COPY-ON-WRITE UPDATE-TRIGGERED CONSISTENCY

摘要

According to an example, copy-on-write (COW) update-triggered consistency may include determining a first shared version related to a shared set of data related to a process involving a first application and a process involving a second application. First and second local versions may be respectively assigned to the shared set of data associated with the first and second applications. Initiation of a commit process by the first or second applications may be determined respectively based on a write to the first or second local versions respectively related to the shared set of data associated with the first or second applications. In response to initiation of the commit process, a second shared version may be generated related to the shared set of data based on the respective processes involving the first and the second applications.

主权项

1. A non-transitory computer readable medium having stored thereon machine readable instructions to provide copy-on-write (COW) update-triggered consistency, the machine readable instructions, when executed, cause at least one processor to:
determine a first shared version related to a shared set of data related to a process involving a first application and a process involving a second application, wherein the shared set of data is resident in a shared central repository of a memory bank; assign first and second local versions respectively to the shared set of data associated with the first and second applications; determine initiation of a commit process by the first or second applications respectively based on a write to the first or second local versions respectively related to the shared set of data associated with the first or second applications; and in response to initiation of the commit process, generate a second shared version related to the shared set of data based on the respective processes involving the first and the second applications.
