Idempotent API in distributed systems. Analysis and suggestions for their development

Elizov A. I.

a comparative analysis of the idempotent API of some distributed systems is given. The problem of possible violation of data consistency when using the GET method in the HTTP protocol when requesting resources with a strict accounting of the number of hits is shown. А proposal was developed to take this feature into account when developing an idempotent API.
