Thanks all for this.
Las question around this.
If I write scripts for topics, I am afraid it will change partitions for
some default/internal system created topics which I don't want,
In that Case, I guess, I have to filter topic list first and then provide
it to the script...
is that correct?
Or if you don’t want to automate then , use the excel sheet and generate below
command for all topic .
Put all 350 statement in script and run it .

Hi Sunil,
You'd want to do a bit of shell scripting for this.
for topic in $(./kafka-topics.sh --bootstrap-server your-kafka-here:9092
--list); do
./kafka-topics.sh --bootstrap-server your-kafka-here:9092 --topic $topic
--partitions X --alter
done
Etc. etc. And yep, to make sure further auto

You can’t use a wildcard and must address each topic individually. You can
automate it with a for loop that takes an array/list of topics as the item to
iterate over.

Is there any possibility I can use any wild cards?

You can use below command to alter to partition
./bin/kafka-topics.sh --alter --zookeeper localhost:2181 --topic my-topic
--partitions 6
Thanks

Hi,
I already have 350 topics created. Please guide me how can I do that for
these many topics?
Also I want each new topic to be created with more number partitions
automatically than previous number 3, which I had set in properties.
Regards,
Sunil.

Hi Sunil,
The broker setting num.partitions only applies to automatically created
topics (if that is enabled) at the time of creation. To change partitions
for a topic you need to use kafka-topics.sh to do so for each topic.
Kind regards,

Hi,
I want to change number of partitions for all topics.
How can I change that? Is it server.properties which I need to change?
Then, in that case I have to restart broker right?
I checked from confluent control center, there is no option to change
partitions.
Please advise.
Regards,
Sunil
