File-backed in-memory structured storage for service synchronization

A computing system comprising:

• at least one processor;
• and
• memory having stored computer-executable instructions which, when executed by the at least one processor, implement a method of providing synchronization, the method comprising:
• downloading a batch of changes in a heterogeneous batch, wherein the batch of changes is correlated to an anchor affiliated with a synchronization service, wherein the anchor is a reference point indicating time or relative order;
• serializing the batch of changes and the anchor to a non-volatile storage medium as a heterogeneous set;
• and
• after serializing the batch of changes to a non-volatile storage medium as a heterogeneous set, parsing out entities in the batch of changes into a plurality of different homogeneous collections of entities in in-memory representations, the plurality of different collections each corresponding to a different type of entity.

A computer-implemented method of providing synchronization to a local computing system, the method comprising:

• downloading a batch of changes in a heterogeneous batch, wherein the batch of changes is correlated to an anchor affiliated with a synchronization service, wherein the anchor is a reference point indicating time or relative order;
• serializing the batch of changes and the anchor to a non-volatile storage medium as a heterogeneous set;
• and
• after serializing the batch of changes to a non-volatile storage medium as a heterogeneous set, parsing out entities in the batch of changes into a plurality of different homogeneous collections of entities in in-memory representations, the plurality of different collections each corresponding to a different type of entity.
