Latest Patents

One of Zhihao Yao's latest patents is titled "Synchronizing a stale component of a distributed object using a delta component during maintenance." This patent describes a method for enhancing data durability of a base component by utilizing a delta component. The delta component is generated when the base component becomes unavailable, and it includes unwritten storage space that matches the address space of the base component. Write operations intended for the base component are redirected to the delta component, and the affected data blocks are tracked using a bitmap. Once the base component is available again, the data blocks are synchronized from the delta component back to the base component, after which the delta component is removed.

Another notable patent is "Identifying a fault domain for a delta component of a distributed data object." This invention involves placing a delta component of a base component in a target fault domain to enhance data durability. The process includes selecting an appropriate fault domain based on the presence of a witness component or other criteria, ensuring that available fault domains are preserved while enhancing the durability of the distributed data object.
