--------------------------------
Summary: Skip null values in SimpleStringSchema
Key: FLINK-23727
URL: https://issues.apache.org/jira/browse/FLINK-23727
Project: Flink
Issue Type: Bug
Components: Connectors / Common
Affects Versions: 1.13.2
Reporter: Paul Lin
In Kafka user cases, it's valid to send a message with a key and a null payload
as a tombstone. But SimpleStringSchema, which is frequently used as a message
value deserializer, throws NPE when the input value is null. We should tolerate
null values in SimpleStringSchema (simply return null to skip the records),
otherwise users need to implement a custom one.
