v3.0.0

Summary of changes:

• In this release, we have made several significant updates to improve write performance and user experience.
  • We have revised our implementation of key-value store that translates key-value pairs in the request to block layer data written to device.
  • Specifically, we have replaced RocksDB with an internal implementation of a hash-based key-value translator and a hint-based logical block manager sensitive to optimal NVMe drive IO boundary to improve write performance.
• For impacted users, these updates should provide a smoother, more intuitive experience with a noticeable improvement to write operation.
  • We have deprecated compaction and the requirement for written data to be compacted before reading to achieve maximum read performance is no longer needed.
  • We have introduced a new format tool called dss-formatter to format devices; similar to existing mkfs-blobfs tool which has now been deprecated.

Limitations

• Persistent key listing is not yet implemented. This will result in MinIO failing to return object listing after a reboot.
• Target startup time is presently longer than expected - and will be addressed in a future release.

v2.0.0

Gen2 Overview

• DSS can now be deployed with gen2 mode, which utilizes RDD (RDMA Data Direct).
  • This feature enables clients to transfer object data directly from DSS targets without the need to go through the MinIO servers.
  • This allows better performance, as well as improved network and memory resource utilization in the DSS Stack.
  • This feature is integrated with DSS Client APIs and allows for seamless integration with applications using the thin DSS client library.
• To deploy DSS with gen2 mode enabled, it is required that both front-end (in tcp_ip_list) and back-end (in rocev2_ip_list) IP addresses be from RDMA-enabled network interfaces. See dss-ansible README for details.
• dss-ansible will deploy DSS in "gen2" mode simply by setting gen2=true in your Ansible inventory file. The default value is false, which will deploy DSS in gen1 mode (not using the RDD feature, does not require RDMA front-end network).
