Thanks Liamessentially, it would be an internal topic that we would be
creating to use as a cache store by accessing topic through a GlobalKTable,
so the problem you mentioned above for storing Hashmap may not apply there

Hi Pushkar,
Just wanted to say, as someone with battle scars from ActiveMQ and Camel,
there's very many good reasons to avoid Java serialization on a messaging
system. What if you need to tail a topic from the console? What if your
testers want to access in their pytests? Etc. And that's not even
And by the way, confluent has provided KafkaAvroSerializer/Deserialier.
Can't they be used to do conversion for java types?

Ok... so jackson json serialization is the way to go for hashmaps as well?

Oh, my mistake. I thought this was a different thread :)
You might want to check, but I don’t think there is a kip for a map serde. Of
course, you’re welcome to start one.
Thanks,

Hi Pushkar,
I don’t think there is. You’re welcome to start one if you think it would be a
useful addition.
Before worrying about it further, though, you might want to check the
InMemoryKeyValueStore implementation, since my answer was from memory.
Thanks,
John

John,
is there KIP in progress for supporting Java HashMap also?

Yes, that’s correct. It’s only for serializing the java type ‘byte[]’.

Thanks John... I got to finish the work in few days so need to get it
quick, so looking for something ready. I will take a look at jackson json.
By the way, what is the byteArrayserializer? As the name suggests, it is
for byte arrays so won't work for java ArrayList, right?

Hi Pushkar,
If you’re not too concerned about compactness, I think Jackson json
serialization is the easiest way to serialize complex types.
There’s also a kip in progress to add a list serde. You might take a look at
that proposal for ideas to write your own.
Thanks,
John

Won't say it's a good idea to use java serialized classes for messages, but
you should use a byteArraySerializer if you want to do such things

Hi All,
I have a requirement to store a record with key as java String and value as
java's ArrayList in the kafka topic. Kafka has by default provided a
StringSerializer and StringDeserializer, however for java ArrayList, how
can get serializer. Do I need to write my own? Can someone share if
12 matches
