Rinat Sharipov updated FLINK-10525:
-----------------------------------
Description:
Hi mates, in accordance with the contract of
*org.apache.flink.api.common.serialization.DeserializationSchema*, it should
return *null* value, when content couldn’t be deserialized.
But in most cases (e.x.
*org.apache.flink.formats.avro.AvroDeserializationSchema*) method fails, if
data doesn't satisfy expected schema.
We’ve implemented our own SerDe class, that returns *null*, if data doesn’t
satisfy schema, but it’s rather hard to maintain this functionality during
migration to the latest Flink version.
I think, that it’ll be useful feature, if Flink will support optional skip of
failed records in avro and other Deserializers
