Optimistic concurrency for collaborative applications

Abstract:

Technologies described herein can be used to support modification to data by a client computing device without a concurrency check. An update to a data document can be received from a client computing device. Contents of the update can be analyzed to determine whether a concurrency check is required before applying the update to the data document. In at least some embodiments, at least part of the contents of the data document can be organized in such a way that multiple, independent modifications can be made to the contents of the data document without concurrency checks. A server computer can be configured to identify updates to these contents of the data document, and to apply the updates to the data document without performing concurrency checks. In at least some embodiments, a list of concurrency-safe data document properties can be accessed when determining whether to omit the concurrency check.
