[jira] [Commented] (KAFKA-7262) Ability to support heterogeneous storage in Kafka

    [ https://issues.apache.org/jira/browse/KAFKA-7262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16574235#comment-16574235 ] 

huxihx commented on KAFKA-7262:
-------------------------------

As of Kafka 1.1, you could move key topic partition data to SSD-mounted directories using kafka-reassign-partitions.sh. Is that what you need?

> Currently we have a batch of servers, each broker has one SSD (1.5T) and ten HDDs (10T). For all I know, Kafka itself doesn't know much about the underlying hardware, it chooses the directory with the least number of partitions when creating a topic-partition.
> Is it possible to deploy a heterogeneous cluster for taking advantage of SSD with smaller disk capacity? Hope you all consider this. Any insights or guidance would be greatly appreciated.
