Embodiment Construction

[0075] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0076] The data upgrade method provided by the embodiment of the present invention provides temporary storage of the data structure and business data during the grayscale period through the data structure change table and the dynamic structure table, and updates the changed data structure and corresponding business data to the source table after the grayscale ends , so as ...

Abstract

The invention discloses a data upgrading and querying method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of receiving a changeregistration request and change detail information corresponding to the change registration request, and generating a data structure change table; receiving a total change request, and executing datastructure change on a source table according to the data structure change table; and according to the data structure change table and the corresponding dynamic structure table, synchronizing the dynamic structure table to the source table after the data structure change is executed. According to the embodiment, the technical problem of data structure conflict caused by parallelism of multiple versions of programs in the gray period can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data upgrading method and device. Background technique [0002] Grayscale release (also known as canary release) refers to a release method that can smoothly transition between black and white. A / B testing can be carried out on it, that is, let some users continue to use product feature A, and some users start to use product feature B. If users have no objection to B, then gradually expand the scope and migrate all users to B Come. Grayscale publishing can ensure the stability of the overall system, and problems can be found and adjusted at the initial grayscale to ensure their impact. [0003] In the grayscale period, there are data structure conflicts in the simultaneous operation of multi-version applications, which are generally handled by data isolation technology. Data isolation creates different data sources for different versions of applications to resolve conflict...
