Jeff Klukas updated KAFKA-4932: ------------------------------- Summary: Add UUID Serde (was: Add UUID Serdes) > Add UUID Serde > -------------- > > Key: KAFKA-4932 > URL: https://issues.apache.org/jira/browse/KAFKA-4932 > Project: Kafka > Issue Type: Improvement > Components: clients, streams > Reporter: Jeff Klukas > Priority: Minor > > I propose adding serializers and deserializers for the java.util.UUID class. > I have many use cases where I want to set the key of a Kafka message to be a > UUID. Currently, I need turn UUIDs into strings or byte arrays and use the > associated Serdes, but it would be more convenient to serialize and > deserialize UUIDs directly. > I'd propose that the serializer and deserializer use the 36-byte string > representation, calling UUID.toString and UUID.fromString > Optionally, we could also has the deserializer support a 16-byte > representation and it would check size of the input byte array to determine > whether it's a binary or string representation of the UUID. It's not well > defined whether the most significant bits or least significant go first, so > this deserializer would have to support only one or the other. > Optionally, there could be two variants of the serializer, a > UUIDStringSerializer and a UUIDBytesSerializer. > We would also wrap these in a Serde and modify the Serdes class to include > this in the list of supported types. > I would be willing to write this PR, but am looking for feedback about > whether there are significant concerns here around ambiguity of what the byte > representation of a UUID should be, or if there's desire to keep to list of > built-in Serdes minimal such that a PR would be unlikely to be accepted. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
