FINE GRAINED RESOURCE MANAGEMENT FOR ROLLBACK MEMORY OPERATIONS: abstract simplified (17716250)

• This abstract for appeared for patent application number 17716250 Titled 'FINE GRAINED RESOURCE MANAGEMENT FOR ROLLBACK MEMORY OPERATIONS'

Simplified Explanation

The abstract describes a method for managing resources in a system that allows for undo logging sessions. The system maintains a list of available resources for each session and keeps track of the amount of available memory. If a write operation exceeds the available memory for a session, a flag is set and the write is not mirrored. This solves the problem of one session using too much memory and affecting the functioning of other sessions by setting resource limits for each session.

Original Abstract Submitted

Disclosed in some examples are methods, systems, computing devices, and machine-readable mediums in which the system maintains a list of resources available for each rollback session. In some examples, state data is kept that indicates available memory. If a write occurs for a particular session and the amount of available memory for a session has been used, a flag is set in metadata for the memory location and the write is not mirrored. In this manner, the technical problem of one undo logging session using too much memory and preventing other undo logging sessions from properly functioning is solved by the technical solution of setting resource limits for each undo logging session.
