  • Hybrid tiered storage for cloud platforms
    Patent number: 12675534
    Abstract: According to examples, a cloud platform implementing a tiered storage that decouples Request Units from storage is disclosed. Data received from partitions that are characterized by corresponding partition keys is stored to the local storage medium of a virtual machine (VM) as hot data. The received data is formatted as immutable segments and stored to a disaggregated storage medium shared by a plurality of VMs. The immutable segments are grouped into sorted runs within the disaggregated storage medium and are further assigned to different levels. The hot data is deleted from a local storage medium when time-to-cold (TTC) criteria are met. The cold data can be accessed for document retrieval via a search key that includes a partition key and a documentID. Additional Request Units can be allocated or de-allocated for a portion of the cold data without moving the cold data.
