputFormat}}, as well as some variants (e.g., {{RowCsvInputFormat}} and {{PojoCsvInputFormat}}). However, it seems that the reading process can be improved. For example, we could add a built-in util to automatically infer schemas from CSV headers and samples of data. Also, the current bad record handling method can be improved by somehow keeping the invalid lines (and even the reasons for failed parsing), instead of logging the total number only.

This is an umbrella issue for all the improvements and bug fixes for the CSV reading process.
