Summary: Skip null values in SimpleStringSchema#deserialize (was: Skip
null values in SimpleStringSchema)
> Skip null values in SimpleStringSchema#deserialize
> --------------------------------------------------
>
> 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
> Priority: Major
>
> 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.
