----------------------------------
Summary: Add storage partition online
Key: ROCKETMQ-27
URL: https://issues.apache.org/jira/browse/ROCKETMQ-27
Project: Apache RocketMQ
Issue Type: New Feature
Components: rocketmq-store, rocketmq-tools
Affects Versions: 4.1.0-incubating
Reporter: Zhanhui Li
Assignee: yukon
RocketMQ broker stores all messages before they are expired, which requires
pretty much storage for a high load system. For now, the message store can be
configured to use only one partition. Quite often, we find broker runs out of
storage as business expands quickly. Online resizing a partition most of time
is not possible(with absence of LVM) whilst attaching a new disk/partition in
cloud environment is super easy.
It would be nice for RocketMQ to be capable of adding extra commit log store
path online, allocating commit log files onto partitions based on
free/available space.
