Subject [jira] [Commented] (KAFKA-1658) Overriding #of partitions per topic, does not take effect
Date Wed, 01 Oct 2014 00:03:28 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-1658?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14154059#comment-14154059

aarti gupta commented on KAFKA-1658:

Is there a way (programatic or otherwise) to set the # of partitions for a given topic.
For example topic A has 3 partitions, whereas topic B has 5 partitions

>                 URL: https://issues.apache.org/jira/browse/KAFKA-1658
>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions:
>         Environment: Ubuntu
>            Reporter: aarti gupta
> Tried to change the # of partitions per topic, (for a non existent topic), by adding
the following settings to the producer
>       properties.put("num.partitions","3");
>         properties.put("topic.partition.count.map", "3");
>         ProducerConfig producerConfig = new ProducerConfig(properties);
>         producer = new Producer<String, String>(producerConfig);
> Also set         properties.put("auto.create.topics.enable", "false"); (tried without
that first)
> The default # of partitions as specified in the server.properties (i.e. 1) still come
into effect.
> I also wanted to change the replication factor, (for a non existent topic), 
>         properties.put("default.replication.factor", "3");  on the producer config did
not work
> Is this expected behavior? The documentation suggests that we use the command line tool,
but I want to control this dynamically. Any suggestions?
