does kafka support reducing topic partitions on the fly?

Hi All,

I have a question around reducing topic partitions on kafka. Currently, all
topics are 6 partitions. I want to reduce it to 3 for some of the topics.
Is this supported by kafka without deleting the topic?

Hi Pushkar,
I don't think so. Per https://kafka.apache.org/documentation/, "Kafka does
not currently support reducing the number of partitions for a topic.".
