------------------------------------------
Summary: Change the default "default serde" from ByteArraySerde to
null
Key: KAFKA-9559
URL: https://issues.apache.org/jira/browse/KAFKA-9559
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Sophie Blee-Goldman
Fix For: 3.0.0
The current default "default serde" is not particularly useful, and in almost
all cases is intended to be overwritten either by setting the config explicitly
or by specifying serdes directly in the topology. If a user does not set the
config and misses specifying a serde they will get a runtime ClassCastException
once they start processing unless they are in fact processing only bytes.
We should change the default default to null, so that an exception will instead
be thrown immediately on startup if a user failed to specify a serde somewhere
in their topology and it falls back to the unset default.
