Flink Jira Bot updated FLINK-23953:
-----------------------------------
    Labels: Avro AvroSchema pull-request-available stale-major  (was: Avro 
AvroSchema pull-request-available)

I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help 
the community manage its development. I see this issues has been marked as 
Major but is unassigned and neither itself nor its Sub-Tasks have been updated 
for 60 days. I have gone ahead and added a "stale-major" to the issue". If this 
ticket is a Major, please either assign yourself or give an update. Afterwards, 
please remove the label or in 7 days the issue will be deprioritized.

>             Project: Flink
>          Issue Type: Bug
>          Components: API / Type Serialization System
>    Affects Versions: 1.13.2
>            Reporter: Iaroslav Zeigerman
>            Priority: Major
>              Labels: Avro, AvroSchema, pull-request-available, stale-major

> The problematic code is located 
> [here|https://github.com/apache/flink/blob/release-1.13.2/flink-formats/flink-avro/src/main/java/org/apache/flink/formats/avro/typeutils/AvroSerializerSnapshot.java#L194].
>  Returning COMPATIBLE_AFTER_MIGRATION seems completely unnecessary and causes 
> issues during schema evolution. The COMPATIBLE_AS_IS status should be 
> returned instead. Even the comment right above the shared snippet suggests 
> that:
> {noformat}
>                     // The new serializer would be able to read data 
> persisted with *this*
>                     // serializer, therefore no migration
>                     // is required.
> {noformat}
