Versioned records management using restart era

A method, implemented at a computing system including one or more processors, for recovering a versioned records management computing system having a restart era that changes when the versioned records management computing system recovers from a crash, the method comprising:

• generating a persistent store that includes a plurality of items that are each marked with a restart era, wherein any item that was created in the current restart era is marked with the current restart era, the persistent store including a first subset of the plurality of items comprising a plurality of records, at least one of the plurality of records including multiple corresponding versions, the persistent store also including a second subset of the plurality of items comprising a collection of objects that conform to an object model such that the object model is used to operate upon the plurality of records via the object collection;
• and
• recovering from a crash, including promoting at least one of the plurality of items in the persistent store to the current restart era in parallel with normal operation of the versioned records management computing system following the crash.

A computer program product comprising one or more computer-readable storage devices having stored thereon computer-executable instructions that are structured such that, when executed by one or more processors of a computing system, cause the computing system to recover versioned records of the computing system in response to a crash, the computer-executable instructions further including instructions to cause the computing system to perform the following:

• generate a persistent store that includes a plurality of items that are each marked with a restart era, wherein any item that was created in the current restart era is marked with the current restart era, the persistent store including a first subset of the plurality of items comprising a plurality of records, at least one of the plurality of records including multiple corresponding versions, the persistent store also including a second subset of the plurality of items comprising a collection of objects that conform to an object model such that the object model is used to operate upon the plurality of records via the object collection;
• and
• recover from a crash, including promoting at least one of the plurality of items in the persistent store to the current restart era in parallel with normal operation of the versioned records management computing system following the crash.
