SmartData versions 2.6.0 to 2.7.2 introduce major features and performance optimizations, including Tablestore and Raft backend storage for the Namespace service, high availability (HA) for the Namespace service, improved read and write performance, and enhanced block storage and cache modes.
Upgrades to metadata service backend storage
In addition to the original RocksDB solution, these versions introduce Tablestore and Raft as backend storage solutions for cloud-based metadata management.
If you use cache mode and do not require high-performance metadata storage or HA, the default RocksDB solution is simple, practical, and efficient. The Tablestore and Raft solutions provide HA for the metadata service by running multiple Namespace services.
Optimized usage modes
- Block storage mode (Block): For more information, see JindoFS block storage mode usage guide.
- Cache mode (Cache): Supports multiple usage methods, including the same method as block storage mode and the original OSS file system method for different scenarios. For more information, see JindoFS cache mode usage guide.
Permission support
- Unix permissions: Files are assigned 777 permissions.
- Ranger permissions: Supports advanced configurations such as path wildcard characters.
For more information about permissions, see JindoFS permissions.
