[jira] [Created] (FLINK-19652) Support pure string format for Kafka
table connector
Qingsheng Ren created FLINK-19652:
-------------------------------------
Summary: Support pure string format for Kafka table connector
Key: FLINK-19652
URL: https://issues.apache.org/jira/browse/FLINK-19652
Project: Flink
Issue Type: New Feature
Components: Connectors / Kafka, Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Affects Versions: 1.11.2, 1.11.1, 1.11.0
Reporter: Qingsheng Ren
Currently Kafka table connector supports some formats including CSV, JSON, Avro etc., but there are still cases that users want to deserialize the entire record as a string and parse with UDTF by themselves.
A hacky way is defining a Kafka source table with only one string column and still using CSV format, but to use a character that will never appear in the message as the field delimiter. Actually it's hard to find such a delimiter if user cannot control the source of data.
