------------------------------------------------------------
In addition, how it goes when one of HDD fails, could Kafka itself move the
general topic-partitions to SSD-mounted directories? Is there an internal
request or mechanism in Kafka that might lead to this situation? Many thanks!

> Ability to support heterogeneous storage in Kafka

> Key: KAFKA-7262
> URL: https://issues.apache.org/jira/browse/KAFKA-7262
> Project: Kafka
> Issue Type: Improvement
> Components: log
> Affects Versions: 2.0.0
> Reporter: fangbin sun
> Priority: Major
>
> 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.
