------------------------------
Assignee: tartarus
> Support for reading fields that do not exist in Parquet files
> -------------------------------------------------------------
>
> Key: FLINK-23715
> URL: https://issues.apache.org/jira/browse/FLINK-23715
> Project: Flink
> Issue Type: Improvement
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
> Reporter: tartarus
> Assignee: tartarus
> Priority: Major
> Labels: pull-request-available
>
> In a production environment, it is often encountered that users add fields to
> the hive table, but do not refresh the data of the historical partition.
> Therefore, if the new field is not in the historical partition file, an error
> will be reported when reading the historical partition.
> General users would expect that if there is no such field, then fill in null
> and return.
> The current flink Parquet format does not support this function.
