-----------------------------------
Summary: Allow comments in CSV format without having to ignore
parse errors
Key: FLINK-21583
URL: https://issues.apache.org/jira/browse/FLINK-21583
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table
SQL / Ecosystem
Affects Versions: 1.12.1
Reporter: Nico Kruber
Currently, when you pass {{'csv.allow-comments' = 'true'}} to a table
definition, you also have to set {{'csv.ignore-parse-errors' = 'true'}} to
actually skip the commented-out line (and the docs mention this prominently as
well). This, however, may mask actual parsing errors that you want to be
notified of.
I would like to propose that {{allow-comments}} actually also skips the
commented-out lines automatically because these shouldn't be used anyway.
