Applicable scenarios​

HwameiStor provisions two kinds of local volumes: LVM and Disk. As a component of HwameiStor, Local Storage provisions two types of local LVM volumes, such as HA and non-HA.

For the non-HA local LVM volume, it's the best solution for data persistency in the following use cases:

  • Databases with HA capability, such as MongoDB, etc.
  • Messaging systems with HA capability, such as Kafka, RabbitMQ, etc.
  • Key-value stores with HA capability, such as Redis, etc.
  • Others with HA capability

For the HA local LVM volume, it's the best solution for data persistency in the following use cases:

  • Database, such as MySQL, PostgreSQL, etc.
  • Other applications which require the data with HA features.

Usage with Local Disk Manager​

Local Storage is a component of HwameiStor and must work with the Local Disk Manager module.

Roadmap​

Roadmap provides a release plan about local storage and its features.
