Ewen Cheslack-Postava commented on KAFKA-3803:
----------------------------------------------
And to further confuse things, Kafka Streams introduced an immutable Bytes
type:
https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/utils/Bytes.java
which is supposed to avoid both the pitfalls of using either byte[] (array
equality doesn't do what you want) and ByteBuffer (mutable, and I think
equality actually depends on current offset).
> JsonConverter deserialized Struct containing bytes field does not return true
> for equals()

> Key: KAFKA-3803
> URL: https://issues.apache.org/jira/browse/KAFKA-3803
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 0.10.0.0
> Reporter: Ewen Cheslack-Postava
>
> The problem is that byte[] comparisons will return false for equality, so
> even if the two are effectively equal, Struct.equals will not return true.
> It's unclear if this should be fixed or not. Equality wouldn't work for map
> or array types containing bytes either. However, on possibility is making
> ByteBuffer the default instead to alleviate this, although then we may end up
> with asymmetry in equality.
